Vibrio cholerae is a species of Gram-negative, facultative anaerobe and comma-shaped bacteria. [1] The bacteria naturally live in brackish or saltwater where they attach themselves easily to the chitin -containing shells of crabs, shrimp, and other shellfish.
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]
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 ...
Vibrio vulnificus is a species of Gram-negative, motile, curved rod-shaped (vibrio), pathogenic bacteria of the genus Vibrio. Present in marine environments such as estuaries, brackish ponds, or coastal areas, V. vulnificus is related to V. cholerae, the causative agent of cholera. [3] At least one strain of V. vulnificus is bioluminescent. [4]
While often reported that the T6SS was discovered in 2006 by researchers studying the causative agent of cholera, Vibrio cholerae, the first study demonstrating that T6SS genes encode a protein export apparatus was actually published in 2004, in a study of protein secretion by the fish pathogen Edwardsiella tarda. [1] [2] [3]
A characteristic of the family is the broad host range susceptible to infection by vibrios. Pathogens of man, other than V. cholerae, include V. parahaemolyticus, a cause of gastroenteritis and V. vulnificus that can lead to acute and fatal septicaemia.
When some otherwise non-hemolytic bacteria, such as strains of the cholera-causing bacteria Vibrio cholerae, are plated on blood agar, no clearings are observed surrounding isolated colonies, but the blood surrounding larger areas of growth turns green. This process, called hemodigestion, is caused by the metabolic by-products of the bacteria ...
