List of Diseases caused by Bacteria


Bacteria is a large domain that consists of single-celled prokaryotes. They can be found in virtually all environments (aquatic, terrestrial, the Arctic, etc.) around the world where they may exist as free-living organisms, parasites, or in symbiosis with other organisms in their surroundings.

While it's estimated that there are over one (1) trillion species of bacteria (the vast majority have not yet been identified), only about 5 percent of these are said to cause diseases.




The following is a list of diseases caused by bacteria:
