Animal disease categories: D E

Profile

Bovine genital campylobacteriosis is a disease of cattle that can cause fertility problems or abortions.

Occurrence

worldwide

Host animals

Cattle

Mode of transmission

Bulls become infected during mating and in insemination stations through contaminated equipment. Cows are infected during mating or through contaminated semen.

Incubation period

Abortions are possible at all stages of pregnancy.

Symptoms

In cows, most common are umbilications and prolonged intercalving periods; abortions are rare. Bulls usually show no clinical symptoms.

Therapy

Antibiotic treatment does not guarantee freedom from the pathogen. In valuable bulls, the pathogen can also be controlled with inactivated vaccines.

Prevention

Insemination bulls are monitored bacteriologically to prevent the pathogen from being reintroduced into domestic herds.

Situation in Austria

Bovine genital campylobacteriosis has been practically eradicated in Austria. The disease is notifiable according to the Breeding Diseases Act.

Professional information

The parasite occurs worldwide in cattle. The reservoir is the preputial mucosa of clinically healthy bulls. Campylobacter fetus subsp. venerealis can cause fertility problems in cattle with failure to conceive or implant, early embryonic death or abortion.Antibiotic treatment does not guarantee freedom from the pathogen. In valuable bulls, the pathogen can also be controlled with inactivated vaccines. In contaminated semen, neither deep freezing nor antibiotic addition will reliably kill the parasite.

Diagnostic

The preputial fluid of insemination bulls is examined culturally-bacteriologically. Due to the sensitivity of the pathogens, the samples shall be transported to the laboratory within 6 hours in a special transport medium. In addition, the samples are also examined microscopically and culturally for trichomonads.

Differentially, Campylobacter fetus subsp. fetus and other Campylobacter species are to be excluded.

Pathogen identification is performed microscopically, based on growth behavior and antibiotic sensitivity, as well as by biochemical methods and PCR.
