【摘要】Objective To investigate the clinical distribution,changes of drug resistance and agr genotyping of Staphylo-coccus aureus in our hospital.Methods Methicillin resistant Staphylococcus aureus clinically isolated from our hospital in 2016 was performed drug sensitivity test by the method of micro meat soup and the result was judged;Agr genotyping testing was per-formed by multiplex PCR method.Results 183 strains of methicillin resistant Staphylococcus aureus isolated from October 2015 to March 2017 were mainly derived from 24 departments,and the main sources of infection specimens were secretions,deep sputum and non open pus specimens.Drug sensitivity tests
showed
that
the
sensitive
rate
of
vancomycin,linezolid,tegafur,sulfamethox-azole,rifampicin,moxifloxacin,levofloxacin,ciprofloxacin
and
erythromycin for methicillin resistant Staphylococcus aureus were 100%、100%、100%、83.06%、62.29%、57.38%、55.19%、53%、12.57%,respectively;The genotype of agr was mainly type I, followed by type II and type III.Conclusion Methicillin resistant Staphylococcus
aureus in our hospital was evenly distributed in the whole hospital,and the
drug
resistance
rate
of
erythromycin
was
higher.No
vancomycin,linezolid,and cyclosporine resistant strains were found.%目的 了解我院金黄色葡萄球菌的临床分布、耐药性变迁及agr基因分型.方法 我院临床分离的耐甲氧西林金黄色葡萄球菌,采用微量肉汤法进行药敏试验和结果判断;采用多重PCR法进行agr基因分型测定.结果 2015年10月至2017年3月分离的183株耐甲氧西林金黄色葡萄球菌主要来源于24个科室,感染标本来源主要是分泌物、深部痰及非开放性脓液标本,药敏试验提示万古霉素、利奈唑胺、替加环素、复方新诺明、利福平、莫西沙星、左氧氟沙星、环丙沙星、红霉素对耐甲氧西林金黄色葡萄球菌敏感率分别为100%、100%、100%、83.06%、62.29%、57.38%、55.19%、53.0%和12.57%;agr基因分型以Ⅰ型为主,其次为Ⅱ型、Ⅲ型.结论 我院耐甲氧西林金黄色葡萄球菌于全院均匀分布,对红霉素耐药率较高,未发现对万古霉素、利奈唑胺、替加环素耐药株. 【总页数】5页(1-5)
