A TOTAL of 75 faecal samples were collected from 30 ……. apparently normal and 45 diarrheic sheep. The bacteriological examination revealed isolation of C. jejuni and C. coli from 9 (12%) and 3 (4%) of examined sheep respectively. The prevalence of C. jejuni and C. coli were higher in the diarrheic sheep (15.6%) and (4.4%) than the apparently healthy (6.66%) and (3.33%) respectively. Campylobacter isolates were identified biochemically and serologically and using pathogenicity test two antigens cytotoxin and whole cell antigens associated with campylobacter. Campylobacter whole cell and cytotoxins were identified for their immunogenic activity by neutralization test and ELISA. Campylobacter isolates were also tested for susceptibility against 9 antibiotics.
