It is one agent responsible for ovine campylobacteriosis or vibriosis, which causes disease in sheep and to a lesser extent in cattle and goats.
Infection in ewes can cause abortion in the last 6 weeks of pregnancy, premature lambing, stillbirths, fever, diarrhea, depression, and vaginal discharge before parturition. Campylobacter fetus is transmitted orally. It is very contagious in ewes that are confined. Once the ewe is exposed, the organism may move from the intestinal tract to invade the uterus and fetus. Fetal infection is common in the last 2 months of pregnancy.
It is another agent of ovine campylobacter abortion. In sheep Campylobacter jejuni causes placental and fetal infection, and in other species it causes enteritis and diarrhea. It has been occasionally associated with abortion in cattle and goats. A Campylobacter jejuni infection is nearly indistinguishable from a Campylobacter fetus infection. Since the symptoms are similar a culture should be taken to identify the causative agent.
Campylobacter fetus-jejuni Bacterin The bivalent Campylobacter vaccine that Hygieia Biological Labs makes contains the two types of Campylobacter mentioned above. The vaccine contains killed bacteria and is intended for use in breeding ewes to help prevent losses associated with late term abortion due to infection with Campylobacter fetus or Campylobacter jejuni. A 2 cc dose is administered SQ (subcutaneous - under the skin) at the side of the neck in front of the shoulder. Previously unvaccinated ewes and all yearling ewes should receive one dose immediately prior to breeding and a second dose at 3-4 months gestation. In subsequent years, previously vaccinated animals should receive a booster dose at 3-4 months gestation.
