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 !

Good morning from Northern Germany! It is almost Xmas. Today’s microbiome digest is rather long and comprises some interesting findings about c-section and the gut microbiome in early life, human breast milk, chronic pain, antimicrobial resistance, imbalance of the gut microbiome in relation to Parkinon’s disease and COVID19, diet, honey bees (two pre-prints), roundup, and last but not least some bioinformatic papers. Additionally, we select some interesting reviews. Of specific interest is a study about showing reveals poor correlations in microbial taxonomic abundance between humans and mice after gnotobiotic transfer.
