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 ...
V. cholerae is generally transmitted by contaminated water. [3] Pathogenic Vibrio species can cause foodborne illness (infection), usually associated with eating undercooked seafood. [18] When ingested Vibrio bacteria can primarily result in watery diarrhea along with other secondary symptoms. [19]
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]
CTXφ is generally present and integrated into the genome of the V. cholerae bacterium, and more rarely in a virion from outside the bacterium. While integrated into the bacterial genome, CTX prophages are found on each of the two chromosomes (in the O1 serogroup of V. cholerae) or arranged in tandem on the larger chromosome (in the El Tor biotype of V. cholerae). [2]
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]
Vibrio cholerae str. El Tor El Tor is a particular strain of the bacterium Vibrio cholerae , the causative agent of cholera . Also known as V. cholerae biotype eltor, it has been the dominant strain in the seventh global cholera pandemic .
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 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.
