Full textThe Human African Trypanosomiasis is a neglected tropical disease prevalent in sub-Saharan Africa mainly in remote rural with poor access to health care. Available treatments are expensive and require significant human and logistical resources. Despite the lack of skilled health workers in endemic areas, people often fall back on to traditional medicine. Therefore investigating for new molecules seems necessary to contribute to the effort of research for alternatives therapies against HAT. In vitro, medicinal plants from the combretaceae family in Central African Republic showed trypanocidal activity on T. brucei brucei.Several cases of human infection with trypanosome parasites of animals have also been reported. The number of infections is probably underestimated. Some are usually cured in a spontaneous way, others require therapeutic care. Conventional drugs available against the THA, NECT combination and fexinidazole in clinical trial phase proved to be effective against T. lewisi (natural parasite of rats, causing atypical human Trypanosomosis) in vitro compared with T. brucei gambiense and in vivo in rats. Finally, the level of serum arginase, enzyme associated with the THA, is high in Trypanosomosis patients compared to healthy subjects from the same area. This rate is back to normal after effective treatment. Thus, the assessment of serum arginase may be considered as a biomarker for monitoring the effectiveness of treatment

Full textHuman African trypanosomiasis (HAT) or sleeping sickness is a re-emerging disease responsible for a major public health problem. Knowledges about its physiopathology are necessary to find out new therapeutics but few studies are available. There is an urgent need to work with new experimental models to test trypanocidal activity of new drugs. In this work, we tested first megazol in Trypanosoma brucei brucei-infected sheep and its pharmacokinetics in uninfected sheep. Results showed megazol is efficient to treat stage I of trypanosomiasis in sheep if oral absorption occurs properly but this parameter seem to be very variable. Then, megazol was tested in T. B. Gambiense-infected African green monkeys in order to find out the optimal dosing. The results should be completed by further studies with more animals and with non mutagenic megazol derived compounds. Combination of two trypanocidals, DFMO and nifurtimox, bas been tested at low dosing in infected African green monkey. DFMO associated to nifurtimox given per os during 8 or 15 days couldn't cure the all animals. These results should be explained by a pharmacokinetics study of the combination. In a further study, we tested trypanocidal activity of methylene blue in vitro and in vivo. We obtained IC50 suggesting methylene blue could be active on trypanosomal infections. However, methylene blue given per os or intra-peritonealy couldn't cure infected mice. Several hypothesis are discussed and deserve to be verified. In an other hand, we tried to find out new criteria more precoce and specific for the stage diagnostic. We first adapted the method of flow cytometry to analyse blood and cerebrospinal fluid of infected patients and ensure its utility to study sleeping sickness. Then, we reproduce the experiment in infected African green monkeys to analyse the lymphocytes subset in blood and cerebrospinal fluid every two weeks. Results showed an increase in lymphocytes B during the disease course. African green monkey could be a good immunological model of the disease to precise these first results and to develop a field test for stage diagnosis

Full textArginase induction, a mechanism of immunomodulation elaborated by trypanosomes has been identified. To avoid cytotoxic classical M1 macrophage activation, trypanosomes induce alternative M2 macrophage activation, which leads to L-ornithine production, essential for parasite growth. This immunomodulation pathway has been evidenced in a natural murine trypanosomiasis provoked by Trypanosoma musculi. This mechanism is also evidenced in human African trypanosomiasis (HAT). An increase in serum arginase is measured in HAT patients. A return to normal values is obtained after an efficacious treatment. Trypanosoma brucei gambiense, the causative agent of HAT, induces arginase in mouse macrophages and human leucocytes. T. lewisi, a rat parasite, also induces macrophage arginase.During host-parasite co-evolution, extracellular trypanosomes have selected a growth promoting mechanism, macrophage arginase induction by excreted secreted factor (ESF). We have produced a monoclonal antibody which inhibits trypanosome-induced arginase. This antibody blocks in vitro and in vivo T. musculi-induced arginase. Its injection into infected mice provokes a decrease in parasite load. This monoclonal antibody has allowed the identification of an orphan kinesin as the arginase inducing factor. The arginase inducing region of kinesin seems conserved among extracellular trypanosomes. Kinesin binds to macrophage membrane receptors. In vitro, addition of mannose to macrophage-parasite cocultures blocks arginase induction and parasite multiplication. Mannose injection decreases parasite load in infected mice. Compared to WT mice, parasite load is highly reduced in infected Mrc1 -/- KO mice. In trypanosomiasis, molecules targeting arginase pathway and/or mannose receptor, highly conserved in evolution, might represent new therapeutic approaches

Full textIn this thesis the knowledge gaps and the requirements for an evidence-based decision making in the field of tsetse and trypanosomoses are identified, with a focus on georeferenced data and Geographic Information Systems (GIS). Datasets, tools and analyses are presented that aim to fill some of the identified knowledge gaps.
For the human form of the disease, also known as sleeping sickness, case detection and treatment are the mainstay of control, so that accurate knowledge of the geographic distribution of infections is paramount. In this study, an Atlas was developed that provides village-level information on the reported occurrence of sleeping sickness. The geodatabase underpinning the Atlas also includes the results of active screening activities, even when no cases were detected. The Atlas enables epidemiological maps to be generated at a range of scales, from local to global, thus providing evidence for strategic and technical decision making.
In the field of animal trypanosomosis control, also known as nagana, much emphasis has recently been placed on the vector. Accurate delineation of tsetse habitat appears as an essential component of ongoing and upcoming interventions against tsetse. The present study focused on land cover datasets and tsetse habitat. The suitability for tsetse of standardized land cover classes was explored at continental, regional and national level, using a combination of inductive and deductive approaches. The land cover classes most suitable for tsetse were identified and described, and tailored datasets were derived.
The suite of datasets, methodologies and tools presented in this thesis provides evidence for informed planning and implementation of interventions against African trypanosomoses at a range of spatial scales.

Full textThis thesis aimed at identifying genetic markers associated with tolerance / sensitivity of cattle to African trypanosomosis. Association studies between microsatellite markers and trypanotolerance phenotype (anaemia control) were performed on a crossbred Baoule/zebu peul cattle population in natural conditions in south-western Burkina Faso. For genotyping, we used microsatellite markers located in four QTL (Quantitative Trait Loci) regions previously identified as related to anaemia or parasitaemia control in N'Dama / Boran zebu crossbred population. The linkage disequilibrium (LD) was estimated with D', r' and χ'² measures from genotype and haplotype data. Results showed high genetic variability in terms of mean number of alleles per locus, heterozygosities and the LD extends over shorter distances than what has been observed in selected European bovine populations. The ANOVA test showed that an allele of MNB-42 microsatellite marker was significantly associated with this phenotype (FDR = 0. 011). The search for signatures of selection performed on African trypanotolerant taurine, African trypanosusceptible zebu and European trypanosusceptible taurine, using tests based on the reduction of the microsatellite markers variability between trypanotolerant cattle and trypanosusceptible cattle in one hand and tests based on genetic differentiation on the other hand, allowed the detection of outliers (markers that deviate from the assumption of neutral evolution) that are probably linked to selected loci. Our results support the hypothesis that natural selection contributed to the development of trypanotolerance in West African taurine populations

Full textAnimal African Trypanosomosis (AAT) is a parasitic disease (trypanosome) with vectorial transmission (tsetse fly). In sub-Saharan Africa, it constitutes a major impediment to livestock development. However, there are trypanotolerant taurine cattle breeds capable of tolerating the disease. European and indicine breeds are trypanosusceptible and, without treatment, usually die from infection. PhD objectives are to improve knowledge of host-parasite interactions by identifying the genes, gene networks, metabolic pathways, and biological functions associated with trypanotolerance. Five West African cattle breeds have been experimentally infected with Trypanosoma congolense. RNA-seq libraries were constructed from blood samples to characterize the metatranscriptome during infection (bovine + parasite). The main findings reveal that the infection had a major impact on the transcriptome of cattle leukocytes regardless of breed. The results generally confirm the data from the literature including early activation of the innate immune response, followed by activation of the humoral response and inhibition of T cells in the chronic stage of infection. New results could be highlighted as a strong disruption of metabolism and energy production in the host. The N'Dama (trypanotolerant reference) breed showed an earlier and more intense immune response associated with strong activation of energy production by the cells. The Zebu breed (trypanosusceptible reference) showed a strong disruption of lipid metabolism, probably due to spoliation by the parasite or directly related to deregulation of the host metabolism. In conclusion, I was able to highlight subtle differences in some pathways related to the activation of the immune response, and highlighted the interactions between immune response, metabolic changes, and parasite-induced disturbances. These interactions metabolism * immune response deserve further study in cattle, to improve the treatment of trypanosomoses
