Overview
Campylobacter fetus is a species of Gram-negative, motile bacteria with a characteristic "S-shaped" rod morphology similar to members of the genus Vibrio Template:Ref N. Like other members of the Campylobacter genus, C. fetus is oxidase-positive.
Pathogenesis
In addition to causing some cases of abortion in cattle and sheep, C. fetus is an opportunistic human pathogen and can cause bacteremia and thrombophlebitisTemplate:Ref N. Though rare, C. fetus can lead to fatal septicemia in newborns and immunocompromised individualsTemplate:Ref N. Bacteremia can lead to localized infections of the meninges in the brain, the respiratory pleural spaces or lungs, jointsTemplate:Ref N, the pericardial sac around the heart, or the peritoneum.
