Thiosulfate-citrate-bile salts-sucrose (TCBS) Agar

Description

Thiosulfate Citrate Bile Salts Sucrose Agar (TCBS Agar) is used for the selective isolation of Vibrio cholera and Vibrio parahaemolyticus from a variety of clinical and nonclinical specimens.

TCBS is the primary plating medium universally used for the selective isolation of vibrios that cause cholera, diarrhea and food poisoning. It was developed by Kobayashi et al., who modified the selective medium of Nakanishi. The combination of alkaline peptone water and TCBS Agar is used in many procedures for the isolation of V. cholerae and other Vibrio species from feces.
