Vibrio cholerae is a natural inhabitant of aquatic ecosystems. Some strains of V. cholerae can colonize human hosts and cause cholera, a profuse watery diarrhea. The major pathogenicity factors and virulence regulators of V. cholerae are encoded either in mobile genetic elements acquired in the environment (e.g., pathogenicity islands or lysogenic phages) or in the core genome. Furthermore, V. cholerae induces virulence in response to taurocholate only after exiting from the biofilm. Our data suggests a model in which V. cholerae ingested as a biofilm has co-opted the host-derived bile salt signal to sequentially detach from the biofilm and go on to activate virulence, which is further promoted by the synergistic effects of physiological levels of Ca2+.

The resistance-nodulation-division (RND) family efflux systems are ubiquitous transporters that have been extensively studied due to their ability to efflux a broad range of xenobiotic substrates. There is increasing evidence to suggest that the RND efflux systems have physiological roles beyond xenobiotic resistance to include pathogenesis and cellular stress responses. Abstract: Vibrio cholerae is a Gram-negative bacterium and the causative agent of cholera. The bacteria infect humans via contaminated water and food, and colonize the . Vibrio cholerae cytolysin (VCC) is a potent membrane pore forming protein toxin secreted by many pathogenic strain of the blogger.comae. In its membrane pore-formation mode of action, VCC belongs to the.

Cholera is an acute intestinal disease. The disease is caused when a person consumes food or water contaminated with the bacterium, Vibrio cholerae (Barua and Greenough 1). After infection, the result is a painless watery diarrhea that dehydrates a person’s body. disease cholera, Vibrio cholerae. Transposon insertions in the tryptophanase gene contained within the genomes of two en-vironmental strains of V. cholerae were shown to result in diminished biofilm formation by each mutant, and supplemen-tation of indole in the growth medium was able to complement. Indole has been proposed to act as an extracellular signal molecule influencing biofilm formation in a range of bacteria. For this study, the role of indole inVibrio choleraebiofilm formation was examined. It was shown that indole activates genes involved in vibrio polysaccharide (VPS) production, which is essential blogger.comae.
