The bacteria is an enteric organism of sheep, goats and cattle and is spread by faecal-oral transmission. The ingestion of ''C.fetus'' during last trimester of pregnancy causes a bacteraemia.

The bacteria can reach the uterus and necrotic placentitis causes late abortion, still birth or weak lambs. Aborted lambs may have round necrotic lesions on the surface of their liver.
