During an experimental chronic infection of inbred mice with Trypanosoma congolense several physiological parameters become altered. Splenomegaly followed later by hepatomegaly are predominant. Lactate dehydrogenase and aminotransferase activities of the plasma are elevated, the number of erythrocytes and thrombocytes decreases, whereas monocytic cells are detected in higher concentrations. Gamma-Globulins and transferrin become elevated. Some of the pathobiochemical alterations depend directly on the parasitaemia and are reversed to normal values after chemotherapy with diminazene aceturate (Berenil). The curative effect of this drug depends largely on when it is administered. In acute T. congolense infections, leading to the death of the animals in 3-4 days, pathobiochemical alterations are found only shortly before the exitus.

The infection of Yankassa rams with three important trypanosome species affecting livestock, namely, Trypanosoma congolense, T. vivax and T. bruceiproduced both acute and chronic fatal conditions. Chronic infections were induced in the three infections by the application of subcurative doses of diaminazene aceturate (Berenil). Pathological changes in the infected animals included splenomegaly and hepatomegaly which were more pronounced in acute than in chronic T. congolense infection. However, these changes were more severe in chronic than in acute T. vivax infection. While splenomegaly was more pronounced in chronic T. bruceiinfection than in acute, hepatomegaly and lymphadenopathy were more severe in acute than in the chronic condition. The increases in size of the spleen, lymph nodes and liver were associated with congestion, increases in cell density related to increased immunological reactions in the spleen and lymph nodes as well as increase in numbers, size and activity of the phagocytic cells in these organs.
