Rawlings, Ruiz, Colwell. Pathogenicity is caused by serotypes O1 and the Gulf Coast El Tor strains. All right reserved. These toxins, when colonized in the small intestines, cause diarrhea, which in some cases can lead to dehydration, anuria, acidosis, and shock. Biofilm formation is dependent on the production of an exopolysaccharide (EPS).

These transitions are stressful and made even more difficult by pervasive virulent bacteriophages (phages). The success of Vibrio cholerae as a water-borne pathogen is dependent upon dissemination from its human host to the aquatic environment and a successful return to the small intestine where it elicits cholera. Optimal temperature for growth is 37degC, with growth possible between 10-43degC. Do you know which claims your medical scheme doesn't have to pay?
