Sep 30, 2020 · A total of 524 genes are differentially expressed in classical and El Tor strains, the two biotypes of V. cholerae serogroup O1. Within the host, many immune and biological factors are able to induce genes that are responsible for survival, colonization, and virulence.
Vibrio cholerae is a facultative pathogen that has an environmental reservoir in aquatic ecosystems and a pathogenic phase in the human small intestine. It produces cholera toxin in the small...
Nov 14, 2007 · Vibrio cholerae, the causative agent of cholera, employs quorum sensing to repress virulence factor expression at high cell density. The nature of one of the major...
The ability of V. cholerae to colonize and cause disease in hosts requires production of a number of virulence factors during infection. The two major viru-lence determinants of V. cholerae are encoded by two separate genetic elements.
Oct 29, 2021 · Vibrio is an ubiquitous bacterium that is widely present in various aquatic and marine habitats; among the more than 100 species of Vibrio described, about 12 can cause human infections, while other Vibrio lead to marine animal infections.
Feb 5, 2020 · Vibrio cholerae, the causative agent of the severe diarrheal disease cholera, has evolved signal transduction systems to control the expression of virulence determinants.
Dec 5, 2012 · A model for V. cholerae infection involves motile bacteria attaching to the intestinal cell surface, after which they upregulate virulence factor expression and downregulate motility. The flagellar regulatory hierarchy also influences virulence gene expression in V. cholerae through the quorum sensing system.
