Vibriosis can significantly reduce herd fertility and reproductive performance without distinctive or obvious signs.
Vibriosis is a venereal disease of cattle caused by a bacterial infection with Campylobacter fetus. It is widespread throughout Australian cattle herds and is regarded as a very common cause of infertility and sporadic abortion in northern Australia.
Vibriosis is spread at joining either from an infected bull to an uninfected cow or vice versa. Infected bulls can act as carriers for many years. Bulls are the main source of infection in a herd.
The initial indication of a vibriosis infection is a poor conception rate, especially in heifers. In newly infected herds conception rates can be as low as 40%. It can permanently damage the reproductive tract in a small percentage of heifers or cows resulting in them becoming barren.
Vaccination is the key to preventing vibriosis. Veterinary advice should be sought to maximise the effectiveness of a vaccination program.
