Principle And Interpretation

Members of the genus Vibrio are facultative anaerobes capable of both respiratory and fermentative metabolism. The natural habitat for Vibrio species is aquatic, in both fresh water and salt water.

Gelatin Agar is formulated in accordance with APHA (1) for the cultivation and characterization of Vibrio species from foods and faeces. Clinical specimens must be obtained early in the disease as possible because the duration of excretion of the pathogen is short.
