抄録: A study was conducted in 24 gilts to determine the effect of Trypanosoma brucei infection on their reproductive efficiency. The infected gilts developed clinical trypanosomosis following a prepatent period of 2-3 days with 1.8 x 10⁶ trypanosomes per gilt. The clinical signs were observed intermittent fever, pale mucus membranes, short moist cough, moist rales, mucopurulent ocular discharges and hyperemia of the skin, reduced feed intake, and loss of body condition, recumbency, uncoordinated movements, posterior paresis and death of gilts. The cause of death in the pigs was pneumonia caused by Escherichia coli. Grossly, the lungs were severely congested and had undergone gray hepatization. Histopathologically, the lungs had thickened and congested alveolar walls, and were infiltrated by mononuclear cells which were noticed more in the lung parenchyma. The role of secondary bacterial infection in the pneumonia observed, orchestrated by immunosuppression, which is a classical attribute of trypanosome infection is discussed.
