The prevalence of brucellosis and bovine tuberculosis in ruminants in Sidi Kacem Province, Morocco.

Bovine tuberculosis (BTB) and brucellosis are major endemic zoonoses in ruminants in Morocco that impact on both animal and human health. This study presents an assessment of the epidemiological and socioeconomic burden of bacterial zoonoses in Sidi Kacem Province in Northern Morocco from a cross-sectional survey of 125 cattle and/or small ruminant-owning households. In total, 1082 sheep and goats were examined from 81 households.

No gold standard estimation of the sensitivity and specificity of two molecular diagnostic protocols for Trypanosoma brucei spp. in Western Kenya.

African animal trypanosomiasis is caused by a range of tsetse transmitted protozoan parasites includingTrypanosoma vivax, Trypanosoma congolense and Trypansoma brucei. In Western Kenya and other parts of East Africa two subspecies of T. brucei, T.

Factors affecting trypanosome maturation in tsetse flies.

Trypanosoma brucei brucei infections which establish successfully in the tsetse fly midgut may subsequently mature into mammalian infective trypanosomes in the salivary glands. This maturation is not automatic and the control of these events is complex. Utilising direct in vivo feeding experiments, we report maturation of T.

Trypanosoma brucei MOB1 is required for accurate and efficient cytokinesis but not for exit from mitosis.

Two MOB1 genes, MOB1-A and MOB1-B, were identified in Trypanosoma brucei. MOB1-A of T. brucei was shown to form a complex with TbPK50, a functional homologue of the Schizosaccharomyces pombe protein kinase Orb6, and immune precipitated MOB1-A exhibited histone H1 protein kinase activity.

Theileria annulata: virulence and transmission from single and mixed clone infections in cattle.

Theoretically, parasite virulence should be higher for faster growing parasites, and higher in mixed infections compared to single-clone infections. Virulence should also be positively correlated to transmission rates. Theileria annulata provides a good model system for studying such hypotheses, as parasite replication causes harm to the host, and there is evidence suggesting that the genetic complexity of an infection might affect its virulence.
