The distribution of K1, K5 and O antigens was examined in 500 clinical strains of Escherichia coli. Of 400 strains from urine, 52% belonged to serogroups O1, O2, O4, O6, O7, O8, O9, O18, O25 and O75; 34% were non-typable (NT) and 14% were autoagglutinable (AA). Antigen K1 was carried by 17% of these strains, and K5 by 15%. The numbers of O-serogroupable, NT and AA strains among 100 strains from blood were 62, 29 and 9, respectively. K1 antigen was detected on 20% of isolates from blood and K5 on 13%. There was no statistically significant difference in the distribution of K1, K5 or O antigens between strains from blood compared with those from urine. The occurrence of K1 and K5 antigens among smooth and AA strains suggested that AA strains were derived primarily from the common O-serogroups.
对500株临床大肠杆菌菌株进行了K1、K5和O抗原的分布检测。在400株尿液来源的菌株中，52%属于O1、O2、O4、O6、O7、O8、O9、O18、O25和O75血清群；34%为不可分型（NT），14%为自凝性（AA）。这些菌株中17%携带K1抗原，15%携带K5抗原。在100株血液来源的菌株中，可进行O血清群分型、NT和AA菌株的数量分别为62、29和9。血液来源的分离株中20%检测到K1抗原，13%检测到K5抗原。与尿液来源的菌株相比，血液来源的菌株中K1、K5或O抗原的分布没有统计学上的显著差异。光滑型和AA菌株中K1和K5抗原的出现表明，AA菌株主要来源于常见的O血清群。
