Antimicrobial-resistant Profile of Staphylococcus aureus from Different Origins / 中华医院感染学杂志

ABSTRACT

OBJECTIVE To investigate the antimicrobial-resistance of Staphylococcus aureus isolates which obtained from different origins.METHODS The isolates of S.aureus were derived from clinical samples by routine methods.The identification and susceptibility test of the isolates were determined by Automated Microbiology Analyzer.Disk-diffusion test(K-B method) was used for detecting meticillin-resistant S.aureus(MRSA).?2 Test was made to identify the significance of difference.RESULTS A total of 248 S.aureus strains were isolated from blood(25),medical internal catheter(27),pus(89),sputum(93),and urine(14).All isolates of S.aureus were sensitive to nitrofurantoin and vancomycin.The resistant rates of S.aureus isolates from pus to chloramphenicol,gentamicin,oxacillin,penicillin,rifampicin,tetracycline and levofloxacin all significantly lower than those of isolates from sputum(P
