整形外科病房分离菌株的种类及常见菌株的耐药性分析

Distribution and resistance of isolates from plastic surgery department

目的了解整形外科病房分离细菌的种类及耐药性。方法采用全自动微生物鉴定及药敏分析仪,检测2007~2009年间整形外科病房分离的菌株及其对常用抗菌药的敏感性。结果 3年共分离菌株26株、11种细菌,切口创面分泌物或脓液23例,占88.5%;其中革兰阴性菌14株,占53.8%,革兰阳性菌12株,占46.2%。以葡萄球菌最多,占42.3%;葡萄球菌中,金黄色葡萄球菌为主,占72.7%,占总菌株的30.8%。金黄色葡萄球菌对大多数常用抗菌药的耐药性在30%以上,对万古霉素和利奈唑胺极其敏感、耐药率为0。结论整形外科病房分离菌株种类较多,以金黄色葡萄球菌最为多见;该类细菌对大多数抗菌药的耐药性较高,但无万古霉素和利奈唑胺耐药株。

Aim To investigate the resistance and distribution in isolates from plastic surgery department.Methods Isolates＇ distribution and resistance were retrospectively studied in plastic surgery department from January 2007 to December 2009.Results Gram-negative strains was 53.8%（14/26）and gram-positive strains was 46.2%（12/26）in all of the isolates,88.5% of which were from secretion or purulent fluid of incision or wound.Staphylococcus aureus were conmmon in those isolates（30.8%）and resistant to most of antimicrobial agents.There were no isolates with resistance to vancomycin and linezolid.Conclusions The distribution of isolates is extensive in plastic surgery department.Staphylococcus aureus are common in those isolates and resistant to most of antimicrobial agents except for vancomycin and linezolid.
