Abstract:

Eight horses exposed to both Trypanosoma congolense- infected and non-infected tsetse flies ( Glossina pallidipes) were examined daily for a period of 12 weeks. Three types of skin reactions were observed. These included local inflammatory skin reactions, which developed 1-2 days after the tsetse bites, and were evident in 5 infected horses and one uninfected. As these initial swellings regressed, further skin reactions (chancres) developed in the 6 horses bitten by T. congolense infected tsetse. The chancres were observed 6-12 days post-infection. In addition, 3 infected horses developed a third type of skin reaction, namely urticaria, on days 51, 67 and 71 post-infection. Histological examination was done of skin biopsies taken from all three types of skin reactions and they revealed different cell types. These were predominantly neutrophils in the initial skin reactions, lymphocytes in the chancres, and eosinophils in the urticaria. The skin lesions observed in the T. congolense infected horse have not been well documented elsewhere, particularly with regard to the histological picture. The first two lesions also occur early in the course of infection, while all three are of brief duration, hence are often missed.
