Campylobacter live on the mucosa of the intestinal and genital tract and can be commensals or pathogens. The enteric species cause disease in humans and other species cause infertility and abortion in cattle and sheep. [[Campylobacteriosis]] is caused by Campylobacter organisms.

''C. fetus'' subspecies [[Campylobacter fetus subspecies fetus|''fetus'']] and subspecies [[Campylobacter fetus subspecies venerealis|''venerealis'']] possess a microcapsule (S layer) which resists phagocytosis and serum-mediated destruction and enhances survival in the genital tract.

Antigens of the S layer undergo antigenic shifts in ''C. fetus'' subspecies [[Campylobacter fetus subspecies venerealis|''venerealis'']], allowing persistence in the host.
