“…Vaccines against Salmonella spp. are under development, with some already available [75,76]. García-Seco et al [76] found a new inactivated vaccine against S. abortusovis to significantly reduce the risk of abortion associated with infection, as well as bacterial shedding by infected ewes.…”

Introduction and Objective. Abortion can occur in sheep, among others, in response to bacterial infection. The present article reviews the latest reports on the various economic and health consequences for the herd, other animals and humans. Review methods. Two independent reviewers searched in PubMed and Google scholar (any date to September 2021) for studies concerning bacterial abortion in sheep. Keywords for the search strategy were: bacteria, sheep, and abortion. Papers were reviewed for scientific merit and relevance as well as for current information. Brief description of the state of knowledge. In the reviewed literature, much attention was paid to infections by Brucella spp., Campylobacter spp., Coxiella burnetti, Listeria spp., and Salmonella spp. As the presence of these bacteria varies according to region, any differential diagnosis should consider the most common pathogens in a given area. It also should be noted that most of the described pathogens have zoonotic potential and, as such, it is extremely important to observe safety rules when assisting in delivering births and when dealing with stillbirths. Conclusions. Identification of the etiological agent seems to be a key factor in the management of abortions, especially in flocks where their numbers appear to be increasing; this is needed to manage and control disease in the flock, and to protect humans and other animal species on the farm. Most studies use molecular methods as diagnostic tools, mainly PCR, and use both foetuses and placenta as research material.

Ovine abortion is a worldwide problem for sheep farmers, and can have a variety of infectious and non-infectious causes. The most notable infectious causes are Chlamydia abortus and Toxoplasma gondii, but there are a range of pathogens known to farmers and vets. Diagnosis is achieved by post-mortem examination of aborted lambs and testing of samples including, but not limited to, the foetal membranes and placenta. There are several efficacious vaccines available in the UK targeting abortion-associated pathogens, mainly to be administered before mating. Vaccine uptake is variable, and more emphasis on farmers complying with protocols needed.
