Bacteria and enzymes naturally occur in our bodies. They are a defense against infection and help to stabilize our bodily functions, as well as to break down food sources and keep a healthy balance in our intestines and colon. That is why antibiotics are dangerous if used incorrectly. They do not distinguish between the healthy bacteria and infections. If you destroy the healthy bacteria, you cause an inbalance in the functions of your natural system and that can lead to complications on many levels. Enzymes are cleansing agents that help our body to break down food sources.
The natural food industry has known for years about these healthy bacteria. You find them as cultures in yogurt. Yeast infections are one example. They are caused by an imbalance of bacteria and can be controlled through the use of healthy bacteria, as can thrush. The food industry is guilty of pushing cheap altenatives to what is a simple fix. Buy fresh, keep it simple and enjoy what is available in the season you are living. And belive that sugar is not what we need. Our government has created an imbalance in overprocessed food and has eleminated the oppotunity for farmers to produce the foods we need. Do some research on how sugar is a product that has been injected into our culture. It is cheap and it has provided a huge income to the producers.
What are the importances of bacteria in the field of medicine and the food industry?
Making yogurt taste good.
Reply:If the beneficial bacteria in our gut were wiped out, digestion would become very difficult, as they help break down the different foods.
Bacteria is vital to create cheese, yogert and such things as wine.
Reply:to make hormones,enzymes,interferron .gibric acid, glutamic acid in medicine. in food industry yeast is commonly used. it's used to make beer,wine,vinegar.
in cheese production penicillium is used. Acetobacter and Glucanobacter is used in vinegar produciton.

In which food can Salmonella bacteria be found?
And is Salmonella the full scientifc name that causes enteric stomach problems?
In which food can Salmonella bacteria be found?
Any raw food can give you that bacteria. Runny eggs for example, or even caesar's salad's dressing.
Reply:Chicken,pork any poultry
Reply:any food can pick the germ up off an unclean counter or cutting board, but poultry are one of the main carriers.
Reply:CHICKEN!
Reply:milk
Reply:Salmonella was named after Daniel Elmer Salmon, an American veterinary pathologist who, together with Theobald Smith (better known for his work on anaphylaxis), first discovered the Salmonella bacterium in 1885 from pigs.[2][3] Most cases involve undercooked meat, particularly poultry; other sources have been implicated in Salmonella enterica infections. Blood culture should be undertaken in cases where enteric fever, caused by Salmonella typhi or Salmonella paratyphi is suspected.
Reply:They are called Salmonella typhi and paratyphi (as well as Shigella)
Each different strain is found in specific foods with the proteins and fibers the particualr pathogen requires to breed and live.
Some grown in proteins
some on fibers like vegetables after they break down and begin to rot and some grow in liquids.
Reply:Poultry and eggs or anything that has come in contract with those.

What sizes and shapes do bacteria have?
Bacteria do have fixed size and shape.
Size varies from 0.5 to 50 microns, generally 1 to 5 X 0.5 - 1 Micron. ( 1 micron = a millionth part of a milimeter )
Shape is variation of two basic shapes - spherical i.e. Cocci (singular Coccus ) and cylindrical i.e. rods or Bacillus. All other forms are variations of these two.
Cocci in pairs - Diplococcus
Cocci in cains - Streptococcus
Cocci in clusters - Staphylococcus
Cocci in tetrads - Gaffkia
Cocci in cubes - Sarcina
Rods - Bacillus
Curved rods - comma shaped - Vibrios
Spirals - Spirrilum, Spirochaetes
Filamentous - Actinomycetes
Rods wth tapering ends - Fusobacterium
Rods with bifercated ends - Bifidobaterium
Cells without cell wall do not have fixed shape, these are Mycoplasma.
You will get this information in any basic microbiology book or in wikipedia

they are tiny in size and could be of various shapes like round,cylindrical,snails like,,,,,,,,,,tiny droplets.
Reply:Bacilli (sing. bacillus) are elongated, like a rod (baculus in Latin).
Cocci (sing. coccus) are round, like a coconut.
Spirilla (sing. spirillum) are spiral.
When they come in a conga line, they are prefixed "strepto-" so "streptococci" means several spherical ones lined up.
When they come in clusters like grapes, they are prefixed "staphylo-" so "staphylococci" means a cluster of the round ones.
They go from 0.1 micrometres (that is, 0.1 of a millionth of a metre) to 600 micrometres. Cocci are smaller than bacilli, and these are smaller than or equal to spirilla.

Are there similar water consumption/bacteria concerns in the country of Belize like there are in Mexico.?
I am considering taking a vacation to Belize and want to understand the risks of consuming the food/water. We all know about the restrictions in Mexico but you dont hear much about central and south america. I get very sick everytime I go to Mexico regardless of how carefull I am and dont want to have to experience that if I dont have to.
Are there similar water consumption/bacteria concerns in the country of Belize like there are in Mexico.?
In Belize you have to worry about the water but not the food. My wife and I moved down here with two kids (8 and 4) about 18 months ago from the States. We have travel across Belize and eaten in many different places and many types of food with no problems - none. Some of the primary places we have eaten are San Ignacio, Belmopan, Belize City, Dangriga, P.G., and a couple of Cayes - these are just the primary places we have eaten food in several other parts of Belize as well and no issues.
In the area of water we follow the saying "When in Roman do as the Romans do." Here in Belize locals drink bottled water and, in general, so do we. There are a few times we have drank straight from the tap but I would not make it a practice - the water systems here are just not good enough.
In short - come to Belize, have a great time, eat food as you like, but be careful about drinking the water - you probably would not get sick by drinking it but why take the chance.
Reply:Yes, water and food are pretty similar than in Mexico, take precautions.
Reply:The concerns in belize are probably worse than in Mexico, curently. The country is a lot poorer than Mexico on average, and much of the infrastructure is substandard.
On the other hand in some of the nicer resorts that are isolated from any local towns they probably have relatively clean water.
If you travel around Latin America enough you eventually will get sick from the local bacteria. After you get over it a few times you will be relatively immune like the locals. One should be prudent, but if one eats the local food eventually you will get sick. Drinking bottled water helps, but all of the food and dishes etc will be washed in the local water so if it is there, you will get exposed eventually.

If armpits smell because of bacteria in them, not from sweat, why doesn't anyone make antibacterial deodorant?
I'm not sure that armpits do smell because of bacteria....if they were to blame, using rubbing alcohol would be enough to kill them. Sweat is not only trying to keep you cool, it's also getting rid of toxins in your body. Anything that you eat that's bad for you or that your body doesn't want is going to come out some way or other, and sweat is one way to get rid of those chemicals that might hurt your body. The best way to get rid of smells is to make an adjustment in your diet.

How would a culture of bacteria being heated alter the fatty acid composition of the lipid bilayer?
The lipids would move and rotate faster and more often...the bilayer would become more fluid. The bacteria would eventually adapt to the heat and the bilayer would become composed of more long chain satuated fatty acids to decrease the fluidity.
Does freezing yogurt kill the bacteria (the good type)?
Does freezing yogurt destroy or alter the effectiveness of the live cultures?
You can freeze yogurt. Yogurt that has been frozen and thawed will have a different look and texture than fresh yogurt. The cultures become dormant when frozen, but once thawed either in the refrigerator or by your body heat when ingested; they will become live and active once again. There will be a few cultures that do die, but there are so many billions in our products, that it is truly insignificant.
Does freezing yogurt kill the bacteria (the good type)?
No. Freezing won't kill bacteria (good or bad) it just temporarily stops growth. Cooking, on the other hand will.
Reply:It just becomes dormant. When the yoghurt returns to its normal temperature, the bacteria wake up again and can also multiply depending on the temperature. I don't know how the yoghurt tastes after being thawed out though.

How can we culture anaerobes(bacteria) without using CO2 incubator?
not necessaily strict
How can we culture anaerobes(bacteria) without using CO2 incubator?
If you have a container with a tight sealing lid, you can put a lit candle in with your plates, and that will burn up most of the available oxygen in the container.
It's not a complete anaerobic chamber, for that you would need commercially prepared packets. CO2 incubator are not anaerobic, they are usually just ran at a 5-10% concentration of the gas, as this aids in growth of some bacteria.

How does Binary Fission by bacteria differ from mitosis?
There are no spindle fibres formed, absence of centrioles, chromosomes are not pulled to the opposite poles of the cell, thus no stages such as prophase, metaphase, anaphase or telophase occurs.
However, both undergoes cytokinesis.
How does Binary Fission by bacteria differ from mitosis?
The bacteria has no spindle fibers.
Reply:the Bacteria has no sindle !! just lended it
Reply:Binary fission makes exact copies of the parent cell (as well, only one bacteria cell is needed, as opposed to mitosis which needs two), where as mitosis produces cells that are not genetically identical to either parent. Thus, mitosis allows for more genetic variability than binary fission does.

Oiy... its been a few years since microbiology class. I'm not sure if these are the specific ones that your homework question is asking for, but are the most common topics in molecular work in molecular botanical sciences
uptake of plasmid DNA either through conjugation (as in the case of e-coli)
horizontal transfer (external DNA uptaken through the environment which is the concern with using GMO or through close proximatey of its host such as with agrobacterium)
transformation of chemically or electrically competant cells (as in the case of cloning reactions using bactia)
bacteriophages

How do Protists interact with Bacteria?
Like, do they compete for living space and food? Do they harm each other? Do they benefit each other?
I can't seem to find info on it.
How do Protists interact with Bacteria?
What difference is there between bacteria and protists? This distinction is founded on the complexity of a cell's organization. The cellular organization of bacteria is particularly simple -they do not have membranes binding their nuclear material- and for this reason they are also named prokaryotes ("before-nucleus"). The cellular organization of protists is more complex -they have a membrane-bound nucleus (and other organelles distinct from the cytoplasm)- and they are therefore called eukaryotes ("true-nucleus"). Animals, plants and fungi, being derived from protists, are also eukaryotes.
Protists are microscopical, unicellular eukaryotes. They generally live in water.
Not all microorganisms are protists. Another "kingdom" contains unicellular microorganisms, the Monera. Bacteria belong to this kingdom.
Reply:They eat them.
Reply:Lichens are symbiotic associations of a fungus (the mycobiont) with a photosynthetic partner (the photobiont also known as the phycobiont) that can produce food for the lichen from sunlight. The photobiont is usually either green algae or cyanobacteria. A few lichens are known to contain yellow-green algae or, in one case, a brown alga. Some lichens contain both green algae and cyanobacteria as photobionts; in these cases, the cyanobacteria symbiont component may specialize in fixing atmospheric nitrogen for metabolic use. The word is pronounced lie-k'n (IPA: [laɪkən]).[1]
The body (thallus) of most lichens is quite different from that of either the fungus or alga growing separately, and may strikingly resemble simple plants in form and growth (Sanders 2001). The fungus surrounds the algal cells, often enclosing them within complex fungal tissues unique to lichen associations; however, the algal cells are never enclosed inside the fungal cells themselves. The fungus may or may not penetrate into the algal cells with fine hyphal protrusions.
In general, the symbiosis is considered obligatory for successful growth and reproduction of the fungus; however, the significance for the algal symbiont is less clear. For some algae, the symbiosis may be obligatory for survival in a particular habitat; in other cases, the symbiosis might not be advantageous for the alga. Thus, there is some controversy as to whether the lichen symbiosis should be considered an example of mutualism or parasitism or commensalism. Nonetheless, the lichen is typically a highly stable association which probably extends the ecological range of both partners

Does whistling spread germs and bacteria?
Under normal conditions it doesn't. What can happen is tiny droplets of saliva might be ejected. If you are sick with specific kind of bacterialor viral infection then that saliva might infect someone else. But if you are a healthy person it shouldn't be a problem.

How does nuclear radiation kill bacteria?
I know that UV rays are good at killing bacteria. It disrupts the DNA in the bacterium so that it can't replicate properly.
How does nuclear radiation kill bacteria?
Radiation kills all living beings by disrupting their DNA at low ranges, and by disrupting their molecules at high doses. It will kill all biological matter, bacterial and otherwise.
Reply:dna denatures from the heat
Reply:Simply put, it fries the bacteria cellular structure, the same way as it kills cancer cells.

Why does asexual reproduction in bacteria make it hard to define their species?
The previous answer has some significant errors. Asexual reproduction is not mitosis. Mitosis only occurs in eukaryotes. Bacteria asexually reproduce by binary fission or budding. Also, while bacteria don't reproduce sexually by definition, they do regularly exchange genetic material.
Anyway, to answer your question, the difficulty with bacteria is that it makes it difficult to use the old species concept of: "Two organisms that are able to reproduce naturally to produce fertile offspring," (taken from wikipedia) since that definition requires sexual reproduction. Note there's also some other reasons why it's hard to define a bacterial species.
Why does asexual reproduction in bacteria make it hard to define their species?
Asexual reproduction, also known as mitosis, always makes identical copies of the same cell, in this case, bacteria. Every detail is the same in these bacteria, so nothing changes and this process goes on and on and on. Sexual reproduction (meiosis) involves the crossing over of alleles in homologous chromosomes (chromosomes for the same trait), creating genetic variation. Genetic variation is a random process that makes it impossible for organisms who reproduce sexually to be exactly the same. But most bacteria can't reproduce sexually, so their copies will always be the same as the one before. This makes less distinction between different kinds of bacteria. The changes between them occurred so slowly.

What are the sympathys for bacteria eating the line of your stomach?
I'm assuming you meant symptoms and the bacteria you might be referring to is H. Pylori. These are the symptoms of an ulcer:
Abdominal discomfort is the most common symptom. This discomfort usually
is a dull, gnawing ache
comes and goes for several days or weeks
occurs 2 to 3 hours after a meal
occurs in the middle of the night—when the stomach is empty
is relieved by eating
is relieved by antacid medications
Other symptoms include
weight loss
poor appetite
bloating
burping
nausea
vomiting
Some people experience only very mild symptoms, or none at all.
Reply:"Get well soon, stomach line."

How is it possible that bacteria enters the vagina during intercourse if the woman is clean?

How is it possible that bacteria enters the vagina during intercourse if the woman is clean?
Women should go pee before sex to avoid a UTI. But anyhow, I would imagine germs and bacteria get pushed in there during sex.
Reply:often due to enviromental factors and quite often, the penis
Reply:The urethra is not the same hole as the vagina, so bacteria in the vagina has nothing to do with getting a UTI.
There is also some bacteria normally living in the entrance of the urethra anyway. Usually they don't get up into the bladder to make a UTI, but in my experience sex in certain positions pushes them up in there and I get a UTI. There really isn't any way to remove all the bacteria from your skin or genital area, so cleaning yourself may be helpful but will not 100% prevent UTIs. Peeing before and after sex may help, and/or drinking a lot of water to help you pee more, to flush any extra bacteria out. Please do some more research on it as I don't think you understand what is going on in the first place.
No matter how clean you try to get your skin, some bacteria will still remain on it, but many kinds are normal, and by being there they compete with any bad bacteria or yeast that you may come in contact with, thereby helping keep you healthy.
A healthy vagina has A LOT of bacteria in it already, mostly Lactobacillus acidophilus (the same stuff in supplements that helps digest milk). Acidophilus means acid-lover, this bacteria makes the vagina normally very acidic (and why most douches use vinegar, but douches reduce the number of lactobacillus, which is unhealthy). The acidity of the vagina is important because it helps kill any other potentially harmful bacteria or yeast that may get in there, from the skin or objects, especially fecal bacteria which can cause a nasty infection. Minor vaginal infections can be cured by inserting Acidophilus supplements into the vagina, however, and it's a lot cheaper and much healthier than going to the doctor and taking antibiotics. Just make sure Lactobacillus acidophilus is the only bacteria in the supplement.

What the difference between a bacteria and a virus?
Virus contains a nucleic acid core wrapped in a protein coat. This coat is called a capsid. Some viruses contain an envelope, constructed from the host cell membrane. The nucleic acid core may be DNA ( double strand, single strand), or RNA ( single strand, double strand), but never both. The shape of these viruses vary from spherical, cylindrical, bullet-shaped , to amorphous shaped particles. They vary in diameter from 18 to 300 nm. Viruses must infect a living cell. Viruses are obligate intracellular parasites. Some viruses are hardier than others ( hepatitis virus can withstand short periods of boiling; most viruses are destroyed by this).
Bacteria are true cells. Their DNA is singular and circular and found in the nucleoid region of the bacterial cell. They also contain small double strand ring of DNA called PLASMIDS.
Most bacteria reproduce by binary fission. There is only one origin of replication. 2 replication forks move in opposite directions. Bacteria can completely divide in 20 minutes under optimal conditions. They are either free-living or parasitic like the virus. Most bacteria are helpful though some cause some serious diseases. They mainly help us with decomposition of dead material.

Reply:Bacteria (singular: bacterium) are a major group of living organisms. The term "bacteria" has variously applied to all prokaryotes or to a major group of them, otherwise called the eubacteria, depending on ideas about their relationships. Here, bacteria is used specifically to refer to the eubacteria. Another major group of bacteria (used in the broadest, non-taxonomic sense) are the Archaea. The study of bacteria is known as bacteriology, a subfield of microbiology.
A virus (Latin, poison) is a submicroscopic particle that can infect the cells of a biological organism. At the most basic level viruses consist of genetic material contained within a protective protein shell called a capsid, which distinguishes them from other virus-like particles such as prions and viroids. The study of viruses is known as virology, and those who study viruses are called virologists.

Bacteria are living things
Viruses are nonliving and inert outside of a living cell.
Bacteria reproduce themselves, by division or rarely by partially fusing with another bacteria (of the same kind) to swap genes, then breaking away and dividing (the origin of sex).
Viruses can't reproduce, their protein capsules have what are like docking clamps that trick a living cell into giving them access to it's insides. The genetic instructions of the virus then hijack the cells own inner workings to produce multiple copies of itself. The cell fills with the viral progeny, then dies and pops, releasing the horde of viruses to begin the process anew.

Reply:A bacterium is a single-celled organism with the ability to grow and replicate independently in an environment that meets its needs (temperature, moisture, nutrients, gases). Bacteria can grow exponentially, so long as there are no limiting resources.
A virus cannot grow and replicate independently. It is designed to deliver its nuclear material (RNA or DNA) into a host cell (animal, plant or protist) and take over the host's cellular machinery, causing it to produce many copies of the virus. These are principally nuclear material and coat proteins, which have the ability to self-assemble within the host cell. When the host cell's ability to synthesise viral materials is depleted, it dies and releases the new viruses into the environment or into the surrounding tissues. The released viruses must reach a new host cell in order to replicate themselves.
Outside the host cells, viruses are passive objects without the vital signs common to all other living things, such as respiration or energy metabolism.
Reply:Bacteria contain the genetic blueprint (DNA) and all the tools (ribosomes, proteins, etc.) they need to reproduce themselves.
Viruses are moochers. They contain only a limited genetic blueprint and they don't have the necessary building tools. They have to invade other cells and hijack their cellular machinery to reproduce. Viruses invade by attaching to a cell and injecting their genes or by being swallowed up by the cell.

Reply:Bacteria and viruses are both small microscopic organisms that cannot be seen by a naked eye. Overall viruses are much much smaller than bacteria although there are some few viruses that are bigger than the smallest bacteria.
Bacteria are regarded as living things whereas it is still unclear to scientists whether to call viruses living organism as they do not fulfil some of the requirements of living things. Viruses need other living organism to reproduce themselves a process called viral-replication.
Both bacteria and viruses can infect other living things such as plants, animals and humans. However, bacteria can also be infected by viruses.
Both bacteria and viruses are well known for infecting other living things causing disease to humans (also plants and animals). Bacteria causes diseases like tuberculosis. Viruses causes infections like HIV/AIDS, Measles, Chicken Pox and lots of other infections.
Diseases caused by bacteria are treated with drugs called by anti-biotics. It is very difficult to find drugs that can treat or cure viruses the best way is to prevent their infections by vaccinations. There are however a few drugs that have some effects on viruses called the anti-viral drugs such as the now common anti-HIV drugs( these have some effects on HIV but do not cure it).
Although bacteria and viruses are both often associated with diseases they have useful causes too.
For example there are nitrogen fixing bacteria that fixes nitrogen which non-nitrogen fixing plants can use. Other bacteria live in the intestines of humans and animals and helps to stop the growth of other harmful bacteria.
Other bacteria help to decompose biological wastes. Indeed many bacteria are used to ferment foods like the yougart and cheeses. Others are used to produce drugs like the penicillins and insulin (used for treatment of Diabetes.)
Many scientists are beggining to find uses of viruses too. Viruses can potentially be a source of energy when introduced in energy producing cells. Some viruses have been used to aid in the study of what goes on in small cells becuase there presence in the cells increases the activities in dividing cells.
Reply:For a start,size.Bacteria,although small are in the order of ten to a hundred times larger than most viruses. A bacterium is a complex grouping of organelles,functions and structures whereas a virus is essentially just a bag of biological dirty tricks and subterfuges with a neat line in blocking the receptor sites of its host and the ability to "shape shift",ie mutate one step faster than the hosts defenses..This is it's main means of attack.A bacterium on the other hand relies on sheer force of numbers to win.That and the fact that,as with all living things,they excrete and those excretions are what poison the victim,making them feel ill.
There is more,but thats all I have time for just now,hope its been some use to you.

Reply:Bacteria are mainly defeated by the one of the bodies main defenses (white cells) the particular type is Phagocytes these consume the bacteria and literally digest them. Viruses are deactivated by lymphocytes (another white cell). Also viruses reproduce by injecting RNA (ribonucleic acid) and this joins up with the RNA in the cell its injected by pairing the base cells guanine to cytosene and adamine to thyamine where other nasties will burst out. Bacteria reproduce differently by splitting into two as all the DNA is contained within the bacteria already

Diseases caused by bacteria are treated with drugs called by anti-biotics. It is very difficult to find drugs that can treat or cure viruses the best way is to prevent their infections by vaccinations. There are however a few drugs that have some effects on viruses called the anti-viral drugs such as the now common anti-HIV drugs( these have some effects on HIV but do not cure it).
Although bacteria and viruses are both often associated with diseases they have useful causes too.
For example there are nitrogen fixing bacteria that fixes nitrogen which non-nitrogen fixing plants can use. Other bacteria live in the intestines of humans and animals and helps to stop the growth of other harmful bacteria.
Other bacteria help to decompose biological wastes. Indeed many bacteria are used to ferment foods like the yougart and cheeses. Others are used to produce drugs like the penicillins and insulin (used for treatment of Diabetes.)
Many scientists are beggining to find uses of viruses too. Viruses can potentially be a source of energy when introduced in energy producing cells. Some viruses have been used to aid in the study of what goes on in small cells becuase there presence in the cells increases the activities in dividing cells.
Reply:For a start,size.Bacteria,although small are in the order of ten to a hundred times larger than most viruses. A bacterium is a complex grouping of organelles,functions and structures whereas a virus is essentially just a bag of biological dirty tricks and subterfuges with a neat line in blocking the receptor sites of its host and the ability to "shape shift",ie mutate one step faster than the hosts defenses..This is it's main means of attack.A bacterium on the other hand relies on sheer force of numbers to win.That and the fact that,as with all living things,they excrete and those excretions are what poison the victim,making them feel ill.
There is more,but thats all I have time for just now,hope its been some use to you.
Reply:Bacteria is like a nice dog that can doo good things and bad things. A virus is like a cat that is only pure evil!!!
Reply:Bacteria are mainly defeated by the one of the bodies main defenses (white cells) the particular type is Phagocytes these consume the bacteria and literally digest them. Viruses are deactivated by lymphocytes (another white cell). Also viruses reproduce by injecting RNA (ribonucleic acid) and this joins up with the RNA in the cell its injected by pairing the base cells guanine to cytosene and adamine to thyamine where other nasties will burst out. Bacteria reproduce differently by splitting into two as all the DNA is contained within the bacteria already

Biology Homework Question
What's the difference between Bacteria and a Virus?
Bacteria = unicellular organism
Viruses = smallest microorganism
Bacteria is either good or bad to us. (We had bacteria in our body that helps cellular works)
Viruses meanwhile, utilises the cellular components of host cell to replicate many copies of itself. Viruses that infect bacteria are called 'bacteriophages'.
Reply:Bacteria multiplies itself to survive and spread, it is also able to be cured by anti-biotics.
Virus' infect other cells to survive and spread, but it's not able to be cured by anti-biotics.
Reply:A virus is only composed of Genetic material (DNA) and a protein cote and it cant multiply by its self it first needs to invade a bacteria...

Where online can I buy bacteria such as E.Coli and Staphylococci?
I need samples for my science fair project, but where on earth do you buy these?
Where online can I buy bacteria such as E.Coli and Staphylococci?
Wow, you folks all need to calm down. E. coli and Staph are not serious bioterror risks.
Only one form of E.coli is pathogenic, and their are also several strains of staph that don't cause any disease.
However, it really does depend on what your project is all about. In order to properly manipulate bacteria, you need aspetic techiques and the right tools. It also requires the proper media to grow, and incubaters at 37 degrees. They're not things you can just play with at home.
Depending on your project, you might be able to get a lab to help you. Local community colleges, public health labs, or even some high school bio labs might be able to help with what you need.

Reply:Actually, the nitrogen-fixing bacteria on the roots of legumes help replenish the nitrogen in the soil.
Reply:When a field has been heavily used (ie by growing corn or some other nitrogen-stripping crop) for several years, the traditional next step is to let it "lie fallow" for a year or so - which may entail planting it in beans or alfalfa or some other crop which replenishes the soil nitrogen levels. These plants have nodules in the roots which serve as living quarters for very interesting bacteria known as 'nitrogen-fixing' bacteria because they can take elemental nitrogen (N2) and rebuild it into nitrogen compounds that plants can pick up and use to build seeds with.

My cat diagnosed with anaerobic bacteria in her leg, now her face and limbs are swollen. Not in pain anymore.?
She's on 2 medications but she's not eating, only drinking (excessively). What to do??
My cat diagnosed with anaerobic bacteria in her leg, now her face and limbs are swollen. Not in pain anymore.?
She needs to be taken back to the Vet ASAP.
Not eating is worrisome enough, but the drinking excessively is NEVER a good sign.
The medication maybe effecting her kidneys or liver and the fact that she's swollen is also not a good sign.
Please, take her to the Vet NOW!
Good luck, I hope kitty makes a full recovery.
Reply:If she is drinking excessively and not eating it could mean that the antibiotics are damaging her kidneys. Take her to the vet immediately to do a blood test and check her urea and creatinine levels. You can save her if you do that quickly.
Reply:If she's not eating and swollen, she needs to go back to the vet ASAP. I'm sure she is still painful and may be too sick to show the normal signs of pain. Cats can get very ill form not eating, and the swelling may indicate that the infection is spreading. It sounds like she may need IV antibiotics and a blood panel run to check her kidney/liver function as well as her white blood call count.

Anthrax is real and found in nature. That X is just used as a way to make a point. Anthrax has been made into a weapon by many governments.
Reply:Unfortunately, Anthrax is all too real. They had it back in the early 1800's when this country was still being settled. There were many farmers and ranchers who would lose their cattle and horses along with other stock animals to anthrax.

Does contact solution kill the bacteria and/or viruses that cause conjunctivitis (pink eye)?
So it would thus clean all of the offending microbes from your contacts, if you wore a pair you tried on when you had pink eye?
Does contact solution kill the bacteria and/or viruses that cause conjunctivitis (pink eye)?
Really, just toss your contact lenses. I almost went blind in one eye from contact lenses which I wore while I had gotten pink eye. It quickly turned pink eye into a corneal ulcer. So no, solution doesn't kill pinkeye. Throw out your old contact lenses now.
edit: contact lens solution is not a cure-all that gets rid of every microbe in existence. Certain Amoebas, fungi and certainly viruses can easily exist on a contact lens even after being cleaned in solution. Since pink-eye has numerous causes, from allergies to viruses to bacteria, there is no way to know if contact lens solution will necessarily kill the offending microbe. Since the worst case scenerio is going blind as mentioned above, why would you take such a risk?
Reply:No it doesn't. Throw out the lenses and clear up the pink eye before you start a new pair. Otherwise you'll contaminate that one too.
Reply:Throw them out and wear glasses until it's definitely better.
Reply:Unfortunately not. The contacts you put on when you have pink eye (conjuctivitis) have to be thrown away- and if not- you WILL continue to re-infect yourself

What is the size ratio between a viruse and a bacteria? and a bacteria versus an eukaryotic cell?
explanation please...
thanx
What is the size ratio between a viruse and a bacteria? and a bacteria versus an eukaryotic cell?
Viruses are 15 to 150 nM with many in the range of 20 to 40 nM. Bacteria are from 350 to 1000 nM.
Eukaryotic cells range in size between 2 and 100 micrometers
1 nanometer (nM) is 10^-9M
1 micrometer (muM) is 10^-6M

What is the difference of bacteria from all other living organism?
the biggest difference is that bacteria lack a nucleus and other membrane bound organelles!!! they are the only kingdom(s) which have this property. All other living organisms are eukaryotic or have a nucleus and other membrane bound organelles e.g. motochondria, endoplasmic reticulum, lysosomes, etc Bacteria can then be divided into Archaea and Eubacteria based upon the development of their cell walls as well as the way in which protein are made (differ in rRNA and transcriptive process)
What is the difference of bacteria from all other living organism?
they are in a different kingdom (ex: Animalia, Plantae...)
Reply:The main difference is the way they make their cell walls. They use peptidoglycan, while Archaeans don't. Plants use cellulose and Fungi use chitin.

What is a colony of bacteria?
A colony of bacteria, sometimes referred to as a culture, is simply, a single type of bacteria that replicates itself many many times and forms a small mass. In order to see a colony of bacteria, typically a species will be placed on a nutrient rich media, like agar for instance in a petri dish. This newly innoculated agar will be placed in an incubator at the optimal temperature for that given species of bacteria. After 24 hours, a once spotless agar plate will be covered in tiny dots, these are the colonies beginning to grow. Millions of bacterial cells can be procuced from one single original cell, which multiplies exponentially. 1 becomes 2,4,8,16,32 etc.....................until you have millions. I hope that answers your question!

Is a simple cell a bacteria or a virus?
Thanks for answering! ♥
Is a simple cell a bacteria or a virus?
It depends on what you mean by a "simple cell". Most bacteria are cells or chains or colonies of cells but not all cells are bacteria. E.G. skin cells, muscle cells (not simple), brain cells. A virus is not considered a cell. It lacks the complicated machinery of a living cell that allows it to multiply (among other things). That's why a virus needs to get into a living cell to use the cell's machinery to make copies of itself. Different kinds of viruses do this differently but the idea is basically the same. Invade a cell, take over it's production tools, and make copies of itself. Libby T.
Reply:Bacteria. Viruses aren't really cells at all.
Reply:bacteria
Reply:Viruses are not cellular in nature. They are composed of organic material, but they fall short of designation as cellular as they have the inability to duplicate their genetic material and require a host cell to do so.
Reply:A simple cell is just that - a cell.
This excludes viruses, since viruses are just genetic material (DNA, RNA or both) coated with protein.
Other than that, a simple cell can be any living thing you can name - human cells, plant cells, animal cells, bacteria cells etc.

Freezing food will kill all bacteria? True or False?
i think it is false but my brother disagrees
Freezing food will kill all bacteria? True or False?
False (you're right)
Freezing to 0 °F inactivates any microbes -- bacteria, yeasts and molds - - present in food. Once thawed, however, these microbes can again become active, multiplying under the right conditions to levels that can lead to foodborne illness. Since they will then grow at about the same rate as microorganisms on fresh food, you must handle thawed items as you would any perishable food.
Trichina and other parasites can be destroyed by sub-zero freezing temperatures. It is not recommended to rely on home freezing to destroy trichina. Thorough cooking will destroy all parasites.

Reply:Definitely false. Cold temperatures will cause the bacteria to produce spores which are a resistant and metabolically inactive form. In proper conditions like thawing the frozen food, the spore will morph into the bacteria that produced it and reinfect the food.

Reply:Will freezing food kill the bacteria that is in that food?
They say that you should not refreeze food that you have already thawed out. Why not? maybe because freezing will not kill the bacteria that has grown while it was out?
My doctor just gave me some medicine to take. It is Lactobacillus tablets. These contain bacteria. At the pharmacy they where kept refrigirated. On the label it says to keep refrigerated.
Reply:true
Reply:its false..there are some bacteria which survive at extreme conditions.. so freezing wont kill them!
Reply:False. It will immobilise the bacteria, but once the temperature gets higher they will be mobile again.
To kill bacteria you need to heat it up. This denatures the bacteria enzymes and even if the temperature drops again the bacteria wont 'work'.
Reply:true.
freezing is another term for crystalizing.
no living thing or organism can survive being crystalized except viruses.
yes. all bacteria will die.

A dentist once told me that Dr Pepper contains the bacteria, lactobacilli, that also causes cavities. does it?
I am unable to find this any where online or on any labels of Dr Pepper and we all know that not every ingredient is listed on the nutrition labels. So i am looking to see if this is true and where i can find this information. It is for my fifth grade daughters social studies project.

Lactobacilii are the bacteria found in yogurt, not soda. They are what make the milk thicken and sour into yogurt, and are also found in your digestive tract. If your dentist told you that he was either pulling your leg or mistaken. Sodas do, however, contain acids that are damaging to tooth enamel, as well as that they are a strong sugar solution that hurts enamel because you practically bathe your teeth in it when you drink a soda. Diet sodas, however, do not damage your teeth as much because they don't contain sugar.
Reply:1st answer = reliable but you can still drink soda without ruining your teeth...just use a straw.
Reply:I dont think its true. Dr. Peper is too acidic for any life form to survive in it, there is no oxygen in the bottle or can, only carbon dioxide, so i dont think its true.

What is the function of bacteria that live in the digestive tracts of ruminants such as cows?
they break down cellulose to provide energy to the ruminant. Most of the ruminants energy comes from volitile fatty acids.
these bacteria are also a source of protein once they pass further down the GI tract. They make vitamins as well. Ruminants are wonderful.

Can photon.lites kill any bacteria and viruses if yes maybe it canbe the cure for HIV???
There is what is known as the germicidal line at 254 nm (this is in the UV) This disrupts the DNA of most living organisms.
But as other posters mentioned, it would affect a human host's cells as well.
Still, I've had similar ideas, and I think there may be ways to approach this.
Can photon.lites kill any bacteria and viruses if yes maybe it canbe the cure for HIV???
Photons have to be of a specific energy ( wavelength) to kill bacteria typically in the UV range, think of it as giving bacteria a serious sunburn.
But the aids virus lives in the human body, this much energy will more likely kill the person before it kills all the HIV virus.
Good thinking though
Reply:the electromagnetic energy would indeed kill bacteria and viruses, but it would also kill the tissue on the person you are trying to cure. so, in order to irradicate the disease, you would have to burn the person alive.
Reply:bacteria and virus are 2 different things. you have to tune the light to get it to work as you said, and that's complicated.

100,000,000:50
10,000,000:5
2,000,000:1 is your dilution factor.
I assume you would want to keep these sterile? So use falcon tubes with 9 mls of Lb in each to do the dilutions:
the more dilutions you do, the more accurate it is..
1 ml into 9 mls - do this 6 times, but in the last dilution transfer 2 mls into 8 mls..
if you feel lazy, you can decrease the numer of dilutions by transfering 100 ul into 10 mls, and doing it only 3 times..

How is it that some bacteria live in the hot springs of Yellowstone Park at temperature up as high as 73 C?
another biology Question
How is it that some bacteria live in the hot springs of Yellowstone Park at temperature up as high as 73 C?
Extreme thermophiles have adapted unique ways to surviving harsh conditions. They're enzymes are specially designed to resist denaturing at high temperatures. What's really amazing is their DNA. Extremophile DNA is positively supercoiled (this describes the way it is twisted around itself) which makes it harder to separate the strands. DNA in most other species is negatively supercoiled (meaning it's wound up on itself in the opposite direction as positively supercoiled DNA). Since DNA is the building block of life, it makes sense that you need to be able to protect it from the environment. Extremophiles do just that by positively supercoiling it. It is much more resistant to heat denaturing than other DNA would be, which helps the bacteria to survive.
Reply:http://www.biologynews.net/archives/2006...
Good question.
Reply:Because they are xenophiles
Reply:Hold on to your hats people. Highest temperature where bacteria have been isolated from is 121 degrees C. It is theorised that we may find them up to 140degrees C.
This is possible because they have adapted their enzymes to work at high temperatures. Also the DNA has special chaperone proteins that prevent the DNA from dissociating from the heat. They are truely remarkable organisms. The limit we think will be the temperature at which ATP breaks down on its own accord, and as the primary energy source for all living organsims, that we be catastrophic for them.
Reply:Organisms which live in such high temperatures are known as thermophiles. They can live in such conditions because of their structure. They have special, strong cell walls which can withstand the heat for example. Their enzymes work optimally at those temperatures. Essentially it because of how they have evolved, or more acurately, not.
When Life first appeared on Earth, it was a much hotter place than it is now! As such, originally, all forms of life could live under such conditions, in fact in most cases even hotter. gradually the Earth began to cool, and new life forms appeared which could exist in these new conditions.
Thermophilic bacteria such as those that are found in hot springs are, in evolutionary terms, very very old. Thay haven't really evolved/adapted to live in hot environments as such, they've just stayed the way they were to start with! However, because their structure is specialised to survive hot conditions, if you were to move them, and put them somewhere more 'normal', they would not survive. This is mainly because their enzymes (vital for energy production, replication etc) are designed to work at high temperatures, and will not work at low ones. All bacteria have a certain range of conditions in which they can live. If you take that away from them, they die.

Applications of iron and sulpher bacteria?
now a days how it used in environment?
Applications of iron and sulpher bacteria?
In the environment, sulphate-reducing bacteria reduce sulphate (SO4 2+) to sulphide (S 2-), using that as an oxidising process to provide energy. Typically, hydrogen sulphide (H2S) is released
Sulphur is not converted into any organic compounds in the bacteria, and they normally exist in low-oxygen envirnments (like swamps and intestines), where they break down cellulose-rich compounds.
Reply:I'm not really sure...
But some iron or sulphur bacteria are used to degrade some chemical waste that contain high Fe or S. Their ability to use Fe or S as the source of energy is the main feature that used in some bioremediation.

Reply:Most bacterias are killed in boiling water. However, some bacteria survive on higher temperature.
Reply:bacteria have an ability to form a hard casement in adverse conditions, so it depends on the amount of heat,
Reply:A simple answer to your question is no. In terms of temperature, bacteria can be devided into four classes: The pyscrophiles, mesophiles, thermaphiles and hyperthermaphiles. The Pyscrophiles live below 0 dgrees C, mesophiles between about 10 and 40 degrees C.
Thermaphiles live up to around 80 degrees C, and if you put these into an autoclave, and syubject them to high temperature eg 100, then they will be killed.
The highest temperature that a bacterium has been isolated from is a whooping 121 degrees C. The name of the organism has escaped me, but i'll go look for it again. It was isolated from a volcanic vent i believe. Various experts have estimated the highest temperature bacteria can live at at being around 140 degrees, since above this temperature organic compounds such as ATP will no longer be stable enough, and so life as we know it could not exist.

Can you treat mold or bacteria in a matress from a spill?
You can use sprays like Lysol. It depends on how deep it goes of course. You can shampoo a mattress just like you would a rug. When you bring in the rug doctor use it first to do the mattress! Then set up a fan to help it dry quickly. It is really a good idea to clean your mattress this way as it pulls the dead skin away from it and if you have someone with allergies,you probably have learned this trick already.

The importance of identifying unknown bacteria?
Knowing how a bacteria works and how it is structured means knowing how it can affect humans. For example, if a bacteria can make a person ill, but it has something called a beta-lactam ring in its cell wall, that is good to know because a drug that works on the beta-lactam ring is able to kill the bacteria.
Unknown bacteria may also have clinical uses. Many pharmaceutical drugs are based on products made by organisms. Penicillins (which may work in the above-described scenario) is actually isolated from a fungus. Digitalis and digoxin, cardiac drugs, come from the foxglove plant. It is very possible that this unidentified bacteria may have something it produces that would lead to a medical breakthrough.

What is the healthiest yogurt bacteria culture? Is it the one that reduces cholesterol? What's its name?
all the probiotics are good no matter their culture because they all work the same. all of them help to lower the cholesterol when combined with a varied diet and they have other benefits as well (lower the incidence of colon cancer, better function of the gut). i would recommend you to take a supplement with just probiotic bacteria (2 billion bacteria per gram) in it because yogurts that claim to have probiotics in them have very low concentrations so they don't really work. one of the most well known is the Lactobacillus acidophilus. another thing that i would strongly recommend is that you don't take any of the small bottle drinks claiming to have live culture in them because they contain sugar and sugar kills bacteria, and lastly they also contain MODIFIED starch; all of them.

What is the healthiest yogurt bacteria culture? Is it the one that reduces cholesterol? What's its name?
all the probiotics are good no matter their culture because they all work the same. all of them help to lower the cholesterol when combined with a varied diet and they have other benefits as well (lower the incidence of colon cancer, better function of the gut). i would recommend you to take a supplement with just probiotic bacteria (2 billion bacteria per gram) in it because yogurts that claim to have probiotics in them have very low concentrations so they don't really work. one of the most well known is the Lactobacillus acidophilus. another thing that i would strongly recommend is that you don't take any of the small bottle drinks claiming to have live culture in them because they contain sugar and sugar kills bacteria, and lastly they also contain MODIFIED starch; all of them.

How do plants, humans, and bacteria metabolize?
I just need a summary. Nothing TOO specific.
How do plants, humans, and bacteria metabolize?
Plants use CO2, water and light energy to produce sugars, and oxygen.
Humans ingest organic matter, and break it down into CO2 and water, using oxygen in the process.
There are many metabolisms used by different species in the Bacteria domain. Some can photosynthesize, some use aerobic respiration like animals.
Others can use anaerobic respiration, which uses different metals, such as iron or sulfur in place of oxygen.
+ many other pathways.
Reply:plant metabolize by taking in CO2 and sugar. this produces Oxygen
Humans take in sugar and turn it into energy
bacteria---Not sure sorry

What kills the staphylococco aureus bacteria definitively?
I did a search query on yahoo and found out that bleach does the trick. Now, if only we can inject it into the body, oh well.
Reply:Bleach is best. The Chlorine kills it.
Reply:I assume you are referring to a lesion of some sort that has an overgrowth of it? You don't want to put bleach on your skin... Now, if you are worried about it being on your hands, you should know that S. aureus is a "resident" of our skin... Meaning, it's just there all the time and you can't do much about it... and it doesn't harm us as long as we don't let it "take over"...
If you have a specific situation, you could use a surgical betadine scrub.. and a brush that has gone through an autoclave for sterilization to get rid of it from, for example, your hands.. (that's what surgeons and nurses do to disinfect their hands before surgery)
It really depends on what your situation is... If you want to kill it everywhere so that it's not on earth anymore... It's very unlikely to find something that will because there will always be a few that live through it.. Making the staph that much harder to kill bc they basically have small mutations that will keep them alive, and they will have daughter cells that are resistant to whatever you used as well, and so on and so on... Just like there are already drug resistant types of staph that people staying in the hospital for long periods of time can get.. Hope this helps..

Organisms such as fungi and bacteria that break down and absorb nutrients from dead plants or animals?
what are these?
Organisms such as fungi and bacteria that break down and absorb nutrients from dead plants or animals?
saprophytic organisms/saprophytes/decomposers
I di dsome research on wikipedia and i have learnt that a saprotroph(saprophyte or saprobe) is an organism that obtains its nutrients from non-living organic matter, usually dead and decaying plant or animal matter, by absorbing soluble organic compounds. Since saprotrophs cannot make food for themselves, they are considered a type of heterotroph. Where as a decomposer (or saprotrophs) are organisms that consume dead plants and animals, and, in doing so, carry out the natural process of decomposition. Like herbivores and predators, decomposers are heterotrophic, meaning that they use organic substrates to get their energy, carbon and nutrients for growth and development. Decomposers use deceased organisms and non-living organic compounds as their food source.
So basically they are the samething so use which ever one you wish

Can parasites and other waterborne bacteria in home aquariums be harmful to humans?
I've heard that there is a risk of being infected with ailments from maintaining a home aquarium.
Can parasites and other waterborne bacteria in home aquariums be harmful to humans?
the only way it could become dangerous to people is if you never clean it, don't use a filter, and let dead fish build up in the tank without removing them. Then the water might make you sick.
Reply:Yes. Especially to children and the elderly.
Reply:Yes, make sure your tank is cleaned regularly. If you have kids, don't let them play with the water. A clean tank is not a health risk.
Reply:Children, elderly people, and especially people with a weakened or low immune system, such as people on immuno despressant drugs, are susceptible to bacteria from a fish tank, most usually salmonella.
Reply:yes you actually can catch things from having cuts or open sores on your hands and putting them in the tank. The home aqaurium is a varible cesspool of bacterias and such. Parasites are not such a problem as long as you don't drink the water.
Reply:yes, if proper care is not used. if handling a sick tank, always wash hands (and arms if wet) immediately with warm soap and water. Fish can get diseases similar to tubercolosis, a very dangerous disease to humans.
Reply:yes, some can be.

What kinds of metabolism does bacteria use?
Plz put down source and proof.
What kinds of metabolism does bacteria use?
well, it's autotrophy, or chemotrophy, or some other phrases, means produce own chemical food
inorganic compounds are oxidized directly (without using sunlight) to yield energy (e.g., NH3, NO2-, S2, and Fe2+). it also requires energy for CO2 reduction, like photosynthesis, but no lipid-mediated processes are involved.
other than that, some bacterias do photosynthesis, chemosynthesis, and some are saprophytic and parasitic as well
