- Virulence factors
- Mediated by 2 enterotoxins
- Heat-labile (LT)
- Increases intracellular cAMP in gut mucosa cells by activating Gs/adenylate cyclase
- Very similar to cholera toxin
- Heat-stabile (ST)
- Increases cGMP by activating guanylate cyclase
- Both cause increased secretion of fluid/ions to cause diarrhea
- Heat-labile (LT)
- Mediated by 2 enterotoxins
- Transmission
- Occurs in travelers to developing countries (traveler’s diarrhea)
- Presentation
- Watery Diarrhea
- Abdominal cramping, nausea, vomiting
