objective to study the risk factors on esbl producing strains of k.pneumoniae and e.coli.methods aprospective survey on esbl producing strainsof k.pneumoniae and e.coli for a36-month period.results the resistance rates ofe.coli were:98.08%for ctx,73.08%for amc.the resistance rates of k.pneuˉmonialwere;95.74%for ctx,97.87%for amc.the use rate of third generation cephalosporins was much higher than those of esbls nonproducing strains（p.05）.it induce esbls that3rd generation cephalosporins were used extensive.after strenghtening the antibiotic controls,esbls detection rate has gone down.conclusion the factors of infection of esbl-producing strains were the severity diseases,cellular immunological condition,improper medical manipulations.to prevent esbl-producing strains,reasonable antibiotics usage may be the effective measure.

目的 分析临床大肠埃希菌及肺炎克雷伯菌产esbls的危险因素，并加以控制。方法前瞻性监测产esbls菌的情况，并对感染者进行临床调查。结果产esbls的大肠埃希菌、肺炎克雷伯菌的耐药率头孢噻肟钠为98.08%和95.74%，阿莫西林+棒酸为73.08%和97.87%，产esbls菌感染者头孢第三代的使用率（70.21%）显著高于非产esbls菌感染者（39.47%）（p.05）；第三代头孢的大量使用诱导esbls的产生。通过加强抗感染药物的使用管理esbls检出率开始下降。结论严重的基础病、高龄、机体免疫力低下，长期住院者是esbls菌感染的易感宿主，皮质激素、化疗及介入性疗法是esbls感染的高危因素。滥用抗感染药是产生esbls的重要因素，合理使用抗感染药是防止esbls产生的主要措施。
