Final Technical Report. Research on the incidence, economic importance and causal agent(s) of bovine cerebral theileriosis in semi-arid pastoral livestock systems in Ngorongoro, Monduli and Simanjiro District in Northern Tanzania.
Bovine cerebral theileriosis (BCT) has been ranked as the highest disease priority by pastoralist communities in Northern Tanzania and is considered a severe constraint to increased livestock production. The study incorporated a participatory rural appraisal survey carried out from September - November 2001, followed by longitudinal studies in selected study sites, field monitoring and treatment of affected cases and collection of post-mortem samples at slaughter slabs in pastoral areas. Gross pathology and histo-pathology work was carried out in collaboration with Turin University. The planned outputs of this research programme were to confirm the incidence of the disease; to assess its true social and economic impact; and to record the presence of haemoparasites and other possible disease agents and risk factors. Appropriate control methods were to be developed based on a thorough understanding of the epidemiology of BCT.
