Bovine genital campylobacteriosis
Campylobacter fetus subsp. venerealis
Technical information
The pathogen is found in cattle worldwide. The reservoir is the prepucial mucosa of clinically healthy bulls. Campylobacter fetus subsp. venerealis can cause fertility problems in cattle, including failure to conceive or implant, early embryonic death or abortion.
Antibiotic treatment does not guarantee the complete eradication of the pathogen. In the case of contaminated semen, Campylobacter fetus subsp. venerealis is not reliably killed by either deep-freezing or the addition of antibiotics.
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.
