Strains of Escherichia coli isolated from random fecal samples, urines of hospitalized and nonhospitalized patients who had urinary tract infections, and blood of patients with septicemia were examined for colicin V production. The percentage of ColV+ strains isolated from blood (31.6%) or from urines of hospitalized patients with urinary tract infections (26.2%) was significantly greater (P less than 0.01) than the percentage isolated from feces (13.6%). The colicin V immunity determinant of ColV,I-K94 conferred immunity to 26% of the type V colicins produced by clinical isolates. Of the ColV+ strains studied, 63.6% produced at least one other type of colicin.
对从随机粪便样本、患有尿路感染的住院和非住院患者尿液以及败血症患者血液中分离出的大肠杆菌菌株进行了产大肠杆菌素V的检测。从血液(31.6%)或患有尿路感染的住院患者尿液(26.2%)中分离出的ColV+菌株的百分比显著高于从粪便中分离出的百分比(13.6%)(P小于0.01)。ColV,I-K94的大肠杆菌素V免疫决定簇赋予了对临床分离株产生的26%的V型大肠杆菌素的免疫力。在所研究的ColV+菌株中,63.6%至少产生了一种其他类型的大肠杆菌素。
