Hybridizations were done on bovine enterotoxigenic Escherichia coli with 2 heat-stable (ST) enterotoxin gene probes from porcine and human origin (STp and STh). Of the baby mouse-positive isolates, 56 (53%) hybridized the STp probe and 50 (47%) did not. There was no isolate that hybridized the STh probe. Hybridization with the Stp probe was more frequent (P less than 0.005) for E coli isolated from calves that died before 2 weeks of age (49 STp-positive isolates of 77 [64%] isolates) than for E coli isolated from calves that died after 2 weeks of age (2 STp-positive of 21 [10%] isolates).
使用来自猪和人的2种热稳定（ST）肠毒素基因探针（STp和STh）对牛产肠毒素大肠杆菌进行杂交试验。在对乳鼠呈阳性的分离株中，56株（53%）与STp探针杂交，50株（47%）未杂交。没有分离株与STh探针杂交。与STp探针杂交在2周龄前死亡的犊牛分离的大肠杆菌中更为频繁（P小于0.005）（77株分离株中有49株[64%]STp阳性分离株），而在2周龄后死亡的犊牛分离的大肠杆菌中则较少（21株分离株中有2株[10%]STp阳性）。
