Campylobacter infection is one of the major causes of ovine abortions worldwide. Historically, Campylobacter fetus subsp. fetus was the major cause of Campylobacter-associated abortion in sheep; however, Campylobacter jejuni is increasingly associated with sheep abortions. We examined the species distribution, genotypes, and antimicrobial susceptibilities of abortion-associated Campylobacter is...

Abortions and the economic losses they bring about is an important issue in sheep and goat husbandary. Despite many studies conducted on sheep and goats, the underlying reasons behind abortions could not be identified. In the present study, the role of immunologic factors in abortions seen among sheep and goats has been evaluated. The frequencies of anti-sperm antibodies (ASA), anti-zona pelluc...

Brucellosis is an economically important disease worldwide. Bangladesh has been reported an endemic area for brucellosis. The occurrence of brucellosis in people and the distribution of the disease among the livestock to be spatially related. A survey of brucellosis was carried out in sheep of Netrakona and Mymensingh districts of Bangladesh. A total number 102 blood samples were collected from...

A field study on the bacterial etiology of abortions among sheep and goats having migratory practices in the northwest hilly states of India was carried out. A total of 203 flocks were investigated. Abortion outbreaks occurred in 51 flocks and sporadic abortions occurred in 114 flocks. Vaginal swabs from aborted sheep and goats were collected and processed for isolation of bacterial agents from...

Border disease is a congenital viral disease of sheep and goats and cause significant economic losses worldwide. It may cause abortion in sheep. However, there isn’t any report of ovine abortion due to this virus from Iran. The aim of the present study was to investigate the role of this viral infection in sheep abortions in Chaharmahal and Bakhtiari province. To this end, 100 samples of aborte...

A study was carried out to investigate the frequencies of abortion and congenital Toxoplasma gondii infection within 27 families (765 individuals) of a pedigree Charollais sheep flock maintained on a working farm in Worcestershire, UK, since 1992. Pedigree lambing records were analysed to establish the frequency of abortion for each family. The frequency of congenital infection was determined f...

The aim of the study was to determine the seroprevalance of Chlamydophila abortus in aborting ewes and cattle in the Kars province in the north-eastern part of Turkey. Thirty sheep flocks and 26 herds of dairy cattle out of 4 districts in the province were examined by ELISA. For this purpose, abortion cases of 236 sheep and 192 cows of different breeds and age were investigated serologically du...

BACKGROUND Campylobacter jejuni is commonly found in the gastrointestinal tract of many food-animals including sheep without causing visible clinical symptoms of disease. However, C. jejuni has been implicated in ovine abortion cases worldwide. Specifically, in the USA, the C. jejuni sheep abortion (SA) clone has been increasingly associated with sheep abortion. In vivo studies in sheep (the na...

Toxoplasma gondii is an economically important parasite that can cause spontaneous abortion in sheep and humans. The importance of the different transmission routes of the parasite is unclear. However, three routes are recognised: (1) shedding of infective oocysts by the definitive host, the cat (2) consumption of undercooked, infected meat and (3) congenital transmission (mother to offspring)....
