Vibrio Cholerae

Karolina Zapal

Classification

• 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)
