Abstract
A survey was conducted to establish the prevalence of Campylobacter in pigs from an integrated commercial hog farm. This study was carried out in four different groups of pigs: 1) adult gilts (50); 2) pregnant sows (9); 3) piglets at day-of-birth (73); 4) weaned piglets (20). Rectal and/or caecal samples were collected from each pig.Campylobacter was cultured and enumerated from such samples using Bolton enrichment broth and Campy-Cephex agar plates. Both biochemical and serological tests were used to determine Campylobacter species. Gilts had a 76 per cent incidence ofCampylobacter with a mean of 76·3 per cent for C. jejuni, 21 per cent for C. coli and 2·6 per cent for C. lari. Pregnant sows had a 100 per cent incidence of Campylobacter with a mean of 87 per cent forC. jejuni and 13 per cent for C. coli. Newborn piglets had a 57·8 per cent incidence ofCampylobacter , rising to 100 per cent by the time of weaning. Thus it appears that pigs, from the day of birth, are highly susceptible to colonisation by Campylobacter.
