Hemorrhagic gastroenteritis caused by Escherichia coli in piglets: Clinical, pathological and microbiological findings

[摘要] A retrospective study (1980-1989) was conducted to describe the clinical, pathological, and bacteriological findings in 55 cases of hemorrhagic gastroenteritis (HGE) caused by Escherichia coli in piglets. The condition occurred in weaned and suckling piglets and was associated with several serogroups of E. coli. Most of the isolates of E. coli possessed the adhesin F4 (K88) and were hemolytic. Only a few of the isolates of E. coli tested produced verotoxins. Clinical signs and pathological findings noted in these cases were compatible with shock.
