Full textParmi les differents genes rapporteurs testes (-galactosidase, -glucuronidase et luciferase), seul le gene de la luciferase semble utilisable. La recherche d'un promoteur homologue a ete entreprise. L'adnc de l'actine non musculaire de b. Glabrata a ete clone et utilise comme sonde pour isoler son promoteur. Aucun element transposable n'ayant encore ete identifie dans le genome du gasteropode, nous avons teste, sans succes, la mobilite de 2 transposons d'insectes (hobo de d. Melanogaster et hermes de m. Domestica) dans les cellules bge. Par une strategie pcr et a l'aide d'amorces derivees du transposon mariner, une sequence presentant une faible homologie avec les sequences de mariner de d. Tigrina (planaire) et c. Elegans (nematode) a ete isolee qui correspond probablement a un vestige de transposase. Sur la base de ces resultats, la caracterisation d'un element transposable chez b. Glabrata est envisageable

Full textIn light of the significant increase in the emergence and re-emergence of infectious diseases worldwide, it is crucial to understand the factors involved in these events. Among these factors, food resources and the microbiome appear central in the tripartite relationship composed of the host, the pathogens it transmits, and the environment. Thus, the objective of this thesis was to identify the links between biotic and abiotic environmental factors, the microbiome, and vector competence in mollusks and arthropods that vector zoonotic diseases. This research has enhanced our understanding of the bacterial communities within the microbiome of natural populations of Bulinus truncatus and Galba truncatula, and has studied the influence of environmental factors and host genetics on these communities. It has also evaluated the link between plant-based food resources and the vector competence of laboratory populations of Aedes albopictus. These studies provide new and relevant insights into how interactions between the environment, the microbiome, and host vector competence can influence the transmission dynamics of infectious diseases, offering perspectives for managing infectious diseases and identifying high-risk areas for emergence

Full textInfectious diseases have shaped the history of the human species. Nowadays, the emergence of new pathogens threatens public health. Understanding the interaction between pathogen ecology and human behaviour can help understanding the dynamics observed in human populations. In this thesis, two main axes were studied: the epidemic dynamics of emerging infectious diseases (EID's) in human populations and the impact of human behaviour on the control of infectious diseases. The epidemic dynamics of emerging pathogens is poorly understood because it is often studied without taking into account the effect of their characteristics, namely their persistence in a reservoir population and their ability to emerge in a broad range of species. For the first time, we modeled the dynamics of EID's and highlighted that transmission from both the reservoir and intermediate populations are critically important to consider in order to understand the many and unpredictable outbreaks that can be observed. Thereafter, the impact of human behaviour on infectious diseases control was studied by considering two aspects, vaccination decision-making and cultural practices. We show that consideration of cognitive biases related to vaccination decision-making and the interaction between behaviour and epidemiology can lead to the fluctuations observed in vaccination coverage. Finally, the study of cultural practices has shown that, although often assumed to favour the spread of pathogens in a population, certain practices can limit disease transmission. The results taken together suggest that an ecological approach is key for predicting the dynamics underpinning the emergence and re-emergence of infectious diseases and adapt control strategies

Full textToxoplasma gondii is a protozoan parasite that belongs to the Apicomplexa phylum. It causes toxoplasmosis, a generally benign disease that can turn severe especially in case of immunodeficiency as a consequence of the reaction of parasites that persist in deep tissues. T. Gondii is an obligate intracellular parasite that manipulates the host signaling pathways to build a niche where to grow and persit. To this end, the parasite secretes several proteins, mostly kinases so far, that inhibit innate cellular defense and controls the immune response. We have identified a kinase counteracting protein, namely a ser/thr phosphatase type 2C (TgPP2C). This work shows that parasites modified at the endogenous locus secrete a fusion TgPP2C-HA into the host cell cytoplasm. In order to identify putative TgPP2C partners and substrates, a Yeast Two Hybrid screen has been carried out and has identified FM08 as partner candidate. The second part of this thesis aims at characterizing the FM08 protein for which nothing was known a part from its mention within a list of putative regulators of MAPK pathway. We discover that FM08 binds indeed to TgPP2C but is chiefly is a selective partner of intermediate filaments in epithelial cells. The partnership is quite sustained along the filaments but also when these reorganize into particles as during mitosis or upon oxidative stress. We also point a larger complex including the p38 as a bonafidae partner of FM08. Our current investigation assesses whether FM08 is a substrate of p38 and how it could be involved in controlling the cytokeratin-mediated cell response to stress including during infection in order to preserve cell and tissue integrity
