Allegye-Cudjoe, E.Vitouley, H.Randolph, Thomas F.Diall, O.Sidibe, I.Mahama, C.I.[Field detection and evaluation of trypanocidal drug resistance in the Sissala East District of northern Ghana]Field detection and evaluation of trypanocidal drug resistance in the Sissala East District of northern Ghana

In light of the current problems and limitations of chemotherapy for trypanosomiasis in domestic livestock and human beings, this workshop was conducted to discuss research aimed at developing new trypanocides. Because of the scarcity of information on the phenotypic and genetic basis of drug res...

The high prevalence of resistance of Haemonchus contortus to all major anthelmintic groups has prompted investigations into alternative control methods in South Africa, including the use of copper oxide wire particle (COWP) boluses. To assess the efficacy of COWP against H. contortus in indigenou...

A survey to investigate resistance to drugs used in the treatment of bovine trypanosomosis was conducted in the eastern province of Zambia between 1996 and 1998. A cross-sectional study was conducted in three districts (Petauke, Katete, Lundazi) at 34 village sampling sites selected at random fr...

Trypanocidal drugs are the most commonly purchased and used livestock input by resource-poor farmers in sub-Saharan Africa. The effective use of trypanocidal drugs by smallholder farmers is threatened by the development of widespread resistance. This is a particular concern for smallholder crop-l...

Field studies were conducted to assess the occurrence of resistance to isometamidium chloride and diminazene aceturate in trypanosomes infecting cattle in Kenedougou Province of Burkina Faso. Forty-five of the 166 villages in Kenedougou were randomly sampled and visited to assess livestock numb...
