Mechanisms controlling anaemia in Trypanosoma congolense infected mice por Noyes, H.A., Alimohammadian, M.H., Agaba, Morris, Brass, A., Fuchs, H., Gailus-Durner, V., Hulme, H., Iraqi, F.A., Kemp, Stephen J., Rathkolb, B., Wolf, E., Angelis, M.H. de, Roshandel, D., Naessens, Jan

“…Trypanosoma congolense are extracellular protozoan parasites of the blood stream of artiodactyls and are one of the main constraints on cattle production in Africa. In cattle, anaemia is the key feature of disease and persists after parasitaemia has declined to low or undetectable levels, but treatment to clear the parasites usually resolves the anaemia. …”
