This study describes an outbreak of Toxoplasma gondii abortions in a sheep herd in January/February 2010. An aborted fetus was submitted to the Veterinary Diagnostic Laboratory for post mortem evaluation. Tissue samples were collected and processed by routine histological methods, stained by hematoxylin-eosin and by immunohistochemistry using anti-T. gondii and Neospora caninum specific antibod...

Chlamydiosis is one of the major diseases that can lead to abortion in ewes. Since 1997, in 5 regions of Tunisia, Chlamydia-related abortions have been reported in 15 sheep and goat flocks. One hundred and sixty-six sera and 50 vaginal swab samples were collected from adult ewes. Chlamydial antigens were detected in 29 (58%) of the vaginal swabs using Enzyme Linked Immunosorbent Assay (ELISA) w...

BACKGROUND The epidemiological situation of ovine chlamydial infections in continental Europe, especially Germany is poorly characterised. Using the German state of Thuringia as a model example, the chlamydial sero- and antigen prevalence was estimated in thirty-two randomly selected sheep flocks with an average abortion rate lower than 1%. Seven vaccinated flocks were reviewed separately. RE...

contagious agalactia (ca) is a serious disease syndrome of sheep and goats that is characterized by mastitis, arthritis, keratoconjunctivitis and, occasionally, abortion. mycoplasma (m.) agalactiae is the main cause of the disease in sheep and goats. the aim of the present study was to detect m. agalactiae in conjunctival, synovial fluid, nasal, ear and milk samples in sheep herds with or wi...

Three live vaccine candidates of Salmonella enterica subspecies I serotype Abortusovis (aroA, cya crp cdt, and plasmid-cured strains) have been developed, and their efficacies in inducing humoral antibodies and protecting against abortion after challenge with wild-type strain SS44 were evaluated in sheep. Following estrus synchronization, animals were immunized 3 weeks after fertilization and b...

infection by the protozoan parasite toxoplasma gondii, is widespread in humans and many other species of warm-blooded animals. it can cause significant morbidity and mortality in the developing fetus and in immunocompromised individuals, including humans with acquired immunodeficiency syndrome - aids or submitted to cancer chemotherapy. among livestock, sheep and goat are more widely infected w...

This paper reports on a sporadic, naturally acquired infection of sheep with Brucella abortus on a privately owned farm in Toro near Bauchi, Nigeria. The abortions, which occurred in a flock of 28 Yankassa sheep, involved five ewes at the third month of gestation. Serum and milk samples from the flock were examined for Brucella antibodies by the Rose Bengal plate test, serum agglutination test ...

Two hundred and fifty five biological samples were collected from 188 animals (81 sheep and 107 goats) during the lambing season from September 2009 to April 2010 from the Mafraq region of Jordan. Sampled animals belonged to 93 sheep and goat flocks that had abortion cases in the region. One hundred and seven (41.9%) biological samples were positive for the omp2 primers that were able to identi...
