Abstract

Adult were inoculated with a recently isolated strain of of human origin. The animals developed subacute to chronic infection and low-grade parasitemia. Histopathological examination of the heart revealed a severe pancarditis resulting in pronounced weight loss, and survival times of 5–8 weeks, preventing development of meningoencephalitis. In the brain a moderate meningitis was found, usually associated with moderate numbers of parasites in the choroid plexus and leptomeninges; however, trypanosomes were also found without tissue inflammation. Meningoencephalitis was found after 7 weeks, with parasites in the cerebral parenchyma. Chronic inflammation was present in lungs and kidney, often associated with trypanosomes; in one animal glomerulonephritis was found. Spleen and lymph glands showed a variable degree of lymphoid hyperplasia but no extravascular parasites. In the liver of all animals plasmolymphoid infiltrates were observed in the periportal connective tissue; no extravascular parasites were observed. A variable degree of lymphoplasmohistiocytic infiltrate in the connective tissue and occasional rare trypanosomes were seen in mesenterium, pancreas, epididymis, striated muscle, and skin. Experimental infection in appears to be a suitable model for study of the acute trypanosomiasis of , but not for chronic African sleeping sickness with cerebral involvement.
