本文报告经洁尿细菌L 型培养确诊的大肠杆菌L 型尿路感染4例。细菌L 型培养方法:将洁尿0.1ml 直接种于改良Kagan 细菌L 型培养基上,典型的细菌L 型有“油煎蛋样”、颗粒型、丝状型3种菌落,菌体革兰氏染色阴性,形态呈多形性。4例患儿有明显的尿路感染症状,尿常规检查正常,红霉素与中药近期疗效均佳,长期随访2例痊愈,1例复发,1例遗留少量白细胞尿,提示细菌L 型具一定致病性,药物治疗易控制,但不易根治,一旦机体免疫力下降,即可繁殖致病。
This article reports 4 cases of L-type urinary tract infection of Escherichia coli confirmed by L-type culture of clean urine bacteria. Bacterial L-type culture method: 0.1ml of urinal is directly planted on the modified Kagan bacterium L-type culture medium. The typical bacterium L type is “fried egg-like”, granular and filamentous type. Negative staining, morphology was pleomorphic. 4 cases of children have obvious symptoms of urinary tract infection, urine routine examination was normal, erythromycin and traditional Chinese medicine are good long-term follow-up, 2 cases were cured, 1 case of recurrence, 1 case left a small amount of leucocytosis, suggesting that certain bacterial L Pathogenicity, drug treatment is easy to control, but not easy to cure, once the body’s immune system, you can reproduce the disease.
