452例革兰阳性葡萄球菌耐药分析

目的了解葡萄球菌最新分离情况及耐药分析。方法采用K-B法检测我院临床分离的革兰阳性葡萄球菌对抗生素的敏感性。按照美国国家临床实验室标准委员会（CLSI/NCCLS）2005的标准进行分析。结果检测有菌阳性标本1419例。革兰阳性葡萄球菌检出452例,检出率为31.9%。其中,凝固酶阳性金黄色葡萄球菌（MSSA）4.3%,耐甲氧西林凝固酶阳性金黄色葡萄球菌（MRSA）检出率为17.5%,凝固酶阴性金黄色葡萄球菌（MSSCoN）9.5%,耐甲氧西林凝固酶阴性金黄色葡萄球菌（MRSCoN）检出率为39.9%。粪肠球菌检出204例,检出率为14.4%。屎肠球菌检出204例,检出率为14.4%。耐甲氧西林凝固酶阴性金黄色葡萄球菌（MRSCoN）感染明显上升,同时也是检出率最高的。粪肠球菌和屎肠球菌检出率相当,但屎肠球菌耐药性明显高于粪肠球菌。结论葡萄球菌感染在临床非常普遍,MRSA和MRSCoN也出现了严重的耐药性。

Antimicrobial-resistant Profile of gram positive Staphylococci

Objective To investigate the isolated situation of Staphylococci and the antimicrobial-resistant profile.Methods Antimicrobial susceptibility test of the isolated Staphylococci from our clinical department were conducted by Kirby-Bauer method,and the results of tests were judged according to CLSI /NCCLS 2005 standard.Results Of the 1419 clinical isolates with bacteria,452 strains were gram positive Staphylococci,accounted for 31.9%.Among the Staphylococci,MSSA accounted for 4.3%;MRSA accounted for 17.5%;MSS...
