Parahaemolyticus is the leading causal agent of human acute gastroenteritis following the consumption of raw undercooked or mishandled marine products. Compared with TCBS agar CAV provided higher.

Vibrio parahaemolyticus is one of the important foodborne pathogens is of public health concern due to the emergence of pandemic strains causing disease outbreaks worldwide. The differentiation of V parahaemolyticus from other pathogenic species of Vibrio is based mainly on salt tolerance Voges-Proskauer reaction fermentation of sucrose and growth at 43C. TCBS agar is green when prepared.

Aside from Vibrio parahaemolyticus Vibrio vulnificus also produces green colonies because they do not ferment sucrose. Sucrose nonfermenting organisms such as V. Suspicious colonies for further testing should be subcultured to a noninhibitory medium such as triple sugar iron agar TSI.

Vibrio parahaemolyticus is a Gram-negative halophilic bacterium that is found in estuarine marine and coastal environments. Suspicious colonies for further testing should be subcultured to a. TCBS Agar Vibrio Selective Agar Thiosulfate Citrate Bile Sucrose Agar Thiosulfate Citrate Bile Sucrose Agar pr oposed by NAKANISHI 1962 modified by KOBAYASHI et al.

V SUMMARY AND EXPLANATION Vibrio species are most widely recognized for their role in human intestinal infections and cholera and V. Vibrio parahaemolyticus frequently is isolated from seafood environmental and clinical samples using alkaline peptone water APW and thiosulfate citrate bile-salts sucrose TCBS agar. Recovery of Vibrio is greater than with TCBS agar even if using an enrichment broth.

Vibrio cholerae produces yellow colonies in TCBS agar whereas Vibrio parahaemolyticus. Comparative performance of TCBS and TSA for the enumeration of trh Vibrio parahaemolyticus by direct colony hybridization. Parahaemolyticus produce green to blue-green colonies as it does not ferment sucrose.

TCBS Agar is used for the isolation of Vibrio cholerae and other enteropathologic Vibrio in particular Vibrio parahaemolyticus in fish seafood and biological samples of animal origin. In TCBS agar parahaemolyticus always occurs as a green colony but with some minor differences in pigmentation. Parahaemolyticus in foods uses TCBS.
