Planned Impact
This project will fill important knowledge gaps that are currently limiting the development of sustainable control strategies for animal African trypanosomiasis (AAT). Elucidating the mechanisms of T. congolense resistance to Isometamidium chloride (ISM), identifying a marker for diagnosis, and crucially better understanding the emergence and spread of resistance, as proposed in this study, are essential steps towards effective and sustainable control, including optimal use of novel drugs. We anticipate this project will enable and contribute to wider discussions on sustainable use of drugs in AAT control and help to drive this as a priority. Hence, the economic and societal impacts from this work include:
Impact on disease control policies for sustainable use of trypanocides, leading to impacts on livestock farming in developing countries through reducing detrimental effects of resistance emergence:
Ultimate beneficiaries of the project are subsistence farmers in sub-Saharan Africa, who are finding that current AAT treatments are no longer working, threatening their livelihoods and food security. Approximately 50 million cattle, plus millions of other livestock, are at risk of AAT in tsetse-infected across an area of ~10M km2. AAT impacts include reduced milk yields, meat production, fertility, and draught power as well as mortality, and are estimated to cost billions (US$) to the region annually - estimated at $2.5 billion to Eastern Africa alone. The disease severely impacts sub-Saharan regions where livestock rearing is the main livelihood of small communities, including many countries on the DAC list of least developed countries. Tanzania has the third largest livestock population in Africa, and a high proportion of poor livestock keepers, with >4 million cattle threatened by trypanosomiasis.
Livestock keepers currently use 35-70 million doses of trypanocides annually. Two primary options exist for treatment of AAT: Isometamidium chloride and Diminazene aceturate . Both drugs are >50 years old and reported resistance to them is widespread. Outputs from this project will provide local (veterinary services), national (Ministry of Agriculture, Livestock and Fisheries), global (AU-PATTEC, FAO) and donor (GALVmed, DFID, BMGF) organisations with evidence to back up decision-making on sustainable use of drugs in AAT control. This project was co-constructed with local veterinary services and livestock keepers in Serengeti District, and national decision-makers in Tanzania, who have identified effective and sustainable trypanocide use as a particular concern. The same trypanocide drugs used for AAT are also used to reduce T. brucei circulation in cattle, which can be reservoirs for human African trypanosomiasis. Sustainable use of these drugs therefore has added benefits in prevention of human disease.
Impact upon academic and industry AAT drug discovery and development programmes:
We know very little about how resistance emerges and spreads in livestock trypanosomes. This project will significantly advance this knowledge, both in terms of characterising mechanisms and rate of resistance emergence to ISM, and furthering our very scanty knowledge of the epidemiology of resistance in the field. The development of a mathematical model, that is developed and based on reliable data, will both inform on the dynamics of resistance and spread of ISM, and importantly be applicable to predicting resistance emergence and spread for novel trypanocides (such as the candidate compound currently under development by project partners GALVmed) - this output is a critical gap in knowledge and capability at present, which would be able to inform strategies to minimise resistance emergence and spread, and maximise the lifetime of both ISM and novel trypanocides. The applicants have links with relevant academic, industrial and policy stakeholders to enable dissemination and uptake of results in order to translate impact to farmers.

Pharma to farmer: field challenges of optimizing trypanocide use in African animal trypanosomiasis.
in Trends in parasitology
Description | Trypanocidal drugs are widely used in cattle in sub-Saharan Africa to treat and prevent trypanosomiasis. However, livestock keepers do not usually have access to diagnostics to confirm if trypanosomiasis is the cause of illness, and limited animal health systems mean that they often purchase and administer the drugs themselves. We monitored livestock keepers when they gave trypanocides to quantify the potential reasons for treatment failure, and followed up treated cattle to see how often treatment failed. Only 35% of samples taken at the time of treatment tested positive for trypanosomiasis. When the dose, route of administration, competence of administration and storage conditions were assessed, 52% of treatments were given appropriately. Both treatment failure and failure of prophylaxis were identified in animals that had been treated inadequately. Some failures were also identified in animals treated adequately, which could reflect issues of drug quality, or resistance, both factors we are still assessing. The approach used establishes a new technique for assessing treatment failures in farmer-led treatments. We held an international symposium "Symposium on African Livestock Trypanosomiasis" in Tanzania with participants from 18 different countries, bringing together all stakeholders involved in trypanocide usage and trypanocide resistance to develop plans for more sustainable and effective trypanosomiasis control. |
Exploitation Route | Outcomes from the project will help to inform national decision-making about Animal African Trypanosomiasis (AAT) control, as well as having implications for human disease risk. For example the outputs have already helped to inform the Tanzania National Strategy for Control of Human African Trypanosomiasis and Animal African Trypanosomiasis. The results will also help to inform international strategies for trypanosomiasis control. Specifically, they are helping to provide evidence for the FAO international guidelines on trypanocide use and trypanocide resistance, facilitated by the symposium and workshop organised by the project team. The scientific approaches developed here will be relevant to other research teams for assessing failures of trypanocidal drugs or other similar pharmaceuticals. |

The Symposium on African Livestock Trypanosomiasis, organised by the project team with FAO, has provided a turning point in the development of strategies for more effective and sustainable use of trypanocides. Engagement activities that we have conducted with farmers, including provision of an information sheet that clarifies common errors farmers make when administering trypanocides, has already helped farmers to change their behaviour for more effective trypanocide usage. |

Title | Longitudinal study design for quantifying trypanocide treatment failure in cattle |
Description | This project established a new methodological approach for assessing the success or failure of farmer-led trypanocidal treatments in a longitudinal study. This included monitoring treatment outcomes by microscopy and PCR, and creating algorithms to assign each treatment to failure or success, based on the results of follow up samples at different time points. |
Type Of Material | Physiological assessment or outcome measure |
Year Produced | 2023 |
Provided To Others? | Yes |
Impact | This approach was used in this project to generate data on the relative contributions of different factors (e.g. inappropriate dosing, incorrect diagnosis) on treatment failure. This data is novel and urgently needed to help inform better strategies for AAT control. A publication describing this approach is being prepared for submission. The approach has been presented at two meetings and the received positive feedback. |
Title | Data on the response to trypanocide treatments in cattle |
Description | Samples, sample testing results and related metadata originate from a longitudinal study conducted in Tanzania to quantify reasons for treatment failure when farmers administer trypanocides. Blood samples, preserved in Paxgene tubes to stabilise genetic material, were collected at the time of treatment, 1 week and 4 weeks later (for treatments with Diminazene and Homidium) and 8 weeks and 12 weeks later (when Isometamidium was given, to measure the extent of prophylaxis). DNA extracts are available from these samples, as well as PCR results. |

Results and Impact | Using findings from the first part of our study on the reasons that trypanocidal treatments fail, we produced an information sheet for livestock keepers on trypanosomiasis control, with clear simple information to help them avoid the most common issues with trypanocide use. The information sheet was shared with all the farmers that participated in our study and distributed to livestock field officers in Serengeti District, where the research took place. In addition, the information sheet was presented and distributed at two workshops held in other parts of Tanzania, Pangani District and Simanjiro District, where it was shared with farmers and livestock field officers. The information sheet and associated presentation was very well received, and all three districts requested more copies of the sheet to distribute further. Multiple farmers said they would change their behaviour regarding trypanocide use now they better understood how to use trypanocides effectively. |
