ABSTRACT

The production of a family of haemolysins-thermostable direct haemolysin (Vp-TDH) and Vp-TDH related haemolysin (Vp-TRH) has been reported in clinical isolates of Vibrio parahaemolyticus. The work was aimed to study the occurrence of V. parahaemolyticus, in fishes sold in the domestic markets of Gujarat and incidence of Vibrio parahaemolyticus. A total of 155 fish samples comprising fin fishes and prawns were collected from various fish markets in and around Anand (Gujarat), India. Eighteen samples were found to be positive for V. parahaemolyticus. Pathogenicity of the isolates was confirmed by Kanagawa phenomenon. Antibiogram revealed 88% isolates to be sensitive to chloramphenicol, followed by 72.22% to ciprofloxacin and 66.66% to cephalothin. Multiple antibiotic resistance index was found to be 0.4, indicating higher resistance acquired by the isolates. The present study demonstrated the need to adopt marine fish safety measures for the products meant for human consumption.
