摘要
目的动态观察并分析解放军第174医院2006年10月—2009年9月3年间产超广谱β-内酰胺酶(ESBLs)肺炎克雷伯菌的检出率及耐药性变化,为临床准确合理地进行治疗提供依据。方法采用美国临床实验室标准化委员会或研究所(NCCLS/CLSI)推荐的纸片扩散确证法检测ESBLs,纸片扩散法做药敏试验,WHONET5.3分析软件对药敏试验进行统计,并对产和非产ESBLs菌株的药敏试验数据进行对比分析。结果369株肺炎克雷伯菌中ESBLs阳性共211株,占57.2%,且3年来阳性率逐年显著性增高。产ESBLs肺炎克雷伯菌的耐药率明显高于非产ESBLs菌株,且具有多重耐药性。结论该院肺炎克雷伯菌产ESBLs率逐年升高,治疗时应考虑首选亚胺培南。
[Objective]To dynamically observe the detection rate and variation of drug resistance of ESBLs-producing Klebsiella in PLA No.174 Hospital from October 2006 to September 2009,and provide evidence for reasonable use of antibiotics in clinic.[Methods]ESBLs were detected by the method recommended by National Committee for Clinical and Laboratory Standards Institute （NCCLS/CLSI）.The antibiotic susceptibility was tested by the Kirby-Bauer method and the data were analyzed by the software of WHONETS.3.The antibiotics susceptibility test data of either ESBLs-producing or non-producing strains was analyzed comparatively.[Results]Of 369 strains of Klebsiella pneumoniae,211 strains were ESBLs positive,occupying 57.2%.And the positive rate increased annually in recent 3 years.The antibiotic resistance rate of ESBLs-producing strains was higher than that in non-producing strains,with multi-antibiotic resistance.[Conclusion]The positive rate of ESBLs producing Klebsiella pneurnoniae increases annually in this hospital,so that imipenem is preferred for clinical treatment.
