Abstract

Five intestinal strains of Campylobacter isolated from pigs and cattle are discribed. The strains grew in anaerobic as well as in micro-aerobic environment; they were catalase positive and resistant to nalidixic acid but sensitive to cephalothin and metronidazole. They had a mean G+C content of 35.4 mol%. DNA-DNA-hybridizations showed that the group was homogeneous: about 50% related to C. fetus ss fetus and less than 25% related to other Campylobacter species.
