Ovine Brucellosis in South Australia

Ovine brucellosis (OB) is an infectious bacterial disease causing infertility in sheep. The disease can lead to reduced ram fertility, and occasionally, abortions in ewes or the birth of weak lambs. OB is a venereally transmitted disease.

It is of economic importance to many sheep producers as brucellosis-infected rams often mean a lower lambing percentage and prolonged lambing period.  The cost of the disease to individual producers through lost production can be high. In SA OB is NOT a notifiable disease.

Stud flocks registered with their breed association can undertake testing and become an accredited Ovine Brucellosis Free property. If you would like more information on the accreditation program, this can be obtained from your breed association or PIRSA Biosecurity - Animal Health.

A recent survey of sheep flocks by PIRSA Biosecurity – Animal Health on the Eyre Peninsula, found that around 5% of properties were infected with OB. None of the properties that tested positive were aware the disease was present in their rams. This followed on from a similar survey in the pastoral region where nearly 10% of properties were shown to be infected with OB.  A similar survey in the Mallee region found 13% of flocks to be positive. In 2010 a survey of sheep flocks in the South East of the state will be undertaken to further our understanding of the prevalence of this disease in South Australia.
