What are sympotoms of Pathogenic Bacteria?

you mean characteristics of pathogenic bacteria? this is a pretty broad category of microorganisms that cause disease and infections. there are two main types of bacteria -- gram positive and gram negative. they cause different infections and have different physical characteristics (for example, gram negative, when stained with special substance, becomes a pinkish color; it also has a thinner peptidoglycan layer). if you want more info, add more details =)
