Study Notes
Shigella dysenteriae
- Shiga toxin is a virulence factor of Shigella dysenteriae
- The characteristic clinical sign of Shigella dysenteriae infection is bloody diarrhea
Pathogenic Organisms
- Escherichia coli (E. coli) is responsible for urinary tract infections, Summer diarrhea, and infantile diarrhea
Proteus spp.
- The urease enzyme produced by Proteus spp. breaks down urea to ammonia, which raises the urinary pH and helps the bacteria to create a protective environment
Transmission of Shigella
- Shigella spp. is transmitted through the fecal-oral route, often via contaminated food or water
