A Spatio-temporal Model of African Animal Trypanosomosis Risk.

Background: African animal trypanosomosis (AAT) is a major constraint to sustainable development of cattle farming in sub-Saharan Africa. The habitat of the tsetse fly vector is increasingly fragmented owing to demographic pressure and shifts in climate, which leads to heterogeneous risk of cyclical transmission both in space and time. In Burkina Faso and Ghana, the most important vectors are riverine species, namely Glossina palpalis gambiensis and G.

Genetic diversity among Trypanosoma (Duttonella) vivax strains from Zambia and Ghana, based on cathepsin L-like gene.

Understanding the evolutionary relationships of Trypanosoma (Duttonella) vivax genotypes between West Africa and Southern Africa can provide information on the epidemiology and control of trypanosomosis. Cattle blood samples from Zambia and Ghana were screened for T. vivax infection using specie-specific PCR and sequencing analysis.

The sequential aerosol technique: a major component in an integrated strategy of intervention against Riverine Tsetse in Ghana.

Background: An integrated strategy of intervention against tsetse flies was implemented in the Upper West Region of Ghana (9.62°-11.00° N, 1.

Molecular epidemiological studies on animal trypanosomiases in Ghana.

Background: African trypanosomes are extracellular protozoan parasites that are transmitted between mammalian hosts by the bite of an infected tsetse fly. Human African Trypanosomiasis (HAT) or sleeping sickness is caused by Trypanosoma brucei rhodesiense or T. brucei gambiense, while African Animal Trypanosomiasis (AAT) is caused mainly by T.

Managing tsetse transmitted trypanosomosis by insecticide treated nets--an affordable and sustainable method for resource poor pig farmers in Ghana.

An outbreak of tsetse-transmitted trypanosomiasis resulted in more than 50% losses of domestic pigs in the Eastern Region of Ghana (source: Veterinary Services, Accra; April 2007). In a control trial from May 4(th)-October 10(th) 2007, the efficacy of insecticide-treated mosquito fences to control tsetse was assessed. Two villages were selected--one serving as control with 14 pigsties and one experimental village where 24 pigsties were protected with insecticide treated mosquito fences.
