Assessment of animal African trypanosomiasis (AAT) vulnerability in cattle-owning communities of sub-Saharan Africa [PDF]

, 2016
Background: Animal African trypanosomiasis (AAT) is one of the biggest constraints to livestock production and a threat to food security in sub-Saharan Africa.

La culture du tournesol en Afrique tropicale [PDF]

Tropicultura, 1983
Sunflower cultivation in tropical Africa. An inquiry carried out in Guinea has revealed that the disappearance of trypanotolerance within some local N'Dama cattle can not be attributed to the vaccination campaign initiated against infectious bovine ...

Trypanosomiasis and trypanotolerance in cattle: A role for congopain?

Parasitology Today, 1994
A Trypanosoma congolense cysteine protease (congopain) elicits a high IgG response in trypanotolerant but not in trypanosusceptible cattle during primary infections. As discussed here by Edith Authié, this observation suggests that congopain, like other parasite cysteine proteases, may play a role in pathogenicity and that more efficient immune ...

Trypanosoma congolense:B-Lymphocyte Responses Differ between Trypanotolerant and Trypanosusceptible Cattle

Experimental Parasitology, 1996
Trypanosomiasis is a serious constraint to livestock production in sub-Saharan Africa. Some breeds of cattle are genetically more resistant to the pathogenic effects of trypanosome infection. We measured B-cell activation and the quantity and isotype of antibody produced at the cellular level in six trypanotolerant N'Dama and five trypanosusceptible ...

Ly6C- Monocytes Regulate Parasite-Induced Liver Inflammation by Inducing the Differentiation of Pathogenic Ly6C+ Monocytes into Macrophages.

PLoS Pathogens, 2015
Monocytes consist of two well-defined subsets, the Ly6C+ and Ly6C- monocytes. Both CD11b+ myeloid cells populations have been proposed to infiltrate tissues during inflammation.

Transcriptional profiling of cattle infected with Trypanosoma congolense highlights gene expression signatures underlying trypanotolerance and trypanosusceptibility

BMC Genomics, 2009
Background African animal trypanosomiasis (AAT) caused by tsetse fly-transmitted protozoa of the genus Trypanosoma is a major constraint on livestock and agricultural production in Africa and is among the top ten global cattle diseases impacting on the ...

Understanding bovine trypanosomiasis and trypanotolerance: the promise of functional genomics

Veterinary Immunology and Immunopathology, 2005
African bovine trypanosomiasis, caused by the protozoan parasite Trypanosoma congolense, is endemic throughout sub-Saharan Africa and is a major constraint on livestock production. A promising approach to disease control is to understand and exploit naturally evolved trypanotolerance.
