A total of 240 blood samples of different breeds, sexes and ages of cattle were collected from randomly selected herd and analyzed in laboratory using wet, thick, thin smear and Buffy coat concentration techniques. The infection rate was 26.67%. The prevalence obtained was 9.17% and 17.50% respectively of infected males and females. Key words: Prevalence Bovine Trypanosomiasis Nigeria INTRODUCTION km of this area could otherwise be suitable for Trypaliosomasis is the mine given to diseases environment if trypanosomiasis could be controlled. The which are caused by protozoa of the genus trypanosoma. limited data available indicates that the area infested with There are large numbers of species in the genus and they the tsetse flies has been increasing steadily since the are widely spread in nature. Almost all domestic animals, 1950’s [3]. many wild species and man are affected by one or more of There are about 30 species of Glossina which are the trypanosomes. capable of transmitting trypanosomes, 11 of which are Trypanosomiasis is a parasitic disorder in mammals know to occur in Nigeria infesting 80% of Nigeria surface that multiply in the blood stream, lymphatic vessels and area and all are known to be vectors of trypanosome tissues including the cardiac muscles and the central species infectious to domestic animals [4]. The most nervous system (CNS). common species in Northern Nigeria are Glossina This infectious disease is virulent, incurable, but not palpalis, Glossina tachnoides these species are contagious (except dourine, veneral trypanosome of associated with riverine, wood vegetation and stream equines). Trypanosomes are frequently found in the areas. While Glossina Morsitans, Glossina Longipalis are blood of various animal species in many regions of the associated with Savannah regions. world. But despite the absence of the biological vector The organism are transmitted by tsetse flies Glossina in the Sahel savannah vegetation zone, sporadic species causing the trypanosomiasis which is outbreaks have been reported in the area Nawathe et al. characterized by parasitaernia, emaciation reduced [5]. productivity and frequently high mortality [1]. The annual bulletin of National Institute of FAO [2] stated that tsetse flies (Vector of Trypanosomiasis Research (N.I.T.R) indicated the trypanosomiasis) infest approximately 10 million km of presence of Glossina species in many states of the 2 Africa, representing 37% of the total continental land country including Adamawa State.
