Midstream samples of urine from 185 acutely dysuric women and 89 symptom-free controls were screened according to the modified criteria of Kass by both conventional and microaerophilic culture. Among the 185 symptomatic women, coliform bacilli were isolated from 125 (67.5%) and in 45 (36%) of the latter the concentration of these organisms in the urine was less than 10(8)/l. Fastidious organisms were isolated in pure and mixed cultures from 25 (13.4%) of the 185 patients and from 4 (4.5%) of 89 controls. Staphylococcus species were isolated from 10.8% (9.7% S. saprophyticus; 1.1% S. epidermidis) and Ureaplasma urealyticum from 2.7%. All patients infected with conventional organisms but only 30.4% of those yielding fastidious organisms had pyuria. The isolation rate of fastidious organisms tended to be higher (P = 0.055) in symptomatic women that in symptom-free controls.
按照改良的卡斯标准，采用常规培养和微需氧培养法对185名急性排尿困难女性及89名无症状对照者的中段尿样本进行筛查。在185名有症状的女性中，125例（67.5%）分离出大肠埃希菌，其中45例（36%）尿液中该菌浓度低于10⁸/L。从185例患者中的25例（13.4%）以及89名对照者中的4例（4.5%）中分离出苛养菌，为纯培养或混合培养。葡萄球菌属分离率为10.8%（腐生葡萄球菌9.7%；表皮葡萄球菌1.1%），解脲脲原体分离率为2.7%。所有感染常规菌的患者中存在脓尿，但在分离出苛养菌的患者中只有30.4%存在脓尿。有症状女性中苛养菌的分离率往往高于无症状对照者（P = 0.055）。
