Campylobacter Vaccine Sheep

There exists a multitude of possible causes for abortion and infertility in the breeding ewe. Infectious and non-infectious agents can both play a role in abortion investigations. In Australia, abortion is an uncommon cause for reproductive wastage, as compared to other countries where intensive systems of lambing management are used. Ovine campylobacteriosis (also known previously as vibriosis and epidemic abortion) is caused by Campylobacter fetus fetus and Campylobacter jejuni. Both organisms are capable of causing abortion in ewes; however C.fetus fetus remains the major cause of campylobacter associated abortions in Australia and New Zealand2. Ovine campylobacteriosis has been reported in all states and territories in Australia.

Making a definitive diagnosis can often prove difficult as animal health staff are often told about the abortions/infertility issues at a time when testing is not worthwhile (eg. owners noticed abortions/perinatal deaths but only began investigation around marking or weaning time). Appropriate sampling is essential in including or excluding various infectious or non-infectious causes of abortion. 


Campylobacter vaccine for sheep (breeding ewes). Prevents abortion and perinatal loss caused by Campylobacter fetus fetus, and induces a specific immune response C.jejuni. Campylobacter spp. are Gram-negative, non-sporing, curved or spiral rod-shaped bacteria that colonize the gastrointestinal tract of a broad range of animals, and can cause associated disease in cattle, pigs and poultry. Campylobacteriosis in sheep is caused by either Campylobacter fetus ssp. fetus intestinalis (C. fetus subsp fetus) or Campylobacter jejuni (C. jejuni).

In recent years there has been a shift from C. fetus subsp fetus being the predominant isolate in the US, to C. jejuni . In the US, treatment or prevention of abortion storms associated with Campylobacter spp. traditionally relied on chlortetracycline, or tetracycline in the feed. However, a recent study found that all isolates of C. jejuni associated with ovine abortion in the US are resistant to tetracycline . This is not true for Campylobacter fetus ssp. fetal abortions in the UK however, for which tetracylines are still widely used and resistance is unconfirmed.
