∙ 11y agoSome bacteria are harmful, and these bacteria are called pathogens; common examples include Salmonella typhus and E. coli O157:H7. However, many bacteria are neutral to humans - they do not help us, but they do not cause disease. There are thousands of species of bacteria living in the soil, on and in plants and throughout the world that never impact humans directly. Also, there are some classes of bacteria that are helpful to humans, including the microbiomes in our intestines that help us digest our food and the microbiome on our skin that protects us from all sorts of nasty skin infections.

∙ 8y agoIt depends of what kind of bacteria it is, if it is almost 99% than it is good but if it is below 50% than it is bad and can either make someone sick or it makes them die.
