We screened cattle and goats from the districts of Chama, Monze and Mumbwa in Zambia for animal African trypanosomes, Babesia bigemina and Theileria parva using PCRs; 38.1% of the samples tested positive for at least one of the parasite species. The most common parasite was Trypanosoma vivax (19.8%). Its incidence was significantly higher in goats than in cattle, (P&lt;0.05). B. bigemina was found in samples from all the three areas, making it the most widespread of the parasites in Zambia. Among the tested samples, 12.0% of the positive samples were mixed infections. There were significant differences in the infection rates of T. vivax (Mumbwa had a significantly higher infection rate [39.6%, P&lt;0.0001]), Th. parva (Monze had the only cases...

Preliminary studies on the effects of orally-administered Transforming Growth Factor-beta on protozoan diseases in mice
Provedor de dados: 19
Autores: Namangala, Boniface; Inoue, Noboru; Sugimoto, Chihiro; 井上, 昇.
Transforming growth factor beta-1 (TGF-β1) is a pleiotropic cytokine with both pro- and antiinflammatory properties, depending on its environment and concentration. The present study evaluated the effects of orally-delivered TGF-β1 on mice parenterally-infected with various protozoan parasites. We report that while orally-administered TGF-β1 seems to confer partial protection against murine chronic babesiosis and acute trypanosomosis, no beneficial clinical effects were observed against acute babesiosis, malaria or toxoplasmosis. Taken together, these preliminary data suggest that the systemic effects conferred by exogenous TGF-β1 could be parasite speciesspecific. The variations in different parasitic infections could be due to (i) intrinsic differences...

Loop-mediated isothermal amplification (LAMP) assays for detection of Theileria parva infections targeting the PIM and p150 genes
Provedor de dados: 19
Autores: Thekisoe, Oriel M.M.; Rambritch, Natasha E.; Nakao, Ryo; Bazie, Raoul S.; Mbati, Peter; Namangala, Boniface; Malele, Imna; Skilton, Robert A.; Jongejan, Frans; Sugimoto, Chihiro; Kawazu, Shin-Ichiro; Inoue, Noboru.
We have developed two loop-mediated isothermal amplification (LAMP) assays for the detection of Theileria parva, the causative agent of East Coast fever (ECF), an economically important cattle disease in eastern, central and southern Africa. These assays target the polymorphic immunodominant molecule (PIM) and p150 LAMP genes. The primer set for each gene target consists of six primers, and each set recognises eight distinct regions on the target gene to give highly specific detection of T. parva. The detection limit of each primer set is 1 fg, which is equivalent to one copy of the PIM and p150 T. parva genes. These PIM and p150 LAMP primer sets amplify DNA of T. parva isolates from cattle and buffalo from different countries including Kenya, South...
