Abstract:
A recent cross-sectional survey of bovine trypanosomiasis at the Obudu Cattle Ranch (OCR), located at an altitude of 1576 m on the Obudu Plateau in Nigeria is presented. Blood samples from 68 adult cattle in three herds and 290 cattle (27 calves and 263 adults) in eight herds were screened for trypanosome infections in August 1989 and February 1990, respectively. Although the plateau is designated as tsetse-free, one (1.5%) (0.015, 95% confidence interval ±0.029) and four (1.4%) (0.014, 95% confidence interval ±0.013) of the ranch’s cattle in August and Febraury, respectively, had trypanomome infections. Trypanosoma brucei caused one of the infections while the others were caused by Trypanosoma vivax.
