Prevalence of Staphylococcus aureus in Shrimps in Tehran during 2013
AbstractBackground: During fishing and transport, preservation and quality of fish products are important as well as storage to prevent the growth of pathogenic and toxin producing bacteria. Staphylococcus aureus is one of the most common causes of sea food-borne diseases worldwide due to contamination of food by preformed enterotoxins. The aim of this study was to compare the prevalence and contamination of S. aureus in marine and farmed shrimps in Tehran fishery center.Methods: A total of 300 samples, including 150 marine, 150 farmed shrimps were selected during September 2013 to December 2014. Isolation and identification of S. aureus from isolated samples were carried out according to conventional methods, and antibiotic susceptibility test was performed by modified Kirby-Bauer disc diffusion method. Results: The results of this study showed that 30% of marine and 20% off armed shrimps were contaminated with S. aureus. The highest resistance was observed with penicillin and ampicillin, whereas 100% were sensitive to vancomycin, clindamycin, ciprofloxacin, and rifampin. Conclusion: Due to relatively high contamination of shrimp by S. aureus more attention should be given during processing and manufacturing.
