Dr. C. Manjula Vani Kiran, Dr. K. Veerender

Abstract :

Staphylococcus aureus is one of the important causes of community acquired and hospital acquired infections worldwide. Methicillin resistant Staphylococcus aureus is one of the major antibiotic resistant organisms. The present study was undertaken to determine the antibiotic sensitivity of Staphylococcus aureus isolates from various clinical samples and to evaluate the possible presence of MRSA. A total of 120 isolates of S. aureus which were isolated from various clinical samples were tested for methicillin resistance using the oxacillin disc diffusion test (1μg) and cefoxitin disc diffusion test (30μg). Disc diffusion method was also used to determine the susceptibility of strains to common antibiotics. 64(53.3%) isolates were found to be MRSA by the cefoxitin disc diffusion method and 63(52.5%) isolates were found to be MRSA by oxacillin disc diffusion method. . MRSA isolates were also highly resistant to other antibiotics that were tested
