摘　　要：目的了解L型细菌在慢性肾盂肾炎的感染及耐药状况。方法对71例患者清洁中段尿做普通细菌培养(B型)、L型细菌培养(L型)及耐药分析。结果细菌阳性率为77.5%,其中单独L型阳性率为49.3%、B型与L型混合感染为15.5%,而B型阳性率仅为12.7%。主要是大肠埃希菌,其次是葡萄球菌;青霉素及头孢噻肟均有较高的耐药率(88.9%及73.6%)。结论L型细菌在慢性肾盂肾炎感染中占主导,β-内酰胺类药物有较高的耐药性,临床治疗应据药敏结果合理选择及时调整抗生素。Objective To study on L-forms bacterial infection and drug resistence of chronic pyelonephritis. Methotis The clean mid urine of 71 patients with pyelonephritis were isolated in ordinary culture media and L-form bacteria culture media, and their drug resistance test were carried out. Results The bacterial positive rate was 77.5% （ L-forms 49. 3% ,L-forms ＋ B-forms was 15.5% ,B-forms 12.7% ）. Main pathogens L-forms was Escherichia coli,then was Staphylococcus. Drug sensitive test showed L-form had high resistance to Penicillin and Cefotaxirne. Conclusions The main pathogens of chronic pyelonephritis was bacterial L-form. The L-forms bacterial culture must to be done as a routine test , It was important that to use antibiotics must be in a rationalway.
