Incidence of multi drug resistant coagulase-negative Staphylococci from seafood samples, Veraval, Gujarat

Abstract

In earlier days, Coagulase-negative Staphylococcus (CoNS) were considered as a non-pathogenic or opportunistic pathogen, and much attention was not given to them. Recently, due to the transfer of resistant genes from non-pathogen to opportunistic pathogens leads to a severe illness in human clinical cases. In most of the food materials, CoNS with multi-drug resistance (MDR) were reported. But, very scant information is available on the different proportions of the CoNS and its resistance pattern to different classes of antibiotics. In the present study, a total of 31 CoNS consists of six different species like S. warneri (12), S. haemolyticus (6), S. hominis (4), S. saprophyticus (3), S. simulans (3) and S. xylosus (3) were isolated from 31 seafood samples including fin fishes, shrimp, lobster and octopus, and identified using API biomerieux strips. The antibiogram results of high resistance rates against gentamicin (70.90%), azithromycin (64.50%) and tigecycline (32.20%) were detected. Thus, the findings suggest that CoNS in seafood samples can have a potential role as a reservoir for antimicrobial resistance and its transfer.
