Overview
Shigellosis is usually a foodborne or waterborne illness caused by an infection with Shigella species. Shigella is a gram-negative, non-motile, facultatively anaerobic, non-spore-forming rod.
Causes
Etiologic Agent
Shigellosis is usually a foodborne or waterborne illness caused by an infection with Shigella species.
- There are 4 Shigella species that are responsible for development of Shigellosis:
- Serogroup A: S. dysenteriae (12 serotypes)
- Serogroup B: S. flexneri (6 serotypes)
- Serogroup C: S. boydii (23 serotypes)
- Serogroup D: S. sonnei (1 serotype)
Structure
- Shigella is a gram-negative, non-motile, facultatively anaerobic, non-spore-forming rod.[1]
- Shigella is closely related to E. coli, where both organisms are thought to be derived from similar vector plasmids. Unlike E. coli, Shigella cannot ferment lactose or decarboxylate lysine.[1]
