Phenotyping of <Emphasis Type="Italic">E. coli</Emphasis> serotypes associated to oedema disease

Background  

Oedema disease is a severe disease, mainly affecting recently weaned pigs. It is caused by E. coli strains that express fimbriae F18 and produce verotoxin 2e, mainly belonging to serotype O138, O139 or O141. The aim of this study was to compare E. coli isolates within these serotypes with respect to diversity.
