Synopsis (short abstract) Trypanocidal drugs remain the principal method of animal trypanosomiasis control in most African countries. However, there is growing concern that their future effectiveness may be severely curtailed by widespread drug resistance. This document presents an overview of the current situation of resistance to drugs for the chemotherapy of trypanosomiasis in African livestock. Although the number of case reports on drug resistance is increasing, there is a lack of reliable data at the regional or national level on the true prevalence and impact of drug resistance. In order to compare data on a temporal and spatial basis across Africa there is an urgent need for better standardization of tests for the detection of drug resistance. The advantages and disadvantages of the currently available assays are briefly reviewed and measures suggested to improve the situation. Finally, some guidelines on delaying the development of drug resistance are proposed and measures which may be adopted to control drug resistance when it occurs are recommended. Although there is still a lack of knowledge about the mechanisms of resistance and the factors responsible for the development of drug resistance, urgent measures are needed to maintain the efficacy of the existing drugs. Based on experiences of the control of resistance to other drugs such as antimalarials, antibiotics and anthelmintics it is suggested that reliance on the "sanative pair" guideline might not be sufficient to control resistance to trypanocides. This guideline needs to be accompanied by the following additional measures:

    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 Unfortunately, the few veterinary medicines to treat or prevent the disease are old and outdated, and their efficacy is challenged by the emergence and spread of resistant trypanosome strains.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.

    Guidelines resistance management and integrated parasite control in ruminants 2004

    Population growth, rapidly increasing urbanization and growth in income in developing countries are creating a tremendous increase in the demand for food of animal origin. This livestock revolution is demand-driven, illustrated by the fact that meat consumption in developing countries grew approximately three times more than it did in the developed world during the period from the early 1970s to the mid 1990s. During the same period the production of animal food products also grew most dramatically in the countries with the increased demand. In fact the meat production in developing countries, with the exception of sub-Saharan Africa, grew at more than five times the rate in the developed countries. The projections of the International Food Policy Research Institute (IFPRI) using IMPACT (International Model for Policy Analysis of Agricultural Consumption) are that the consumption of meat and milk in developing countries will grow by about 3 percent per year between now (2003) and 2020 (Delgado et al., 1999). It is likely that this will improve the livelihood of small and medium scale market oriented farmers but only if an enabling environment is created including access to credit, development of infrastructure and animal production and health services. Farmers need access to information regarding disease control and livestock management supporting their ability to decide where to invest their resources to increase production and productivity.
