我院１９９１～１９９２年度对５８５例患者１２５４份尿标本进行病原学分离培养鉴定，菌株培养阳性率为３１．７％，两年度均以革兰阴性菌为主，霉菌有上升。送检患者分为免疫功能低下及正常两组，分析比较病原菌特点。前组菌种类别多但分布分散，常有少见菌；后组菌种集中，主要种类依次为；大肠埃希氏菌、白色念珠菌、粪肠球菌、金黄色葡萄球菌。文中对重复及多重感染、老年无症状菌尿及部分菌种药敏趋势也进行了分析。
In our hospital from 1991 to 1992, 584 patients with 1254 urinary specimens were isolated and identified by etiology. The positive rate of strain culture was 31.7%. Gram-negative bacteria were dominant in both years, and molds increased. The patients were divided into two groups of immunocompromised and normal, analysis of the characteristics of pathogens. The species of the former group were mostly distributed but dispersed, and often had rare bacteria. The latter species were concentrated, followed by Escherichia coli, Candida albicans, Enterococcus faecalis and Staphylococcus aureus. In this paper, repeated and multiple infections, the elderly asymptomatic bacteriuria and some strains of drug susceptibility trends were also analyzed.
