Campylobacteriosis (vibriosis) is a venereal disease of cattle caused by the organism Campylobacter fetus subspecies fetus previously known as Vibrio fetus subspecies venerealis. Characteristically the disease causes infertility in the female with an increased number of services necessary for conception. Abortions late in gestation are also occasionally seen. Most cases or outbreaks occur after the recent introduction of an infected bull or cow into a susceptible breeding herd. Often the disease remains undetected until late fall when the livestock owner recognizes that he has a number of females exhibiting estrus. A tentative diagnosis can be made by a study of the herd history and can often be confirmed by laboratory means.In recent years many advances have been made towards establishing an understanding of the immune response that occurs with infection and systemic immunization. In this review, recommendations are made regarding the appropriate time to immunize the breeding herd against campylobacteriosis.
