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.

What the difference between a bacteria and a virus?
A bacteria has some DNA fragments in them but a virus does not. I think
Reply:a virus doesn't have self-replication mechanism, needs a host cell to do that
Reply:Bacteria are much larger than a virus..
Reply:A bacterium is a living organizm with the ability to reproduce. A virus has neither of these characteristics. A virus replicates by injecting its' DNA sequence into a host cell which causes it to produce more viruses.
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.
Reply:Bacteria are living


Viruses are connecting link between living %26amp; non-living.Viruses are called living particles
Reply:A bacteria is a single celled organism with an internal metabolism, a virus is just a packet of genetic instructions in a protein casing.





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:Bacteria are cells with internal metabolism, they have a nucleus and very frequently flagellum. They are much bigger than viruses, these are simply DNA in a protein coat.
Reply:A virus can't reproduce by itself it needs a host cell - a bacteria can


a virus isn't classified as alive - a bacteria is


a virus has one set of genetic information - a bacteria has a main loop of DNA and several smaller loops called plasmids
Reply:Antibiotics do not work on a virus. They only work on bacterial infections.
Reply:bacteria - n : (microbiology) single-celled or noncellular spherical or spiral or rod-shaped organisms lacking chlorophyll that reproduce by fission; important as pathogens and for biochemical properties; taxonomy is difficult; often considered plants

virus -


n. pl. vi·rus·es





Any of various simple submicroscopic parasites of plants, animals, and bacteria that often cause disease and that consist essentially of a core of RNA or DNA surrounded by a protein coat. Unable to replicate without a host cell, viruses are typically not considered living organisms.





A disease caused by a virus.





Something that poisons one's soul or mind: the pernicious virus of racism.





Computer Science. A computer virus.
Reply:Bacteria multiply only in certain conditions i.e damp and warmth. But a virus can multiply inside organizisms, they genrally invade cells and take them over.
Reply:Bacterium is a living thing and is much much larger than viruses may be thousand times. Viruses are very small and can be crystallised which is a property of non living things. But they also have DNA type structures which is a property of living things. So they are 50:50. Some viruses can even cause diseases to bacteria as well.

Reply:A bacteria is killed by antibiotics, a virus is not.
Reply:Virus its an intracell parasit meanwhile bacteria isn't.


Virus barelly can be considered alive (there are a lot of dicussions about it) meanwhile bacterias are more organized beings. They have nucleo and a lot of other specialized structures meanwhile virus has only its DNA and specialized body.
Reply:You cant kill a virus with antibiotics as it multiplies and evolves a lot faster than bacteria. (Eg Common Cold)


Bacteria is treatable and lives in dirt and needs to be kept at a reasonable temperature for example body or room temperature etc.. (Eg Salmonella)
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:a virus can infect the cells of a biological organism it is different from a bacteria because it has a strand of DNA in it and every time it infects a person it adapt itself to the person


it cannot be cured by antibiotics you just have to let it run its course


a bacteria can be cured by antibiotics.it can multiply very fast
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 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
