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.
Vibrio is a genus of Gram-negative bacteria, possessing a curved-rod (comma) shape, [1] [2] [3] [4] several species of which can cause foodborne infection or soft ...
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]
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 ...
As mentioned above, Vibrionaceae bacteria are in symbiosis with many marine organisms. [3] In the case of the puffer fish, and other marine organisms harboring TTX-producing Vibrionaceae, the symbiosis is an ancient and powerful one, providing protection against predation for the marine organisms that harbor these bacteria, while providing the ...
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]
By the 20th century "vibrion" came to be used as a general term for motile microorganisms with an elongated, wormlike shape associated with pathogenic illnesses such as cholera and tetanus. It was also incorporated in the names created for several bacteria by microbiologists at the time, such as in the name " Vibrion septique " from a 1922 ...
Some bacteria, called vibrio, are shaped like slightly curved rods or comma-shaped; others can be spiral-shaped, called spirilla, or tightly coiled, called spirochaetes. A small number of other unusual shapes have been described, such as star-shaped bacteria. [44]
