Campylobacter hyointestinalis: A species of CAMPYLOBACTER isolated from the INTESTINES of PIGS with proliferative ENTERITIS. It is also found in CATTLE and in CRICETINAE and can cause enteritis in humans.Campylobacter: A genus of bacteria found in the reproductive organs, intestinal tract, and oral cavity of animals and man. Some species are pathogenic.Campylobacter Infections: Infections with bacteria of the genus CAMPYLOBACTER.Campylobacter jejuni: A species of bacteria that resemble small tightly coiled spirals.
