Baby pigs orally inoculated with a porcine strain of enterotoxigenic Escherichia coli (K88+,Ent+) showed signs of depression, severe diarrhea, and, in some instances, death. Few, if any, signs of illness occurred if baby pigs were first inoculated with a K88 possessing non-enterotoxin-producing strain of E. coli.
口服接种产肠毒素大肠杆菌猪菌株(K88 +,Ent +)的仔猪出现抑郁、严重腹泻症状,在某些情况下还会死亡。如果仔猪先接种具有不产肠毒素的K88大肠杆菌菌株,则几乎不会出现疾病迹象。
