No, not all bacteria is classified as being harmful.For example, the bacteria found in yogurt is the good bacteria that helps rid the body of infection.And the bad bacteria is a series of strains that are harmful. To name a few would be like menningitis,salmonella, and steptococcus which can make a person very ill...in worse cases fatal at times.

There are many bacteria that function along with the human body . For instance there are roughly 500 species of bacteria that live in our mouths, and there are many different bacteria that help us digest and protect us from the harmful pathogens. The bacteria that effects us humans physically is the manor in which the bacteria evolve and mutate while being within the human body and either attached to certain cells and organs.

usually nothing. First of all, most bacteria are not harmful. The vast majority do not cause disease in us.
Bacteria are sometimes harmful to people because of the chemical metabolism byproducts they produce, or because they "infect" a tissue. In other words, from the bacteria's perspective, when they infect us, they work their way into and live in a specific tissue of ours and do their thing. Our bodies react negatively to their presence, sending out white blood cells, etc.

Not all bacteria are harmful. You have hundreds of types in your body that are neutral, or even essential.
Some bacterias do attack the human body due to their genetic makeup.

It is the enzymes created by bacteria that can disrupt your normal bodily functions. Some bacteria are more harmful than others. That is why there are 'narrow' and 'wide' spectrum anti-biotics.
