Any of a group of aquatic, comma-shaped bacteria in the family Vibrionaceae.Some species cause serious diseases in humans and other animals. They are gram-negative (see gram stain), highly capable of movement (with one to three flagella at one end), and do not require oxygen. Their cells are curved rods, single or strung together in S-shapes or spirals. Two species are of significance to humans: one causes cholera, the other acute bacterial diarrhea.* * *
▪ bacteria(genus Vibrio), any of a group of comma-shaped bacteria in the family Vibrionaceae. Vibrios are aquatic microorganisms, some species of which cause serious diseases in humans and other animals.Vibrios are microbiologically characterized as gram-negative, highly motile, facultative anaerobes (not requiring oxygen), with one to three whiplike flagella at one end. Their cells are curved rods 0.5 μm (micrometre; 1 μm = 10-6 metre) across and 1.5 to 3.0 μm long, single or strung together in S-shapes or spirals.Three species of vibrio are of significance to humans: V. cholerae is the cause of cholera, and V. parahaemolyticus and V. vulnificus both act as agents of acute enteritis, or bacterial diarrhea. V. anguillarum is found in diseased eels and other fishes.* * *
