**3.2** *Campylobacter enteritis* **(Vibrionic enteritis, vibriosis)**

Intestinal campylobacteriosis occurs by *Campylobacter jejuni* or *Campylobacter coli*. Although they compete in the digestive system of many species, they can cause diarrhea, especially in small animals. *Campylobacter fetus* can also cause reproductive diseases and abortion in cattle. *Campylobacter* spp., especially *C. jejuni* and *C. coli*, are a major cause of enteritis in humans. Additional species cause venereal diseases in sheep and cattle. Many animals carry *Campylobacter* spp. without any symptoms, throwing the organism in their feces or stools. Bulls can be vaccinated annually against the campylobacteriosis [5].

Vaccinations are also available for cows and make the animal very resistant to infection. It can help biosecurity and the examination of bulls purchased in the identification of the disease. If the ox has to be bought, the best policy is the younger the better. If you are forced to buy a mature bull, use antibiotics before using it to breed cows and use them on a small number of cows only so that their fertility can be recorded before they are used for service in the original herd.
