Повний текст джерелаThis work presents an epidemiological and an ecological study of schistosomiasis in Benin. A synthesis of the epidemiological knowledge of schistosomiasis in the space of the Economic Community of West Africa States (ECOWAS) was carried out. Furthermore, in Benin, we confirmed the existence of the two human schistosomes : S. Haematobium and S. Mansoni on the five existing in the ECOWAS space in which Benin is located (S. Haematobium, S. Mansoni, S. Guineensis, S. Bovis and S. Curassoni). The prevalence obtained for S. Haematobium was 85% and that for S. Mansoni was 30%, and there was evidence for mixed human infections. We could find in Benin at least five potentially snail vector species : B. Forskalii, B. Globosus and B. Truncatus for S. Haematobium, B. Pfeifferi for S. Mansoni and I. Exustus, an exotic snail known to be the snail vector for S. Indicum, S. Spindale and S. Nasale in South-East Asia. I. Exustus is recorded for the first time in Benin in this work and no evidence of active transmission was made. The study of the snail-schistosome interactions showed that the different S. Haematobium populations were differently compatible with three of the four groups of Bulinus : the africanus group, the forskalii group and the reticulatus group and that the different S. Mansoni populations were equally compatible with B. Pfeifferi. The six life-history traits, parasite prepatent period, prevalence and cercarial production and snail growth, reproduction and survival were analyzed using five schistosome populations from Benin including three populations of S. Haematobium (Doh, Sô-Tchanhoué and Toho-Todougba) and two populations of S. Mansoni (Kpinnou and Toho-Todougba) and revealed that if the S. Haematobium populations seemed to be adapted to a local vector, this was not the case for the S. Mansoni populations. The study of the vertebrate-schistosome interactions revealed the existence of an infradian rhythm in the cercarial emissions of both S. Haematobium and S. Mansoni. The human behaviour, followed in one of the transmission sites (Toho-Todougba) where both schistosome species are present, was perfectly correlated with the schistosome chronobiology. This was interpreted in terms of adaptative strategy favouring the transmission of the parasite to its human host

Повний текст джерелаAgricultural ecosystems under seasonality are characterized by periodic host plant absence, which may impact parasite evolution. Sustainable crop protection must incorporate parasite evolution. This requires a long-term epidemiological perspective, which is hardly amenable to experimentation, and makes multi-annual plant epidemic models particularly relevant. We consider a family of such models, termed semi-discrete models, which correspond to distinct life cycles, depending on the parasite reproduction mode (sexual or asexual) and its primary infection mode (airborne or soilborne, i. E. With or without negative density-dependence, respectively). Under the assumption of a trade-off between in-season multiplication and season-to-season survival, an adaptive dynamics approach shows that temporal niche differentiation can lead airborne parasites to diversify and coexist. These results assume a strictly asexual parasite life cycle, which does not correspond to all plant parasites. Some parasites produce survival forms by self-incompatible sexual reproduction. When sexual reproduction is mandatory, the need to find a mate induces positive density dependence at low density (demographic Allee effects). Under the assumption of a trade-off between in-season asexual multiplication and resource allocation to sexual survival forms, we show that evolution may lead to the coexistence of a strictly sexual morph with a cyclic parthenogenetic morph. Our findings provide a novel hypothesis (positive density dependance and Allee effects) for the frequent coexistence of sexual and asexual plant parasites

Повний текст джерелаThe consequences of human-induced disturbances on wild populations is a stimulating topic raising fundamental as well as applied questions. The effects of urbanization on wild life have been initially studied at the community level. However, even if urbanization influences communities, the selective pressures occur first on populations and individuals. Consequently, it is also crucial to consider the ecological problems at the population level. The Blackbird Turdus merula has colonized urban landscapes in Europe since the middle of the 19th century and provides good opportunities to explore the influence of urbanization on population biology. The aim of this work was to compare urban and forest Blackbird populations in terms of different population characteristics (survival, reproductive success and dispersal) and selective contraints (parasites). Direct (i. E. Capture and census of individuals) and indirect methods (i. E. Genetic) were used in order to assess the dynamics of these populations

Повний текст джерелаUn objectif de ce travail était d'étudier la pathogénicité de deux groupes de parasites (tiques et Haemosporidae) au sein de populations de Merles noirs. Ces deux groupes de parasites se sont révélés associés aux indices de condition corporelle et de réponse immunitaire des individus. Cependant, l'étude d'une population urbaine ne nous a pas permis de confirmer un effet des Haemosporidae sur la survie et la dynamique de la population de Merles.
L'incidence du milieu de vie (structuration spatiale) sur le fonctionnement de la relation hôte-parasite a été également abordée. En effet, le Merle est une espèce ubiquiste. Nous avons montré que les populations de milieu urbanisé présentent des infections parasitaires plus faibles que celles vivant en milieu forestier. Ce résultat pourrait expliquer en partie les fortes densités de Merles en zones urbaines, même si d'autres interprétations restent bien sûr envisageables.
Enfin, divers travaux récents suggèrent le rôle des caroténoïdes comme lien entre l'immunité des mâles et l'intensité de leur signaux colorés. Cependant, ces études utilisent des mesures de l'immunité par challenge immunitaire pour « mimer » les infections parasitaires. Cette démarche a été récemment discutée car les challenges pourraient ne pas toujours refléter la résistance parasitaire. Nos résultats vont dans ce sens. De plus, nos travaux semblent montrer que le contexte social module la relation entre immunité et signaux colorés. Ceci pourrait remettre partiellement en cause l'idée selon laquelle les caroténoïdes constituent un mécanisme universel garant de l'honnêteté des signaux.

Повний текст джерелаProspections performed in Gabon, showed that 9 species of mistletoes parasitize many woody trees, among which rubber trees. From our study focussed on the biggest industrial rubber tree plantation of Mitzic, performed on more than 15 000 trees belonging to 7 different clones, it turned out that the percentage of parasitism ranges from 19 to 91% according to the clone. Phragmanthera capitata is by far the major species (about 95%). No real resistance to mistletoes was found for any of the 7 clones. However, a scale of susceptibility could be established, ranging from very susceptible clones like GT 1, AVROS 2037, PB 217 and PB 235 to less susceptible ones like PR 261, RRIM 600 and PB 260. No correlation could be established between the anatomy or tanin levels of bark from healthy trees, and the reaction of rubber trees to Loranthaceæ. On the other hand, a morphometric study showed that the less parasitized clones exhibited the most branched trees. Using several parameters, it turned out that parasitism has no significant effect on latex production and on physical properties of rubber. These results, discussed in relation with the biology of mistletoes, suggest that there is no point, for the moment, to eradicate mistletoes in gabonese rubber trees plantations

Повний текст джерелаThis document is dedicated to the dynamic modeling of host-parasite interactions. It is about two distant biological models, who are studied using standard epidemiological models built from dynamic compartmental models. The first contribution is the implementation of a 'micro-parasites' model to study the transmission of the protozoan parasite Trypanosoma cruzi, the etiological agent of American trypanosomiasis (or 'Chagas' disease), within a host community of synanthropic and domestic animals. The analysis of the mathematical model shows for the first time in this biological system a dilution effect associated with avian hosts, as well as the possibility of reducing the transmission to humans by modifying the composition of the domestic host communities. The second contribution deals with the dynamics of the "genomic parasites" that are the transposable elements. Using the analogies between genomics and ecology concepts proposed by the "Genome Ecology" approach, it was possible to adapt models developed for 'macro-parasites' to the dynamics of transposable elements of class 1, retro-transposons. The analysis of these models makes it possible toformulate hypotheses on the relative importance of the host demography, the distribution of the number of copies between individuals and the molecular mechanisms of silencing of these elements, on their persistence within the population of hosts reproducing asexually

Повний текст джерелаMy research examines the prevalence and distribution of the parasite Angiostrongylus cantonensis, also known as the rat lungworm, in Haiti. It is the leading cause of eosinophilic meningitis in humans worldwide. This parasite has a complex life cycle involving definitive hosts (rats) and intermediate hosts (snails and slugs). I documented the parasite's ecology and persistence two decades after its initial discovery in the country. Three objectives were set: synthesizing knowledge on the spatial and ecological dimensions of A. cantonensis’ niche, determining its presence and distribution in Haiti among rat and gastropod populations using molecular and morphological analyses, and identifying genetic similarities between Haitian strains and those from other regions of the world. We targeted two contrasting ecological contexts: the Artibonite Valley (rural environment) and the urban area of Port-au-Prince. Sampling occurred during and at the end of the rainy season due to the potential influence of hydrological seasonality on parasite prevalence. A systematic review using the PRISMA method synthesized existing knowledge on the parasite's ecological niche, focusing on abiotic and biotic factors affecting its dynamics. Seventy rats were captured:23 Rattus norvegicus and 47 Rattus rattus. Under a binocular loupe, we recovered adult worms from only five rats (7%, 5/70), but molecular detection revealed a prevalence of A. cantonensis in rat lungs of 31.4% (22/70), with the parasite detected in four of the eight sites, including Port-au-Prince. Parasite prevalence was not significantly related to predictive variables such as age, season, sex, and rat species. Only one COX1 haplotype, genotype II-G, was identified in Haiti, suggesting a widespread distribution similar to other regions. The qPCR technique AcanR3990 identified two positive samples of gastropod species: Subulina octona in Port-au-Prince and a Veronicellidae slug in the Artibonite, indicating the presence of the parasite found in rats at these locations. This is the first study on A. cantonensis in Haiti addressing both definitive and intermediate hosts. Molecular diagnostics by PCR reveal a higher prevalence than morphological identification, promising for the systematic study of potential host species contamination. Results indicate that endemicity of the parasite may primarily be linked to two gastropod species: the land snail S. octona and Veronicellidae slugs, as well as R. rattus and R. norvegicus rats, highlighting significant health risks for local populations
