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 ...

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]
Gram stain (Gram staining or Gram's method), is a method of staining used to classify bacterial species into two large groups: gram-positive bacteria and gram-negative bacteria. It may also be used to diagnose a fungal infection. [1] The name comes from the Danish bacteriologist Hans Christian Gram, who developed the technique in 1884. [2]
Pasteurella multocida is a Gram-negative, nonmotile, penicillin-sensitive coccobacillus of the family Pasteurellaceae. [1] Strains of the species are currently classified into five serogroups (A, B, D, E, F) based on capsular composition and 16 somatic serovars (1–16).

A number of human pathogens belong to this class, including Yersinia pestis, Vibrio cholerae, Pseudomonas aeruginosa, Escherichia coli, and some species of Salmonella. The class also contains plant pathogens such as Xanthomonas axonopodis pv. citri (citrus canker), Pseudomonas syringae pv. actinidiae (kiwifruit Psa outbreak), and Xylella ...
It is a small, Gram-negative bacillus with bipolar staining by Wayson stain. In animals, it can originate in fulminant septicaemia ( chicken cholera ), but is also a common commensal . Until taxonomic revision in 1999, [ 3 ] Mannheimia spp. were classified as Pasteurella spp., and infections by organisms now called Mannheimia spp., as well as ...
