Abstract
Association of Vibrio parahaemolyticus with market freshwater fish samples in and around Kolkata and their mutagenicity to chloramphenicol was investigated. Vibrio parahaemolyticus was isolated in 14% of freshwater fish samples possibly because of cross-contamination due to mishandling of freshwater fishes along with brackishwater and/or marine fishes. The mutation frequency of oxytetracycline resistant V. Parahaemolyticus strains was found to be high (1.13 × 10-9 - 1.00 × 10-9) compared to that of the strains susceptible to antibiotics (3.16 × 10-10 - 2.39 × 10-10), which is a cause of concern from public health point of view.
