Abstract:
Phytogeographical analysis of Central African forests: the Ngovayang massif (Cameroon) <b>Background and aims</b> – The Ngovayang massif, in southern Cameroon, is part of a group of small hills along the Atlantic coast of the Gulf of Guinea. This area is known for its floristic richness and its high level of endemism. We conducted a phytogeographical analysis of this massif and evaluated its floristic affinities with other forested sites in Central Africa. <b>Methods</b> – Phytogeographical analysis was based on a comparison of lists of tree species with dbh ≥ 10 cm, inventoried in 1-ha perman

Le SARS-CoV-2 est un virus de la famille des Coronaviridae, genre Betacoronavirus qui aurait pour origine un virus proche provenant d'une espèce de chauve-souris. Son émergence en Chine fin 2019 ainsi que l'apparition de nombreux variants ont donné lieu à la plus grande pandémie virale du XXIème siècle. L'infection va engendrer la maladie COVID-19 qui est caractérisée par des symptômes respiratoires pouvant être de légers à sévères avec une pneumonie parfois fatale. La réponse immunitaire innée est la première ligne de défense contre une infection virale et permet la synthèse d'interférons (IF

Abstract:
Le genre Ectocarpus Lyngbye (Ectocarpales, Phaeophyceae) regroupe des algues marines filamenteuses caractérisées par un cycle haploïde-diploïde. L'objectif de la thèse était de délimiter les espèces et d'étudier la spéciation dans ce genre. Nous avons commencé par clarifier le nombre d'espèces cryptiques en utilisant deux loci indépendants et une approche intégrative associant une analyse de détection de " barcode gap " avec des reconstructions phylogénétiques. Nos résultats montrent l'existence d'au moins 15 espèces qui se répartissent en un groupe monophylétique composé d'E. crouaniorum (Ecr

Abstract:
Anaplasma phagocytophilum est une alpha-protéobactérie à multiplication intracellulaire stricte transmise par les tiques du genre Ixodes sp. Responsable notamment des anaplasmoses granulocytaires bovine et humaine, elle peut également infecter de nombreux mammifères, tels les ruminants sauvages ou les rongeurs. En Europe, plusieurs cycles, encore mal connus, semblent coexister et impliquer des hôtes (réservoirs et victimes) différents. Cela semble être en particulier le cas pour les souches bovines et humaines, conduisant à supposer que les souches bovines ne seraient pas zoonotiques. Du fait

Abstract:
Nos études ont pour objectif d'évaluer l'impact de l'équilibre fonctionnel entre les protéines Hémagglutinine (HA) et Neuraminidase (NA) de virus influenza A sur la fusogénicité, le tropisme cellulaire et la pathogénicité, afin de mieux comprendre le franchissement de la barrière d'espèce et l'adaptation des virus influenza A. Nous avons donc développé deux tests phénotypiques : un test de fusion cellule-cellule et un test d'infectivité. Deux paramètres ont été abordés au cours de ma thèse : (i) le rôle potentiel de la NA dans les étapes précoces du cycle viral, et (ii) l'impact d'une délétion
