The role of mobile genetic elements in adaptation of the microbiota to the dynamic human gut ecosystem

Phylosymbiosis between primates and their gut mycobiomes. Top left: Sample-wise mycobiome composition for each host species. The most abundant fungal genera and classes (Sordariomycetes, Saccharomycetes, and Dothiomycetes) are shown in colored bars, where the lightest color in the gradient designates the sum of all other genera in that fungal class. Light gray shows all other less abundant fungal genera. Top right: Primate phylogeny (left; scale bar shows MYA) and fungal Bray–Curtis beta diversity relationships based on 99% OTUs and aggregated by host species (right; shown with bootstrap support for branch placement and scale bar for relative branch lengths). Bottom: Cophylogenetic fungi with time-calibrated sequence divergences match hominid divergence times. Nucleotide sequence divergence of cophylogenetic fungi was calibrated to the Homo-Pan split (6 Ma), which was then used to estimate the Homo/Pan-G. gorilla split (7.1–9.2 Ma), shown with fungal icons. Estimated speciation times fall within the expected 7.1–9.2 Ma (dark orange) or 6–10 Ma (light orange)

I am so proud to be part of this work, that we initiated Fernando de la Cruz and I, when he was on sabbatical in my lab in 2009... it took so much time for this achievement, 1000 thanks to Raúl Fernández-López! this brought me back to my PhD on cyanobacteria genetics. www.pnas.org/doi/10.1073/...

Phages with a broad host range are common across ecosystems - Nature Microbiology Proximity-ligation-based sequencing from 111 samples and 5 environments reveals that a substantial proportion of phages infect multiple species.

You like phages ? In this publication, we use metaHiC and our new version of the MetaTOR pipeline to challenge the traditional view of phages with a narrow host range.

Exclusion systems preserve host cell homeostasis and fitness, ensuring successful dissemination of conjugative plasmids and associated resistance genes Abstract. Plasmid conjugation is a major driver of antibiotic resistance dissemination in bacteria. In addition to genes required for transfer and maintena

Exclusion systems, far from slowing down plasmid spread, are in fact essential to preserve host cell viability and thereby ensure the successful dissemination of conjugative plasmids and antibiotic resistance genes.

Climate change is projected to worsen #AMR in LMICs, due to poor healthcare infrastructure and environmental vulnerability. Development strategies (improving sanitation, healthcare access, immunization) are more effective combating AMR than reducing antibiotic use.
