Pathogenic and pandemic <i>Vibrio parahaemolyticus</i> detection in fish and shellfish isolates

Abstract

In this study, one hundred and seventy isolates of <i>V. parahaemolyticus</i> from marine water fish and shellfish were analyzed by PCR for the presence of <i>tdh</i> and <i>trh</i> virulence genes and <i>toxRS</i> region pandemic gene. The <i>tdh</i> and <i>trh</i> gene was detected in 55.3% and 0.59% of isolates respectively; whereas, <i>toxRS</i> region was detected in 34.1% isolates. Findings of the present study suggested that marine water fish and shellfish isolates of <i>V. parahaemolyticus</i> harbor pathogenic as well as pandemic genes which may serve as source for clinical infection through food chain.
