目的进一步探讨对老年丝虫性乳糜尿患者细菌Ｌ型感染情况。方法采用改良的Ｋａｇａｎ氏培养基及常规血培养基，分离乳糜尿患者尿中细菌型、细菌Ｌ型并做药物敏感试验。结果从１０５例老年丝虫性乳糜尿患者的清洁中断尿中分离出细菌Ｌ型４８株，其菌落特征、革兰氏染色、细胞壁染色等均符合细菌Ｌ型的特点，经返祖鉴定为金黄色葡萄球菌３０株、表皮葡萄球菌１０株、大肠杆菌７株、未鉴定１株。结论提示丝虫性乳糜尿患者常伴有细菌Ｌ型的尿路感染，细菌Ｌ型感染与患者尿液蛋白排出量、病程有密切的关系，可加重乳糜病情，致病程迁延不愈。
Objective To further investigate the bacterial L-type infection in elderly filagial chyluria patients. Methods The modified Kagan’s medium and routine blood culture medium were used to separate the urinary bacterial and L-forms in patients with chyluria and do the drug sensitivity test. Results The bacterial L-type isolates were isolated from 105 cases of chronic filarial chyluria patients. The colony characteristics, Gram staining and cell wall staining were all consistent with the characteristics of bacterial L-form. Staphylococcus aureus 30, Staphylococcus epidermidis 10, Escherichia coli 7, not identified a. Conclusions The patients with filarial chyluria are often accompanied by bacterial L-type urinary tract infection. The bacterial L-type infection is closely related to the patient’s urinary protein excretion and duration of disease, which may aggravate the disease of chylous and prolong the course of disease.
