Incidence of Aeromonas hydrophila and Plesiomonas shigelloides in Seafoods

Abstract

The present study was conducted to investigate the incidence of the pathogens Aeromonas hydrophila and Plesiomonas shigelloides in 700 seafoods (400 raw fish, 100 raw shrimps and 200 raw mollusks) collected from retailers. Isolations were performed by conventional culture methods. The isolates were also confirmed by polymerase chain reaction (PCR) assays. A. hydrophila and P. shigelloides were detected in 5.71% and 0.86% seafood samples, respectively. The highest rate of A. hydrophila (15%) was found in shrimp samples. P. shigelloides were only isolated from fish samples. The study is showed that effective methods to eliminate the Aeromonas and Plesiomonas species are needed.
