Also known as Vibriosis and Bovine genital campylobacteriosis (BGC)
Formerly known as bovine vibriosis, Bovine genital campylobacteriosis (BGC) is caused by Campylobacter fetus subsp. venerealis and is characterised by infertility and early embryonic death. There is a history of reduced breeding efficiency in herds where natural breeding is practised, and repeated returns to service with prolonged inter-service intervals. Mid to late term abortion occurs sporadically in a small percentage of infected cows.
The disease is venereally transmitted. Bulls show no clinical signs, but many become carriers and subsequently infect females at service. In cows, the bacterium may colonise the vagina, cervix and uterus (in cases of abortion) and may be present in abomasal fluids of aborted foetuses and uterine discharges. The persistent carrier stage in females is uncommon, though the bacterium may colonise the vagina for a few months after infection.
A similar organism Campylobacter fetus subsp. fetus has been known to cause sporadic abortions in cattle, but is not usually involved with infertility.
Diagnosis is supported by history, clinical signs, demonstration of specific antibodies in the vaginal mucus of affected cows, isolation of bacteria from the prepuce of infected bulls or from aborted foetuses.

Additional information |
In a herd situation, demonstration of antibody in vaginal mucus is the preferred method of diagnosis as it can be difficult to recover the organism from the prepuce. Collect at least ten samples from infertile heifers or cows for representative sampling of a herd. It is best to sample when pregnancy testing reveals infertility. Testing for antibodies after calving may be unreliable, due to the extended interval from the time of infection. Cows which have aborted can be sampled for Campylobacter ELISA from one week to three months after abortion. |

Note: *Media is supplied free of charge to customers (within Australia) who send samples for Campylobacter fetus subsp. venerealis testing at EMAI (NSW DPI). Costs may be recovered for any media supplied but not returned, receipt of compromised/unsuitable samples at the laboratory or cancellation of testing. We require 1 week notice for all media requests or 2 weeks if the number of samples is greater than 20.
Foetal stomach contents |
---|
C. fetus subsp. venerealis is most successfully isolated from aborted foetuses submitted to the laboratory, because the organism is not exposed to normal atmospheric conditions, and where samples can be collected without contamination and then directly cultured under microaerophilic conditions.

For NSW submissions, please contact the relevant Customer Service team for courier account details and to order consignment notes.
For submitters outside of NSW, Couriers can be contacted directly to make bookings and arrange collection of packages at the submitters own cost.
Commercial couriers may use either road or air transport and specimens should therefore be packed in accordance with International Air Transport Association (IATA) requirements. Most submission sent by veterinarians to the SVDL for testing are defined as “Biological Substance Category B” and must be packed according to the IATA packing instructions 650 (Biological Substance Category B). As requirements for transport can change, customers should consult with their transport agent to obtain current requirements.
Samples may also be hand delivered to the site during normal business hours (8.30am - 4.30pm).
