Nickname: Shigella

Morphology: Gram-negative rod

Habitat: Humans and other large primates are the only carriers of this bacteria.

Disease or illness: Even a small number of these bacteria can make a person very sick. Shigella causes severe diarrhea with blood and pus in the stools.

Who is at risk: Any person who allows the bacteria to enter their body by eating contaminated food or drinking contaminated water.

Avoidance techniques: Wash hands frequently, especially after using the toilet, after changing diapers, and before preparing foods or beverages; persons with diarrhea should not prepare food for others; avoid drinking swimming pool water.
