Nine strains of Campylobacter fetus subsp. jejuni were isolated from the stools of diarrhoeic children in Colombo (Sri Lanka). The morphology of most of the strains was typical but three strains produced a spreading film of growth. No discrete domed colonies were seen. All were able to grow in a candle jar, and in a medium containing 1% glycine. All produced hydrogen sulphide. All were susceptible to ampicillin, carbenicillin, tetracycline, chloramphenicol, neomycin, erythromycin, gentamicin and furoxone .
