摘要

Introduction: Biofilm producing Staphylococcus aureus is known as one of the majorcausative agents of infections, failure of implanted devices and persistent infectionamong hospitalized patients. The aim of the present study was to determine thefrequency of biofilm producing S. aureus isolates amongst the clinical specimens.Methods: This cross-sectional study was conducted during 2012 to 2013 in twoteaching hospitals in Shiraz, southwest of Iran. Totally, 345 S. aureus isolates fromvarious clinical specimens were included. Biofilm producing isolates werephenotypically detected using Congo Red Agar (CRA) and genotypically by PCRassay for the icaA and icaD genes.Results: Of the 345 S. aureus isolates, 42.3% were methicillin-resistant S. aureus(MRSA) and subsequently 57.7% were methicillin susceptible isolates. The results ofCRA plates showed that 77 (52.7%) and 74 (37.2%) of MRSA and MSSA werebiofilm producing isolates. The frequency of icaA/D genes among MRSA and MSSAisolates was 127 (87%) and 167 (83.9%), respectively.Conclusion: Such a high rate of icaA/D harboring S. aureus among clinical isolatessuggest the risk for establishing persistent infections in the hospital settings.
