Title

PREVALENCE AND PATTERN OF ANTIBIOTIC SENSITIVITY OF METHICILLIN-SENSITIVE AND METHICILLIN-RESISTANT STAPHYLOCOCCUS AUREUS IN SHIRAZ-IRAN

Abstract

 Background: There is a growing concern about the rapid rise in resistance of STAPHYLOCOCCUS AUREUS to antimicrobial agents.Objective: To determine the PREVALENCE and pattern of antibiotic sensitivity among methicillin-resistant and -sensitive S.aureus in Shiraz, south of Iran.Methods: One hundred and six S. aureus isolates from patients with staphylococcal infections were collected. The isolates were screened for methicillin-resistance by minimum inhibitory concentration (MIC) determination and agar screen plate. Detection of acquired resistance was accomplished by addition of a b -lactamase inhibitor to the test media. Tolerance was detected by determination of minimum bactricidal concentration (MBC)/MIC ratio. Results: The frequency of intrinsic-resistant S. aureus was 33.0% (90% in isolates from burn unit patients). Acquired-resistant and tolerant isolates comprised 4.7% and 0.9% of all isolates respectively. None of the isolates showed MOD-type resistance [for "modified" penicillin binding proteins (PBPs)]. The pattern of resistance to 13 antibiotics were determined by disk diffusion method. None of the intrinsic-resistant isolates were resistant to vancomycin or rifampin but the frequency of resistance to other compounds was high. The methicillin-sensitive and acquired-resistant isolates were highly sensitive to all tested antibiotics except penicillin. Conclusion: In this study, methicillin-resistance proved to be a useful marker in selecting appropriate antimicrobial agents for treatment of infections caused by S. aureus. Changing pattern of resistance of S.aureus makes its periodic surveillance (each 3 to 4 years once) mandatory.
