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:

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]
