| Shiga bacillus | A species of gram-negative, facultatively anaerobic, rod-shaped bacteria that is extremely pathogenic and causes severe dysentery. Infection with this organism often leads to ulceration of the intestinal epithelium. (12 Dec 1998) |

| Shiga toxin | <protein> Bacterial toxin from Shigella dysenteriae that blocks eukaryotic protein synthesis. See: Shiga like toxins. (18 Nov 1997) |
