Abstract Industrial production of the unicellular green alga Haematococcus lacustris is compromised by outbreaks fungal pathogen Paraphysoderma sedebokerense (Blastocladiomycota). Here, using axenic algal and cultures antibiotic treatments, we show that bacterial microbiota H. necessary for infection P. its modulation affects outcome interaction. We combined metagenomics laboratory cultivation to investigate diversity associated three species monitor change upon infection. unveil types...
Abstract With more than 12 million inhabitants, the Greater Paris offers a “natural laboratory” to explore effects of eutrophication on freshwater lake’s microbiomes within relative restricted area (~ 70 km radius). Here, 4-months survey was carried out during summertime monitor planktonic microbial communities nine lakes located around (Île-de-France, France) comparable morphologies, yet distinct trophic statuses from mesotrophic hypereutrophic. By thus minimizing confounding factors, we...
Untargeted metabolomics is a non-a priori analysis of biomolecules that characterizes the metabolome variations induced by short- and long-term exposures to stressors. Even if metabolite annotation remains lacunar due database gaps, global metabolomic fingerprint allows for trend analyses dose-response curves hundreds cellular metabolites. Analysis dose/time-response curve trends (biphasic or monotonic) untargeted features would thus allow use all chemical signals obtained in order determine...
Aghien lagoon (Ivory Coast) is a eutrophic freshwater that harbors high biomasses of phytoplankton. Despite Increasing interest in fish gut microbiomes diversity and functions, little data currently available regarding wild species from tropical west African lakes. Here, gut-associated bacterial communities are investigated four consumed by locale populations, namely the Cichlidae

Knowledge regarding its associated microbiota on the other hand still scarce limited to adults, despite relevance of microbiome host's biology. This study provides first insights into establishment bacterial during early stages laboratory-reared medaka using 16S-rRNA-sequencing-based approach. Major shifts in community compositions are observed,...
Abstract Untargeted metabolomics is a non- priori analysis of biomolecules that characterizes the metabolome variations induced by short- and long-term exposures to stressors. Even if metabolite annotation remains lacunar due database gaps, global metabolomic fingerprint allows for trend analyses dose-response curves hundreds cellular metabolites. The combination untargeted features benchmark-dose (BMD) calculations then makes it possible determine concentration range inducing defense...
The prawn Palaemon serratus exhibits a large distribution (occurring along the Northeastern Atlantic coast to Mediterranean), and has thus been found suitable as model organism valuable for various ecotoxicological studies. However, little is still known about potential input of its metabolome particularly concerning molecular sexual dimorphism observable in different tissues this organism. In an point view, inter-sex inter-organ differences metabolomes may introduce analytical bias impact...
Cette étude est la reprise d'un travail sur le clergé du Maine au xixe siècle laissé inachevé par Pierre Foucault décédé en septembre 2006. Il s'agit d'une comparaison entre présentation de vocation faite les évêques et clergé, enseignements tirés peu plus 170 récits vocation, l'âge auquel se manifeste rôle des familles dans son éclosion, sa découverte réalisation. Les (qui rejoignent évêques) mettent l'accent non seulement discernement mais aussi réalisation, soutien intellectuel financier...
Abstract With more than 12 million inhabitants, the Greater Paris offers a “natural laboratory” to explore effects of eutrophication on freshwater lakes within relatively restricted area. Here, four-month time-series was carried out during summertime monitor planktonic microbial communities nine located ∼70 km radius around (Île-de-France, France) comparable morphologies, yet distinct trophic statuses (mesotrophic hypereutrophic). The contribution status and intra-summer variations were...
Abstract Massive sequencing of the 16S rRNA gene has become a standard first step to describe and compare microbial communities from various samples. Parallel analysis high numbers samples makes it relevant statistical testing influence natural or experimental factors variables. However, these descriptions fail document changes in community ecosystem functioning. Non-targeted metabolomics are suitable tool bridge this gap, yet extractions protocols different. In study, prokaryotic...
The zebra mussel, Dreissena polymorpha, is extensively used as a sentinel species for biosurveys of environmental contaminants in freshwater ecosystems and ecotoxicological studies. However, its metabolome remains poorly understood, particularly light the potential molecular sexual dimorphism between different tissues. From an point view, inter-sex inter-organ differences suggest variability responsiveness, which can influence analysis interpretation data, case where males females would be...

Summary The gut microbiota of 2-3 month-old infants is associated with later pre-allergic signs, while the at time allergic manifestation not. We hypothesized that infant and immune system are primed shortly after birth, this influenced by maternal transfer humoral immunity. investigated association between outcomes composition immunity to 2 months, years-of-age. Meconium clustered into three groups dominated Escherichia , Enterococcus mixed genera, respectively. cluster was protection...
Quelle image les Sarthois se font-ils des pays qui s’étendent de l’Inde jusqu’aux extrémités orientales du continent asiatique dans la période 1860-1914 ? Font-ils entrer leur vie réalités asiatiques L’étude presse locale permettra répondre à ces deux questions. Le le plus cité est Chine, suivie l’Indochine ; Japon et sont très en retrait. L’image ambivalente : d’une part cocagne regorgent richesses toutes sortes, l’autre terres catastrophes mort. Ce aussi sociétés impitoyables évoqués...

Abstract Blooms of toxic cyanobacteria are a common stress encountered by aquatic fauna. Evidence indicates that long-lasting blooms affect fauna-associated microbiota. Because their multiple roles, host-associated microbes nowadays considered relevant to ecotoxicology, yet the respective timing microbiota versus functional changes in holobionts response needs be clarified. The gut and holobiont’s metabolome exposure dense culture Microcystis aeruginosa was investigated as...
