Abstract: | F18+ enterotoxigenic and verotoxigenic Escherichia coli (E. coli) are widespread and induce post-weaning diarrhoea and oedema disease, respectively. No commercial vaccine exists. Therefore, the F18 herd seroprevalence of 178 randomly selected pig-breeding farms in northern Belgium was evaluated by determining F18-specific IgG antibody titres in pooled sera of sows per breeding farm. This survey reported the first data concerning F18 herd seroprevalence and showed that F18+ E. coli seroprevalence was common in northern Belgium. Significantly more open pig-breeding farms were F18 seropositive (96.4%) compared to closed (88.8%). Furthermore, no clear association was determined between the F18 herd seroprevalence and the number of sows per breeding farm (rsp = 0.19), or with the number of fattening pigs per breeding farm (rsp = 0.17). |
