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 ...
Cholera autoinducer-1 (CAI-1) is an autoinducer signaling molecule present in the bacterium Vibrio cholerae, which causes cholera. CAI-1 is known structurally as a (S)-3-hydroxytridecan and regulates expression of virulence factors.
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 ...
Inhabitants of fresh or salt water, several species are pathogenic, including the type species Vibrio cholerae, which is the agent responsible for cholera. Most bioluminescent bacteria belong to this family, and are typically found as symbionts of deep-sea animals. [1]
Vibrio cholerae is a non-toxic strain that can become toxic, producing cholera toxin, when it is infected with the phage CTXφ. Shigella dysenteriae, which produces dysentery has toxins that fall into two major groups, Stx1 and Stx2, whose genes are considered to be part of the genome of lambdoid prophages.
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]
One of the first pathogens observed by scientists was Vibrio cholerae, described in detail by Filippo Pacini in 1854.His initial findings were just drawings of the bacteria but, up until 1880, he published many other papers concerning the bacteria.
This group includes the phages Aeromonas salmonicida phage 56, Vibrio cholerae phages 138 and CP-T1, Bdellovibrio phage φ1422 and Pectobacterium carotovorum phage ZF40. [5] Their shared characteristics include an identical virion morphology, characterized by usually short contractile tails and all have genome sizes of approximately 45 kilobases.
