Brucella is ┙-Proteobacteria causing an infectious disease in mammals that could be transmitted to humans. Ruminant and swine are prone to be infected by such microorganism all over the world, thus acting as a potential reservoir for domestic livestock and therefore, affecting humans. Brucella species differ in their hosts’ preference, physiological abilities and cell surface structural charact...

A total of 10,818 domestic ruminants (3913 cattle, 2722 sheep, 3779 goats, 404 dromedaries) slaughtered in various abattoirs in Tunisia between 2003 and 2010 were examined for the presence of Echinococcus granulosus hydatid cysts. The prevalence of cystic echinococcosis (CE) was 16.42% in sheep, 8.56% in cattle, 5.94% in dromedaries and 2.88% in goats. CE prevalence increased with age according...

McCULLY, R. M. & KRUGER, S. P. Observations on bilharziasis of domestic ruminants in South Africa. Onderstepoort J. vet . Res. 36 (1), 129-162 Bilharziasis of 100 sheep and 14 cattle caused by Schistosoma mattheei Veglia & Le Roux, 1929, was studied in detail from the histopathological aspect. The ovine cases included natural as well as experimentally infested animals. The most significant chan...

Growth factors of endocrine and/or paracrine origin play determinant roles in antral follicular development. They modulate survival, proliferation and differentiation of follicular cells, acting in interaction with gonadotropins. It is thought that factors belonging to the families of the insulin-like growth factor (IGF-I and -II), epidennal growth factor (EGF and TGF-a) and fibroblast growth f...

Similarities as well as differences across species in the control of sexual behavior are helping to fully understand the subtle relations between physiology and eco-ethological constraints and how the brain integrates such information. We will illustrate this with sexual behavior in domestic ruminants and especially ewes. Females of these species like humans, but unlike rodents, have a long lut...

Infections with pestiviruses occur in cattle, sheep, pigs and also in numerous other ungulate species. In the present study, pestiviruses from goat, buffalo, deer and giraffe were analysed at the molecular level; unusual strains from cattle and pigs were also included. A phylogenetic analysis of the respective pestiviruses was undertaken on the basis of a fragment from the 5' noncoding region a...

Gross anatomy of the fetlock joint of the seven male adult onehumped camels were studied. In present study, the tendinous middle interosseous muscle, interdigital intersesamoid and straight sesamoid ligaments were observed. However, there was no proximal interdigital ligament. In conclusion, we found that the gross anatomy of the ligaments in one-humped camel fetlock joint share remarkable simi...

DU PLESSIS, J. L. Pathogenesis of heartwater. I. C01vdria ruminantium in the lymph nodes of domestic ruminants. Onderstepoort f. vet. Res. (1970), 37 (2), 89-96. The intracellular replication of CoJPdria mminanti11111 (Cowdry, 1926) is described in reticulum cells of lymph nodes severa l days prior to the appearance of rickettsial colonies in vascular endothelial cells. This is suggestive of a ...

The introduction of livestock species in Europe has been followed by various genetic events, which created a complex spatial pattern of genetic differentiation. Spatial principal component (sPCA) analysis and spatial metric multidimensional scaling (sMDS) incorporate geography in multivariate analysis. This method was applied to three microsatellite data sets for 45 goat breeds, 46 sheep breeds...
