Abstract
Control programmes for African animal trypanosomiasis (AAT) in livestock have been mainly focused on cattle with very little focus on goats, an important reservoir for the disease. Using the polymerase chain reaction (PCR), this study investigated trypanosome infection in village goats in Mambwe, a rural District in Eastern Zambia. Filter paper blood spots were collected from 326 goats and tested for infection with Trypanosoma congolense, Trypanosoma vivax and Trypanosoma brucei s.l. using ribosomal RNA internal transcribed spacers (ITS)-PCR. The frequency of trypanosomes from the sampled goats was 4.6% (95% CI = 2.3-6.8). Results indicated significantly high infections with Trypanosoma vivax (4.0%; 95% CI = 1.9-6.1) than T. congolense (0.6%; 95% CI = - 0.2 to 1.5), and T. brucei (0.0%), P = 0.04. Findings show the circulation of trypanosomes that causes AAT in goats and that they may pose serious threats to not only goats but also to other livestock reared alongside goats.
