V. cholerae is a highly motile, comma shaped, gram-negative rod. The active movement of V. cholerae inspired the genus name because "vibrio" in Latin means "to quiver". [29] Except for V. cholerae and V. mimicus, all other vibrio species are halophilic. Initial isolates are slightly curved, whereas they can appear as straight rods upon ...
CAI-1 has no readily apparent recordable discovery date, but some of the earliest studies on autoinducers within and the quorum-sensing nature of V. cholerae was done by the Microbiology department of Harvard Medical school. [1] Prior to the study of V. cholerae, researchers obtained data from a close relative, Vibrio harveyi.
Cholera (/ ˈ k ɒ l ər ə /) is an infection of the small intestine by some strains of the bacterium Vibrio cholerae. [4] [3] Symptoms may range from none, to mild, to severe. [3]The classic symptom is large amounts of watery diarrhea lasting a few days. [2]
Cholera is caused by ingesting a bacteria known as Vibrio cholerae. It's found in contaminated water and food, explains Ivers, which then produces a toxin in the small intestine that leads to the ...
Thiosulfate–citrate–bile salts–sucrose agar, or TCBS agar, is a type of selective agar culture plate that is used in microbiology laboratories to isolate Vibrio species. [1] TCBS agar is highly selective for the isolation of V. cholerae and V. parahaemolyticus as well as other Vibrio species. Apart from TCBS agar, other rapid testing ...
De and colleagues also published highly cited pioneering studies on V. cholerae action on the intestinal membrane. [4], [5], [8] The 1953 paper “An experimental study of the mechanism of action of Vibrio cholerae on the intestinal mucous membrane” [4] is De’s most-cited paper, cited 340 times until August 1986. De’s most-cited paper has ...
One of the candidates from this study, IGR 7, was shown to be involved in carbon metabolism and later renamed MtlS RNA. Other sRNAs identified in V. cholerae through genetic screens and computational methods include Qrr RNA, Vibrio regulatory RNA of OmpA, MiX sRNA, Vibrio cholerae ToxT activated RNAs, foR RNA, and VqmR sRNA.
Cholera toxin (also known as choleragen and sometimes abbreviated to CTX, Ctx or CT) is an AB5 multimeric protein complex secreted by the bacterium Vibrio cholerae. [1] [2] CTX is responsible for the massive, watery diarrhea characteristic of cholera infection. [3] It is a member of the heat-labile enterotoxin family.
