The occurrence of Escherichia coli possessing P blood-group-specific adhesins (P-fimbriae) was examined in 97 children with urinary tract infections and 82 healthy controls. P-fimbriae were present in 91% (33/35) of the urinary strains causing acute pyelonephritis. Among strains causing cystitis and asymptomatic bacteriuria P-fimbriae were found in 19% and 14% of cases, respectively. Only 7% of faecal isolates from healthy controls carried P-fimbriae. The results were similar in three different studies. In most of the children with acute pyelonephritis the urinary pathogen was the predominant E. coli strain of the periurethral and faecal flora.
对97名患有尿路感染的儿童和82名健康对照者进行了研究，检测携带P血型特异性黏附素（P菌毛）的大肠杆菌的出现情况。在导致急性肾盂肾炎的泌尿菌株中，91%（33/35）存在P菌毛。在导致膀胱炎和无症状菌尿的菌株中，分别有19%和14%发现有P菌毛。健康对照者的粪便分离株中只有7%携带P菌毛。三项不同研究的结果相似。在大多数患有急性肾盂肾炎的儿童中，尿路病原体是尿道周围和粪便菌群中占主导地位的大肠杆菌菌株。
