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 ...
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]
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.

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]
Bacteria-caused illnesses hinge on the bacteria's physiology and their ability to interact with their environment, including the ability to shapeshift. Researchers discovered a protein that allows the bacterium Vibrio cholerae to morph into a corkscrew shape that likely helps it twist into — and then escape — the protective mucus that lines ...
Cholera is caused by a number of types of Vibrio cholerae, with some types producing more severe disease than others. [2] It is spread mostly by unsafe water and unsafe food that has been contaminated with human feces containing the bacteria. [2] Undercooked shellfish is a common source. [9] Humans are the only known host for the bacteria. [2]
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]
