Abstract


          In order to identify circulating trypanosomes in Kinshasa, Mbanza Ngungu, Masi Manimba and Mushie domestic animals and to determine their prevalence by PCR, a longitudinal study was conducted. 1653 blood samples were collected from domestic animals in the Kinshasa, Mbanza Ngungu, Masi Manimba and Mushie households, of which 22 were positive for Trypanosoma congolense Forest, corresponding to a gross prevalence of 1.3%. As for households, Kinshasa had a prevalence of 2.5%, Mbanza Ngungu a prevalence of 2.4%, Masi Manimba without any prevalence and Mushie a prevalence of 1.3%. In relation to the seasons, the rainy season had a prevalence of 1.4%, while the dry season had a prevalence of 1.3%. The difference was significant (Khi2 = 0.0144, P = 0.904 ? 0.05). Regarding species, cattle had a prevalence of 0.9%, pigs a prevalence of 3.7%, sheep a prevalence of 1.4% and goats a prevalence of 0.7%. As for sex, males had a prevalence of 0.9%, while females had a prevalence of 1.5%. The difference was significant (Khi2 = 0.9758 P = 0.323 ? 0.05) .This study showed that TAA is declining among animals in these four foci. Thus, clinicians in the field should reorient their therapeutic strategy, incorporating this new situation.
