The catalytic domains of two closely related cysteine proteinases (CP l and CP2) from Trypanosoma congolense, referred to as Cl and C2, were expressed as proforms in Escherichia coli (C 1) and in the baculovirus system (C I and C2). While the bacterial expression system did not allow recovery of ...

Congopain and cruzipain, the major cysteine proteinases from Trypanosoma congolense and Trypanosoma cruzi, were compared for their activities towards a series of new, sensitive fluorogenic substrates of the papain family of cysteine proteinases and for their sensitivity to inhibition by cystatins...

Memory T- and B-cell responses to trypanosome antigens were measured in peripheral blood mononuclear cells, spleen and lymph node cells obtained from 4 trypanotolerant N'Dama cattle which had been exposed to 6 experimental infections with Trypanosoma congolense. These cattle were treated with try...

Trypanosomosis is one of the major constraints on animal production in areas of Africa which have the greatest potential for significant increases in domestic livestock populations and livestock productivity. While the eradication of trypanosomosis from the entire continent is an unrealistic goal...

Susceptibility and immune responses of Zebu and Taurine cattle of West Africa to infection with Trypanosoma congolense transmitted by Glossina morsitans centralis
Approximately 320 East African Zebu cows over 36 months of age were monitored monthly from 1986 to 1992 in nine village herds in an area of high trypanosomiasis risk in southwest Ethiopia where there was resistance to all available trypanocidal drugs. Cows were individually treated with diminazen...

Effects of trypanosomiasis on reproduction of East African Zebu cows exposed to drug-resistant trypanosomes
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 ...
