Book (series)Choice of Technique for Creating Tsetse-Free Zones in Africa: The Cost Dimension 2007
Also available in:
No results found.African trypanosomiasis, the parasitic disease caused by trypanosomes transmitted by tsetse flies to people and their livestock throughout much of sub-Saharan Africa, is widely recognised as having had a major impact on the development of the continent, in particular on the distribution of its livestock and, sometimes, its human, populations. Today it continues to cause epidemics in human populations, where the disease is always fatal if left untreated, and to leach away the resources of Africa’ s livestock keepers, obliging them to spend substantial sums on trypanocides to prevent or treat the disease, while still lowering livestock productivity, increasing their death rates and limiting the use of animal traction. -
Book (series)Expert consultation on the sustainable management of parasites in livestock challenged by the global emergence of resistance
Part 2: African animal trypanosomosis and drug resistance: a challenge to progressive, sustainable disease control
2022Also available in:
No results found.African animal trypanosomosis is a vector-borne disease transmitted by tsetse flies and other vectors in 37 African countries. Affecting livestock health and welfare, the disease imposes a heavy burden on communities that rely on domestic animals for their livelihoods. In most endemic areas, trypanosomosis control relies heavily on trypanocidal drugs, which are often the only tool farmers possess to manage the problem. Unfortunately, the few veterinary medicines to treat or prevent the disease are old and outdated, and their efficacy is challenged by the emergence and spread of resistant trypanosome strains. FAO convened experts to discuss how to control African animal trypanosomosis progressively and sustainably in the face of drug resistance. FAO organized the meeting in the framework of an Expert Consultation on the sustainable management of parasites in livestock challenged by the global emergence of resistance. The experts of animal trypanosomosis warned that over 17 countries in Africa have reported treatment failure possibly resulting from trypanocidal drug resistance, which hampers disease control and negatively affects food security and livelihoods. Several factors contribute to the emergence and spread of trypanocidal drug resistance, including drug overuse and misuse, the circulation of fake or substandard products and weak controls along the supply chains. The meeting recommended that national authorities should promote the quality control of trypanocides, raise awareness of rational drug use and strengthen data collection and surveillance. FAO and the other organizations of the Tripartite should develop and disseminate guidelines and best practices, provide a platform for technical and scientific discussions, and they should support advocacy, awareness and resource mobilization at the international level. Academic institutions should improve our understanding of the mechanisms and drivers of resistance and develop more effective tools to monitor and curb the spread of the problem. -
Book (series)Long-term tse-tse and trypanosomiasis management options in West Africa 2004
Also available in:
No results found.Tsetse-transmitted animal trypanosomiasis is a complex disease that directly and indirectly has an impact on Africa’s crop and livestock agricultural development. In this paper, state-of-the-art spatial tools are applied to study the variety of agro- ecological settings in West Africa with a view to providing decision support to the management of the tsetse and trypanosomiasis ( T& problem according to the prevailing agro- ecological conditions. Based on the analytical mapping of dominant lives tock systems, land- use patterns, integration of livestock and crop agriculture ( mixed farming) and geoclimatic factors affecting tsetse ecology ( northern dry band with fragmented tsetse populations and southern humid band where tsetse are widespread), priority areas for T& T intervention were identified. These areas are situated the northern band of the tsetse belt where: • tsetse populations are fragmented ( and therefore vulnerable) or confined only to suitable vegetation along main river courses; • fly reinvasion risk is minimal due to land pressure and adverse climatic conditions for tsetse; and • integration of crop and livestock agriculture prevails. In these areas, the elimination of the fly and the disease may be achievable and consolidated through the expansion and intensification of mixed farming, leading to maximal yield benefits when expressed in terms of sustainable agriculture and rural development.
