Pathogenic bacteria are bacteria that can cause disease. This article deals with human pathogenic bacteria. Although most bacteria are harmless or often beneficial, some are pathogenic, with the number of species estimated as fewer than a hundred that are seen to cause infectious diseases in humans. By contrast, several thousand species exist in the human digestive system.

Pathogenic bacteria can be grouped into three categories on the basis of their invasive properties for eukaryotic cells (Fig. 7-4; Table 7-3). Although some bacteria (e.g., Rickettsia , Coxiella , and Chlamydia ) grow only inside host cells, others (e.g., Salmonella , Shigella , and Yersinia ) are facultative intracellular pathogens, invading ...

Pathogenic bacteria are a major cause of human death and disease and cause infections such as tetanus, typhoid fever, diphtheria, syphilis, cholera, foodborne illness, leprosy and tuberculosis. A pathogenic cause for a known medical disease may only be discovered many years after, as was the case with Helicobacter pylori and peptic ulcer disease .
