摘要
目的研究医院就诊患者感染葡萄球菌临床分布及耐药性分析。方法采用分离鉴定技术和K-B纸片扩散法,检测某医院就诊患者感染标本并对分离菌株进行药敏试验。结果 6个月内,从该医院就诊患者感染标本中共分离出葡萄球菌97株,其中耐甲氧西林金黄色葡萄球菌(MRSA)32株,耐甲氧西林凝固酶阴性葡萄球菌(MRCNS)39株。在检出的97株葡萄球菌中,有42.3%分离自痰标本,32.0%分离自血液,23.7%分离自分泌物。临床分离的葡萄球菌对青霉素和红霉素的耐药率分别为90%以上和45%以上。结论葡萄球菌主要引起呼吸道感染,检出率最高的是痰标本,耐药现象普遍,应加强合理使用抗菌药物的教育和管理。
Objective To investigate the characteristic of clinical infection and drug resistance of methicillin resistant Staphylococcus aureus.Methods The isolation and identification methods and the K-B method were used to perform detection of infectious specimen of patients in some hospital.Results The strains were isolated from different kinds of specimens from October 2011 to April 2012.In 97 isolated strains of Staphylococci,32 samples were methicillin-resistant Staphylococcus aureus（MRSA）,39 samples were methicillin resistant coagulase-negative Staphylococci（MRCNS）.The detection rate of the 97 isolated strains were predominant in sputum（42.3%）,blood（32%）,secretion（23.7%）.The resistant rate to Penicillin,Erythromycin were 90% and 45% respectively.Conclusion The Staphylococci is responsible for infection of the respiratory tract.The positive rate is the highest in the phlegm sample and extensive drug resistance is common.It is important to introduce the essential principles and rational management of antimicrobial agents.
