Gram-negative, curved bacteria
- V. cholerae is a gram-negative, curved bacteria which looks like little red or pink comma-shapes on a gram stain. It’s positive for oxidase and grows in alkaline media. It has pili and a single polar flagellum, kind of like a tail, at one end which it uses for movement through the gastrointestinal tract.

May 1, 2024 · Cholera is an acute secretory diarrhea caused by toxigenic strains of Vibrio cholerae, a gram-negative, comma-shaped bacterium. Cholera is characterized by severe, acute, large-volume, watery diarrhea resulting in rapid dehydration and is associated with high mortality if not treated promptly.

Vibrio cholerae is a species of Gram-negative, facultative anaerobe and comma-shaped bacteria. The bacteria naturally live in brackish or saltwater where they attach themselves easily to the chitin-containing shells of crabs, shrimp, and other shellfish.
Because of their rapid growth and characteristic colonial morphology, V cholerae can be easily isolated and identified in the bacteriology laboratory, provided, first, that the presence of cholera is suspected and, second, that suitable specific diagnostic antisera are available. The vibrios are completely inhibited or grow somewhat poorly on ...
Vibrio cholerae is a facultative pathogen that has an environmental reservoir in aquatic ecosystems and a pathogenic phase in the human small intestine. It produces cholera toxin in the small...

Apr 16, 2015 · Biofilms of Vibrio cholerae, the causative agent of cholera, have an important role during the aquatic and intestinal phases of the bacterial life cycle, conferring greater resistance to...
Nov 2, 2020 · Vibrio cholerae, the pathogenic bacterium responsible for the diarrheal disease cholera, adopts a characteristic “comma”-shaped cell morphology. Here we show that the intracellular signaling molecule, cyclic di-GMP, drives curved V. cholerae to adopt a straight cell morphology that is advantageous to a sessile biofilm lifestyle, while ...
