Prevalence of Vibrio spp. in marine shrimp (Paeneus monodon) caught off the Persian Gulf coast of Iran

Vibrios are human pathogens that are widely distributed in the marine environments. Those organisms are frequently isolated from a variety of raw seafood’s. Consumption of raw or undercooked sea food contaminated with some of Vibrio species، may lead to development of acute gastroenteritis and clinical specimens. The present study aimed at determining the contamination of shrimps caught off the south coast of Iran. A total 120 samples of fresh shrimp collected from marine shrimps (Paeneus monodon) were tested for possible presence of Vibrio species by cultural and biochemical analysis. Vibrio spp. was detected in 26. 7% of the samples analyzed in this study. Among Vibrio isolates، Vibrio alginolyticus was the species most frequently detected (43. 6%)، followed by Vibrio parahaemolyticus (34. 4%)، Vibrio vulnificus (9%)، Vibrio cholera and Vibrio orientalis (6. 5%). The results confirmed the need for a specific shrimp inspection plan to detect the presence of Vibrio species in order to eliminate public health risks associated with shrimp consumption.
