湖北地区外科感染常见致病菌1314株耐药性监测分析

目的 了解湖北地区外科致病菌的菌群分布及其耐药状况。方法 将湖北地区15所医院所做20种抗菌药物对外科分离菌的的抑菌圈直径输入计算机，采用WHONET－4软件进行统计和分析；根据1999年美国临床实验室标准委员会发布的标准判断细菌耐药。结果 1998年10月至1999年9月收集外科感染菌株1314株。金黄色葡萄球菌、绿脓假单胞菌、大肠埃希菌、肠杆菌属和凝固酶阴性葡萄球菌最常见。44．6％的葡萄球菌对苯唑西林耐药（MRS）；对万古霉素耐药的肠球菌（VRE）为4．3％。亚胺培南、阿米卡星、头孢他啶、环丙沙星对革兰阴性杆菌的敏感率为84．4％－57．2％。结论 在外科领域开展细菌耐药性监测工作，随时掌握细菌耐药状态，对合理用药具有很大的实用价值。

A surveillance on the bacterial resistance in surgical infection in Hubei area

Objective　To study the antimicrobial resistance of isolated pathogens from surgical infections in Hubei area.Methods　The diameters of the inhibition zones of surgical isolates around antibiotic susceptibility test discs in 15 hospitals were computerfiled and analysed by the software of “WHONET-4” according to NCCLS published in 1999.Results　A total of 1314 surgical isolates were collected between October 1998 and September 1999.S.aureus,P.aeruginosa,E.coli,Enterobacter sp.and CNS were the main microorganisms.44.6% of staphylococcus was resistant to oxacillin.Imipenem,amikacin,ceftazidime and ciprofloxacin were most active against Gram-negative bacilli with the sensitities (in descending order) of 84.4% to 57.2%.Conclusion　Antimicrobial resistance should be seriously considered during surgical therapy and prohylaxis with antimicrobial agents.The tendency to antimicrobial resistance of clinical isolates should be followed up continuously.
