Many environmental factors are known to disrupt the microbial balance of the microbiota and thus affecting honeybee health. T...
Traces of bacterial DNA and volatile compounds as first factors of traceability pertaining to salt from regional marshes in the Atlantic Ocean.
Salt has always been exploited in living memory. It has known its heyday at several occasions throughout history, particularly during the period of the French Gabelle, and therefore came to be seen as a precious white metal both sought after and expensive. Yet, nowadays, although it has been conside...
The different microbiota of the Holobionte Grand Coregonus clupeaformis (Coregonus clupeaformis) in a specialty context
Animals have evolved with their microbiota. However, little is known about the role of bacteria over the course of this evolution. These last few years, it has been shown that the microbiota influences speciation by controlling the pre-zygotic and post-zygotic reproductive isolation. The main goal o...

Description of the enzymatic systems from the human ileal microbiota dedicated to fibre degradation and enzyme exploration of the fecal microbiota from an obese individual : a functional metagenomic approach looking for unrevealed glycoside hydrolases
Among the crucial functions of the intestinal microbiota, extracting energy from food such as dietary fibres is of major importance. Facing the huge diversity of incoming complex carbohydrates, the fibrolytic bacteria synthesize a set of diversified Carbohydrate-Active Enzymes (CAZymes) including Gl...
Microbiota ontogenesis in vivipare fish Brachyistius frenatus: vertical transmission of pioneering microbial symbites?
In Mammals microbial recruitment starts in utero, something that had not been shown in any other Vertebrate class. The main goal of this project was to test whether this type of recruitment happens in a non-mammalian Vertebrate. We tested in the viviparous fish Brachyistius frenatus the hypothesis u...
Bacterial communities associated with a Mediterranean holobiont, the red gorgonian Paramuricea clavata : diversity, stability and specificity
Coralligenous communities dominated by gorgonian species have been severely affected by diseases and mass mortality events linked to the current warming trends reported for the Mediterranean Sea. The characterization of the natural microbial compartment of this temperate gorgonian species becomes a...
Contribution of culturomics in the elucidation of bacterial metagenomics Dark Matter
The role of human microbiota in pathology and health has been proven by numerous studies that have shown its major involvement. The tool of choice for the study of the microbiota is metagenomics, which has made it possible to highlight the diversity of bacteria, but also that much of this diversity...
Influence of breeding sites on the bacterial microbiota, the vector competence and survival of the Aedes aegypti mosquito
The Aedes aegypti mosquito is the main vector for dengue (DENV) and Zika (ZIKV). It becomes urgent to develop new tools to reduce the transmission of these viruses to humans by the mosquito. One promising area concerns bacteria associated with mosquito vectors: the bacterial microbiota. The natural...
Identification of bacterial endophytes of interest for coffee crop in Vietnam
Vietnam is the second largest coffee producer worldwide. It is also the leading producer and exporter of Robusta coffee (Coffea canephora). Over the past decades, Vietnamese coffee cultivation has greatly intensified at the expense of the environment. In addition to deforestation, land degradation a...
Bacterial-fungal interactions within the endomicrobiota of brown algae : implication of quorum sensing in the metabolic crosstalk
Macroalgae host various microorganisms, collectively referred as the algal microbiota, which play an essential role in the development and health status of their host. In this work, we explored the bacterial and fungal microbiota of brown algae, as well as the impact of bacterial fungal interactions...
Exploring the human gut microbiota enzymes involved in the complex carbohydrate degradation
The bacterial communities that inhabit our gut ensure their growth and survival by extracting their carbon source from the food that transits through the intestines. The complex carbohydrates included in the human diet are almost exclusively degraded by the gut microbiota using CAZymes. We built a m...
Development of innovative tools for the study of chronic infection
One of the major challenges in the management of diabetic foot wounds is to obtain information to anticipate the evolution of these infections. Currently, there are no sufficiently effective tools to distinguish a colonized wound to an infected wound. The proposed approach is based on the discrimina...
Caracterisation and role of microbiota in the interaction host/parasite between Planorbidae and trematode worm of Schistosoma genus, responsible agent of the bilharziose
Every living organism is faced, eventually, to microorganisms, whether they are bacteria, viruses, fungi or protists. Microbiota largo sensu represent all these microorganisms, living in a host a T time. It is considered, since years, as an integral compartment of its host. It can affect several hos...
Role of intestinal microbiota in waterfolws and host response
The intestinal microbiota plays a fundamental role in its host. Microbiota studies contribute to understand the different physiological mechanisms in the host. Then, following the ban on antibiotics as growth factors in animal feed, the use of probiotics has increased to improve zootechnical perform...
MAIT cells and riboflavin in host-microbiota interactions
Mucosal associated invariant T (MAIT) cells are an evolutionary conserved T cell subset, which recognize riboflavin precursor derivatives presented by MR1. Intestinal bacteria from the Bacteroidetes and Proteobacteria phyla can produce MAIT antigens, suggesting a direct interplay between MAIT cells...
Optimization of the curative and preventive use of cephalosporins in bacterial infections from PK/PD data, population pharmacokinetics, simulations and an analysis of the gut microbiota
Cephalosporins, discovered in the middle of the 20th century, belong to the beta-lactam class and act by inhibiting the synthesis of bacterial peptidoglycan. Many factors can affect their effectiveness but also their adverse effects. This thesis work articulated in 3 parts was interested in the phar...
