Molecular characterization of enterotoxin producing and antibiotic resistant  Staphylococcus aureus isolates from respiratory infected cotton industries labours from Salem district, Tamil Nadu


Hemalatha P., Martin, P., Rajasekarapandian, M. and Senthilkumar, B.


A total of 26 Staphylococcus aureus isolates from the respiratory infected cotton industries labours were subjected to the multiplex PCR amplification to detect Staphylococcal enterotoxins encoding gene. S. aureus isolates showed the presence of enterotoxins encoding gene i.e.See (50%), Sec (11.5%), Sea (8%) and Sed (8%). This present study also revealed that 69.2% of S. aureus isolates harboring MecA gene confers resistance to methicillin antibiotic. About 50% of S. aureus isolates were found to carry MupA gene confers resistance to Muprocin antibiotic. This study concludes that it is necessary to control the respiratory infections by using appropriate antibiotics in order to avoid spreading of infection as well as spreading antibiotic resistant and public health issues.
