Serogroups of 1334 E. coli colonies isolated in Spain between 1986 and 1991 from piglets with diarrhoea, oedema disease and from healthy piglets, were determined. The serogroups determined in E. coli from diarrhoea were: O1, O2, O4, O5, O7, O8, O9, O12, O20, O21, O23, O25, O26, O32, O39, O45, O54, O75, O78, O80, O83, O91, O92, O101, O103, O113, O115, O116, O118, O125, O127, O138, O139, O141, O149, O153 and O157; from pigs with oedema disease: O8, O101, O138, O149 and O157; and from healthy piglets: O1, O2, O5, O7, O8, O9, O20, O21, O26, O29, O45, O64, O71, O80, O81, O91, O101, O105, O113, O115, O116, O126, O128, O132, O138, O139, O142, O146, O149, O152, O153, and O168. Serogroups O138, O141 and O149 were found to be statistically associated with enteric porcine colibacillosis (diarrhoea and oedema disease) (0.025 > P < 0.01). In addition, enterotoxigenic (ETEC) strains belonged to serogroups: O8, O9, O20, O101, O138, O141 and O149; verotoxigenic (VTEC) strains (VTEC) strains to serogroups 091 and 0138; and necrotizing (NTEC) strains to serogroups O2, O4, O8, O54, O78 and O83. Furthermore, 91.2% (249 out 273) of the ETEC (LT and/or STa) and/or VTEC strains belonged to only seven different serogroups. These major serogroups to which the ETEC and VTEC strains belonged, were determined in a lower percentage (21.2%) among non-toxigenic E. coli colonies isolated from sick and healthy piglets.
测定了1986年至1991年间在西班牙从患有腹泻、水肿病的仔猪以及健康仔猪中分离出的1334株大肠杆菌菌落的血清型。从腹泻仔猪中分离出的大肠杆菌血清型有：O1、O2、O4、O5、O7、O8、O9、O12、O20、O21、O23、O25、O26、O32、O39、O45、O54、O75、O78、O80、O83、O91、O92、O101、O103、O113、O115、O116、O118、O125、O127、O138、O139、O141、O149、O153和O157；从患有水肿病的仔猪中分离出的有：O8、O101、O138、O149和O157；从健康仔猪中分离出的有：O1、O2、O5、O7、O8、O9、O20、O21、O26、O29、O45、O64、O71、O80、O81、O91、O101、O105、O113、O115、O116、O126、O128、O132、O138、O139、O142、O146、O149、O152、O153和O168。发现血清型O138、O141和O149与猪肠道大肠杆菌病（腹泻和水肿病）存在统计学关联（0.025＞P＜0.01）。此外，产肠毒素大肠杆菌（ETEC）菌株属于血清型：O8、O9、O20、O101、O138、O141和O149；产志贺毒素大肠杆菌（VTEC）菌株属于血清型O91和O138；坏死性大肠杆菌（NTEC）菌株属于血清型O2、O4、O8、O54、O78和O83。此外，91.2%（273株中的249株）的ETEC（LT和/或STa）和/或VTEC菌株仅属于7种不同的血清型。从患病和健康仔猪中分离出的非产毒大肠杆菌菌落中，ETEC和VTEC菌株所属的这些主要血清型的比例较低（21.2%）。
