Joyeuses fêtes from Paris, France ! In today’s digest, you will find great papers looking at various animal and plant microbiomes. In particular, I recommend taking some time to look at a preprint from Brealey and collaborators exploring the impact of human antibiotic use on oral microbiome in wild animals. The authors used shotgun metagenomics to determine the abundance and diversity of antimicrobial resistance genes in the oral microbiome of brown bears from Swedish museum specimens. Importantly, they show a significant increase in antimicrobial resistance genes in correlation with modern human antibiotics use, showing an impact even on wildlife of our antibiotic consumption.

Today’s non-microbiology pick takes a look back at the history of bioinformatics through the data analysis and visualization of papers published between 1998 and 2019. In addition of reading this very interesting paper, you can take a look at the data collected through interactive visualizations available at http://bioinfo.dcc.ufmg.br/history !

Hello from the Sonoran Desert! In today’s digest, you’ll find great papers, in particular in soil and water microbiology but also in bioinformatics! As an example, Mara and collaborators are exploring the viruses found in the oxygen-deficient water column of the Cariaco basin. Interestingly, a large diversity of viral Auxilliary Metabolic Genes (AMGs) were found and give new insights in how phages may interact with their bacterial hosts in this understudied ecosystem.

In the bioinformatics section, I recommend anyone interested in phage metagenomics to take a look at the paper from Ren and collaborators. The authors have developed a reference-free and alignment-free deep learning tool, called DeepVirFinder, allowing the retrieval of viral sequences in metagenomes.

Today’s non-microbiology digest is a paper announcing the last update of the Genome Online Database (GOLD), a manually curated collection of genome projects and their metadata from around the world, which now contains more than a million entries! Great news for bioinformaticians!

Happy Monday morning from San Francisco, California! Hope everyone had a restful weekend. For those who aren’t quite ready for the working week, how about easing in to things with a warm beverage and some great microbiome reads?

Today’s digest includes two papers that blew my mind. The first is a paper by van Tatenhove-Pel et al. which looks at how cell-to-cell distance in 3D space impacts the metabolic interactions between bacteria. The second, by Nowosad et al., examines the role of the gut microbiota on B cell selection and antibody affinity maturation in gut-associated germinal centers. Other fascinating papers include: a pilot study profiling the gut microbiomes of South Africans in an urban cohort and a transitioning rural cohort which was designed collaboratively with community leaders (Oduaran et al.); a review paper about using brachyuran crabs as a model for studying how animal-microbiome symbioses evolve when aquatic organisms transition to land (Cannicci et al.); and a paper that used shotgun metagenomics to identify current and historical microbiomes in lake sediment which could help our understanding of how humans impact lake ecosystems over time (Garner et al.). Happy reading, y’all!
