Sensitivity Pattern of Staphyloccus Aureus in Surgical site Infections after Elective Surgery

ABSTRACT

To determine the sensitivity pattern of Staphylococcus au reus in surgical site infection after elective surgery. Cross sectional descriptive. January1, 2012 to May 31,2013. Patients with minor or major surgical site infection [SSI] were selected by the treating surgeons and swabs taken for culture and sensitivity testing on blood agar, chocolate agar and MacConkey's agar plates [incubated at 370C] aerobically. The suspected colonies were subjected to catalase test and later coagulase test to confirm as Staphylococcus au reus and tested for sensitivity against commonly used antibiotics. Staphylococcus au reus was isolated in 59.2% of positive cultures. The highest resistance of S.aureus was against Cefixime [95.1%] followed by Cefaclor [77.1%]. The least resistance was against Sulbactam and Cefoperazone [8.2%] followed by Sparfloxacin [11.5%] and Amikacin [16.4%]. S. au reus was variably resistant to other commonly used drugs. Staphylococcus aureus is sensitive to less commonly used drugs like combination of Sulbactan and Cefoperazone and Sparfloxacin. Resistance to commonly used drugs like Cefixime and Cefaclor exists in surgical site infection and needs appropriate measures for prevention and control
