A 69-kDa antigen of Trypanosoma congolense induces both IgM and IgG in experimentally infected cattle. Cloning and sequencing of the gene coding for this antigen revealed that it belongs to the heat shock protein 70 family (hsp70) and is homologous to mammalian immunoglobulin binding protein (BiP...

Nineteen herds of cattle (N'Dama, Baoule and Zebu crosses) and 20 flocks of Djallonke and Djallonke x Sahel sheep in the region of Boundiali, northern Cote d'Ivoire, were monitored monthly for body weight, packed red blood cell volume and the presence of trypanosomes in blood over various periods...

Effect of tsetse control with insecticide-impregnated traps on trypanosome prevalence and productivity of cattle and sheep in northern Cote d'Ivoire
Trypanotolerance involves an ability to both control trypanosome multiplication and resist the pathogenic effects of trypanosome infection. Studies in the African Trypanotolerant Livestock Network and elsewhere have shown that the latter capacity is more closely correlated than the former to the ...
Infections of cattle with tsetse-transmitted Trypanosoma congolense are accompanied by antibody responses to the variable surface glycoprotein (VSG) and to two major invariant antigens, a member of the hsp 70 family and a 33KDa cysteine protease. During primary infection, trypanotolerant N'Dama (...

Bovine T-cell responses to defined Trypanosoma congolense antigens during infection
Bovine trypanosomiasis is prevalent in southwest Ethiopia infested with tsetse flies. Since 1986, East African Zebu cattle raised under trypanosomiasis risk in the Ghibe Valley of southwest Ethiopia have been studied to investigate the effects of trypanosmiasis on health and productivity. Approxi...

Variations in susceptibility to the effects of trypanosmiasis in East African Zebu cattle
The trypanosome surface coat is composed almost entirely of a homogeneous array of molecules known as variable surface glycoproteins (VSG). These molecules are highly immunogenic and elicit a strong antibody response in the infected host. Antibodies against the surface-exposed epitopes of a parti...
