shigellaAny of the rod-shaped bacteria that make up the genus Shigella, which are normal inhabitants of the human intestinal tract and can cause dysentery, or shigellosis. Shigellae are gram-negative (see gram stain), non-spore-forming, stationary bacteria. S. dysenteriae, spread by contaminated water and food, causes the most severe dysentery because of its potent toxin, but other species may also be dysentery agents.

| Changes in the worldwide epidemiology of shigellae species have been documented in the last two decades. No shigellae were resistant to ciprofloxacin in either country (Table 1). We report reduced sensitivity of enterobacteria to available antimicrobial agents in Zambia, with only 22% of nontyphoidal salmonellae and 6% of shigellae sensitive to SXT. |
