Description and Significance

Describe the appearance, habitat, etc. of the organism, and why you think it is important.

Genome Structure

Vibrio cholera contains a 4.0Mbp genome, consisting of two circular chromosomes. There are a predicted 3,885 total genes.

Cell Structure, Metabolism and Life Cycle

Curved rod-shaped, singular polar flagellum. In the lab, optimal growth is in media containing an inorganic nitrogen source and a utilizable carbon source. In adequate media, the generation time is less than 30 min. Vibrio cholera are facultative anaerobes, preferring oxygenated environments to anaerobic. Optimal temperature for growth is 37degC, with growth possible between 10-43degC. The optimal pH is 7.6, growth possible at pH 5.0-9.6.

Ecology and Pathogenesis

Habitat; symbiosis; biogeochemical significance; contributions to environment.
If relevant, how does this organism cause disease? Human, animal, plant hosts? Virulence factors, as well as patient symptoms.
