Distribution and drug resistance profile of methicillin-resistant Staphylococcus aureus after orthopaedic surgery
Journal Title: Pakistan Journal of Pharmaceutical Sciences - Year 2015, Vol 28, Issue 3
Abstract
This paper is aimed to comprehend clinical distribution and drug-resistance situation of methicillin-resistant Staphylococcus aureus. This study applied automatic microbe instrument Microscan W /A 96 for strain identification and drug susceptibility screening on the isolated strains. It was found that 312 MRSA strains were isolated in three years, which account for 58.1% of Staphylococcus aureus. MRSA were mainly focused in wound secretion, purulent sputum and prostatic fluid and a few of them were isolated from blood specimens; Endemic area distribution was mainly located in intensive care unit, neurosurgery, respiratory department, dermatology, orthopaedic burns and orthopaedics. MRSA strains showed high drug resistance of 82.37%~100% to most of the antibiotics including vancomycin, cotrimoxazole and rifampicin. Strain was 100% resistance towards ampicillin, amoxicillin/acid, cefalotin, cefazolin, tienam, benzylpenicillin, penicillin and tetracycline and 90% strains resisted clindamycin, cefotaxime, clarithromycin and gentamicin.
