摘　　要：目的:探讨尿液细菌L型培养在泌尿系感染诊治中的作用价值。方法:对510例患者中段尿标本采用普通培养和细菌L型培养方法进行检测,并对分离出的细菌进行药物敏感试验分析。结果:共检出细菌230株,其中普通型阳性100例,L型阳性60例,普通型与L型混合感染70例。药物敏感性试验结果显示,所有细菌L型对大环内酯类、四环素类抗生素的敏感性较高;普通型细菌对青霉素类、头孢菌素类抗生素的敏感性较高。结论:泌尿系感染与细菌L型有密切的关系,尿液L型细菌培养可提高细菌检测阳性率,为临床诊断和抗生素的合理使用提供重要依据。Objective：To evaluate the clinical effect of L-form bacterium culture in urine samples from patients with urinary infection.Methods：Five hundred and ten urine specimens were examined with the routine and L-form bacterium culture,the isolated strains were tested with drug susceptibility test.Results：Two hundred and thirty out of 510 urine specimens were identified as bacterial growth.Of them,100 wild-type strains and 60 L-form strains alone were isolated,and both the wild-type and the L-form strains from 70 urine samples.The drug susceptibility test were displayed that all of the L-form strains were susceptible to macrolides and tetracycline antibiotics,while the wild-type to penicllium and cephem antibiotics.Conclusions：Most of the urinary infection may be attributed to L-form bacterium.Therefore,the L-form bacterium culture should be done as a routine test and it contributes to the clinical diagnosis and rational use of antibiotics.
