Abstract
Background: The emergence of Methicillin-resistant Staphylococcus aureus (MRSA) has posed a serious therapeutic challenge. It is responsible for a wide range of infections including superficial skin infections, food poisoning, osteomyelitis and septicemia. Aim of this study was to identify and to determine antibiotic susceptibility pattern of Staphylococcus aureus from various clinical samples. Materials and methods: Different clinical specimens were collected and processed for routine culture and antibiotic sensitivity test by standard microbiology techniques. Results: A total of 129 S. aureus strains were isolated from various clinical specimens out of which 84 (65.12%) were Methicillin Resistance Staphylococcus aureus (MRSA). 66(51.16%) S. aureus were obtained from indoor (IPD) patients. S. aureus was found higher in male than female. S. aureus was found highly resistant to Benzylpenicillin (94.57%) followed by ciprofloxacin (77.51%), Erythromycin (61.24%), and Cotrimoxazole (51.94%), Clindamycin (44.19%), and Gentamicin (17.05%). 1 (0.78%) of the isolates were resistance to Vancomycin and Linezolid. For urine isolates Nitrofurantoin was drug of choice. Conclusion: Methicillin resistant Staphylococcus aureus was found 65.12% of Staphylococcus aureus isolates. It was most common in males and hospitalized patients. Teicoplanin or Tigecyline seems to be drug of choice followed by Vancomycin, Linezolid, Tetracycline and Gentamicin. It would be helpful to formulating and monitoring the antibiotic policy and ensure proper empiric treatment.
