A clinical study was made on the relationship between the blood type P1 antigen and urinary tract infection (UTI). The blood type P1 antigen could be detected in 3 out of 11 healthy Japanese volunteers (27.2%), and in 54% of the UTI patients as a whole. Classified by the type of infection, it could be detected in 3 out of 4 patients with upper UTI (75%) and in 11 out of 22 patients with lower UTI (50%). These incidences were higher than that of healthy volunteers, the difference being statistically significant. The relationship between the annual frequency of UTI and the positive detection of P1 antigen was examined. The patients who had been exposed to UTI twice or more a year proved to have a higher detection rate (61%), than the other group of patients, the difference being statistically significant. Two of the patients with E. coli detected as a clinical isolate proved to have the P1 antigen.
对血型P1抗原与尿路感染（UTI）之间的关系进行了一项临床研究。在11名健康的日本志愿者中，有3人（27.2%）可检测到血型P1抗原，而在所有UTI患者中这一比例为54%。按感染类型分类，4例上尿路感染患者中有3例（75%）可检测到该抗原，22例下尿路感染患者中有11例（50%）可检测到。这些发生率高于健康志愿者，差异具有统计学意义。研究了UTI年发病频率与P1抗原阳性检测之间的关系。每年发生UTI两次或以上的患者检测率（61%）高于其他患者组，差异具有统计学意义。作为临床分离株检测出的2例大肠杆菌患者被证实具有P1抗原。
