TN AGAR

Members of the genus Vibrio are defined as gram-negative, asporogenous rods that are straight or have a single rigid curve. Three species of Vibrio, namely Vibrio cholerae , Vibrio parahaemolyticus and Vibrio mimicus are well documented human pathogens. V. cholerae , the type species of the genus Vibrio is the causative agent of cholera outbreaks and epidemics. V. cholerae can be differentiated from other Vibrio species except V. mimicus, because of its obligate requirement for sodium ions (Na+).TN Agar is formulated as per APHA for cultivation of Vibrio species from foods.

for isolation and cultivation of Vibrios from food samples
