Kingdom: Bacteria
Phylum: Proteobacteria
Class: Gamma Proteobacteria
Order: Vibrionales
Family: Vibrionaceae
Genus: Vibrio
Species: V. cholerae
Shape & Gram-stain
• Gram-negative
• Comma-shaped bacterium
• Polar flagellum that bacteria uses for
movement.
Additional Characteristics
• Facultative anaerobe, which
means the bacteria can
survive either with or
without oxygen
• The genes of a virus have
become integrated into the
bacterial genome and made
the bacteria pathogenic
• Some serotypes have
capsules while others do not
• chemoheterotroph
History
• Filippo Pacini discovered the bacteria in 1854
• Not widely known until Robert Koch
• The bacteria thrives in a water ecology,
particularly surface water.
Health-related issues
• Causes cholera, an acute, diarrheal illness that can
result in severe dehydration
• A person may get cholera by drinking water or eating
food contaminated with the bacteria.
• Casual contact with an infected person is not a risk for
becoming ill
• After ingested, the bacteria travels to the small
intestine, where it multiplies. Then it produces a toxin
that causes diarrhea.
• Treated by immediate replacement of the fluid and
salts lost through diarrhea (oral rehydration solution)
