GELATIN PHOSPHATE SALT AGAR (GPS AGAR)

Description

Vibrio cholerae is a non-halophilic Vibrio, which cannot grow in media with a concentration of sodium chloride greater than 5-6% and is able to grow in media lacking NaCl. Human disease is associated with ingestion of contaminated water or food. V.cholerae is the etiological agent of a secretory diarrhea spread by the faecal-oral route. The most critical virulence factor of V. cholerae is CT, which is responsible for the main symptom of the cholera disease. Gelatin Phosphate Salt Agar is a non-selective medium formulated as per APHA and used for plating enrichment cultures of V. cholerae obtained from seafoods or vegetables.
