Benchmarking informatics approaches for virus discovery: caution is needed when combining in silico identification methods

Understanding the ecological impacts of viruses on natural and engineered ecosystems relies on the accurate identification of viral sequences from community sequencing data. To maximize viral recovery from metagenomes, researchers frequently combine viral ...

Meta-omics-aided isolation of an elusive anaerobic arsenic-methylating soil bacterium

Rizlan Bernier-Latmani, Karin Lederballe Meibom, Karen Elda Viacava Romo, Nicolas Louis Maurice Jacquemin, Matthew Charles Reid, Jiangtao Qiao

Soil microbiomes harbor unparalleled functional and phylogenetic diversity and are sources of novel metabolisms. However, extracting isolates with a targeted function from complex microbiomes is not straightforward, particularly if the associated phenotype ...

Energy efficiency and biological interactions define the core microbiome of deep oligotrophic groundwater

Rizlan Bernier-Latmani, Emma Bell

While oligotrophic deep groundwaters host active microbes attuned to the low-end of the bioenergetics spectrum, the ecological constraints on microbial niches in these ecosystems and their consequences for microbiome convergence are unknown. Here, we provi ...

Obesity-associated deficits in inhibitory control are phenocopied to mice through gut microbiota changes in one-carbon and aromatic amino acids metabolic pathways

Xavier Fernandez-Real Girona

Background Inhibitory control (IC) is critical to keep long-term goals in everyday life. Bidirectional relationships between IC deficits and obesity are behind unhealthy eating and physical exercise habits. ...

Biogeography of microbial bile acid transformations along the murine gut

Rizlan Bernier-Latmani, Laure Menin, Solenne Anne Marie Marion, Lyne Desharnais

Bile acids, which are synthesized from cholesterol by the liver, are chemically transformed along the intestinal tract by the gut microbiota, and the products of these transformations signal through host receptors, affecting overall host health. These tran ...

Infection with a small intestinal helminth, Heligmosomoides polygyrus bakeri, consistently alters microbial communities throughout the murine small and large intestine

Nicola Harris, Benjamin John Marsland, Mario Michael Zaiss, Alexis Rapin, Luc Xavier Marie Lebon, Audrey Geneviève Chuat

Increasing evidence suggests that intestinal helminth infection can alter intestinal microbial communities with important impacts on the mammalian host. However, all of the studies to date utilize different techniques to study the microbiome and access dif ...

Biogeography and biochemistry of bile acid 7-dehydroxylation in the mammalian gut

Solenne Anne Marie Marion

Bile acids (BAs) are small molecules synthesized by the host and chemically modified by the microorganisms inhabiting the intestinal tract. The microbial transformation of BAs in the gut is critical to BA-mediated signaling as it modifies their amount and ...

Microbiota Analysis Using an Illumina MiSeq Platform to Sequence 16S rRNA Genes

Nicola Harris, Alexis Rapin, Benjamin John Marsland, Céline Pattaroni

The microbiota have been shown to play an important role in diverse biological processes including immunity, metabolism, and digestion. Assessing the exact composition of the microbiota has proven challenging due to the often unknown growth specificities o ...

Systems Biology Approaches for Inflammatory Bowel Disease: Emphasis on Gut Microbial Metabolism

Martin Kussmann, Sofia Moco

Although the prevalence of main idiopathic forms of inflammatory bowel disease (IBD) has risen considerably over the last decades, their clinical features do not allow accurate prediction of prognosis, likelihood of disease progression, or response to spec ...
