About Vibrio

General information:
Gram-negative, part of the family Vibrionaceae, which is also includes the genera Aeromonas and Plesiomonas.
V. cholerae is one of several medically important species, the others being V. parahaemolyticus and V. vulnificus.
V. cholerae is well recoginzed and extensively studied as the causative agent of the human intestinal disease cholera. The disease occurs at the mucosal surface, with no invasion by the microbe into deeper tissue, and the disease symptons are primarily due to the action of a sigle molecule, the cholera toxin.
