Summary Microbiota can have positive and negative effects on hosts depending the environmental conditions. Therefore, it is important to decipher host–microbiota–environment interactions, especially under natural conditions exerting (a)biotic stress. Here, we assess relative importance of microbiota in different tissues Pacific oyster for its successful establishment a new environment. We transplanted oysters from Southern N orthern W adden S ea controlled resident by administering...
Transgenerational effects can buffer populations against environmental change, yet little is known about underlying mechanisms, their persistence or the influence of cue timing. We investigated mitochondrial respiratory capacity (MRC) and gene expression marine sticklebacks that experienced acute developmental acclimation to simulated ocean warming (21°C) across three generations. Previous work showed grandmothers 21°C led lower (optimized) offspring MRCs. Here, mothers higher, but more...
Unveiling the factors and processes that shape dynamics of host associated microbial communities (microbiota) under natural conditions is an important part understanding predicting organism's response to a changing environment. The microbiota shaped by (i.e., genetic) as well biotic abiotic Studying variation community composition in multiple genetic backgrounds across spatial temporal scales represents means untangle this complex interplay. Here, we combined spatially-stratified with...
Protozoa have long been considered undesirable residents of the human gut, but recent findings suggest that some them may positively affect gut ecosystem. To better understand role and ecological dynamics these commensal potentially beneficial protozoan symbionts, we need efficient methods to detect them, as well accurate estimates their prevalence across populations. Metagenomics provides such an opportunity, allowing simultaneous detection multiple symbionts in a single analytical...
Human gut microbial communities are mainly composed of bacteria, but also include fungi, viruses, archaea, and protozoa, whose role in the ecosystem has only recently begun to be recognized. For example, humans colonized by Blastocystis (a protozoan with controversial pathogenicity) host a more diverse bacterial microbiota than individuals not carrying it, suggesting that its presence may beneficial for host. In parallel, non-pathogenic Entamoeba spp. been associated an increased diversity...
Abstract Urban populations from highly industrialized countries are characterized by a lower gut bacterial diversity as well changes in composition compared to rural less countries. To unveil the mechanisms and factors leading this loss, it is necessary identify associated with urbanization-induced shifts at smaller geographical scale, especially do so, we investigated potential associations between variety of dietary, medical, parasitological socio-cultural saliva microbiomes 147...
Abstract Background The impact of the microbiota on host fitness has so far mainly been demonstrated for bacterial microbiome. We know much less about host-associated protist and viral communities, largely due to technical issues. However, all microorganisms within a microbiome potentially interact with each other as well environment, therefore likely affecting health. Results set out explore how environmental factors shape composition diversity bacterial, microbial communities in Pacific...
Host-parasite interaction can result in a strong alteration of the host-associated microbiota. This dysbiosis affect fitness host; modify pathogen and outcome diseases. Biomphalaria glabrata is snail intermediate host trematode Schistosoma mansoni, agent human schistosomiasis, causing hundreds thousands deaths every year. Here, we present first study bacterial microbiota response to infection. We examined interplay between B. glabrata, S. mansoni Snails were infected composition was analysed...
Abstract On theoretical grounds, antagonistic co‐evolution between hosts and their parasites should be a widespread phenomenon but only received little empirical support so far. Consequently, the underlying molecular mechanisms evolutionary steps remain elusive, especially in nonmodel systems. Here, we utilized natural history of invasive to document underpinnings co‐evolutionary trajectories. We applied dual‐species transcriptomics approach experimental cross‐infections blue mussel Mytilus...
Background: The choice of efficient antipsychotic therapy for schizophrenia relies on a time-consuming trial-and-error approach, whereas the social and economic burdens disease call faster alternatives. Material & methods: In search predictive biomarkers response, blood methylomes 28 patients were analyzed before 4 weeks into risperidone therapy. Results: Several CpGs exhibiting response-specific temporal dynamics identified in otherwise temporally stable noticeable global response-related...
Summary Host-associated microbiota cari affect the fitness of its host i η a number ways, including modification host-parasite interactions and thus outcome disease. Biomphalaria glabrata is vector snail trematode Schistosoma mansoni, agent human schistosomiasis, causing hundreds thousands deaths every year. Here, we present first study bacterial in response to infection. To examine interplay between B. glabrata, S. mansoni microbiota, snails were infected composition was analysed by massive...
Upon colonizing new habitats, invasive species face a series of selection pressures as result changing abiotic conditions and novel biotic interactions with native species. These can be accommodated by different mechanisms that act on levels across time scales: 1) By transcriptomic profiles, react plasticity within individual physiological limitations. 2) Invasive populations adapt fixing beneficial genetic variants in response to the newly encountered pressures. Here, we compare genomic...
