Sorry for the delayed post, WordPress was playing some mean tricks on me today and there were no treats! Good morning all and happy spooky season! It’s been a moment since I’ve written a post and I write to you now as a freshly (pepper)minted PhD! I’m feeling gourd and can’t wait to pumpkin spice things up with some fangtastic papers.

Some of the highlights include a paper by McAlpine et al. examining interkingdom relationships between bacteria and fungi. Specifically, they found that the gut commensal species Lactobacillus can produce a small molecule that blocks filamentous growth of the opportunistic pathogen Candida albicans. Another interesting paper comes from Michael Adams lab at the University of Georgia, Athens which showed that members of the gut microbiota have the capacity to assimilate the metal tungsten which, in turn, allows these microbes to oxidize a broad range of aldehydes in the gut. Additionally, a paper by Plummer et al. looked at the vaginal microbiota of women who have recurrent bacterial vaginosis as well as the penile microbiota of their partners, and found that when males also underwent antibiotic treatment it led to a decrease in bacterial vaginosis in their female partners.

Hope you enjoy reading these fa-boo-lous papers and may you eat, drink, and be scary this Halloween!

Bonjour from Paris, France ! Today’s digest contains a selection of really interesting preprints and published studies. In their review, Heilbronner and collaborators explore the role of bacteriocins, small antibacterial molecules produced by many commensal bacteria in human-associated microbiomes. The role of the bacteriocins in the human microbiome is of particular importance since they could be leveraged to specifically target colonizing pathogens while sparing mutualistic patners.

If you are interested in exploring new bioinformatic methods, I recommend taking a look at the study from Cheng and collaborators, who applied a novel iterative random forest approach to explore marine microbiome during algal blooms. They show how this model allow to identify conditions that are important causal factors of algal bloom dynamics.

Today’s non-microbiology pick is an opinion piece reflecting on the possible methods to develop the field of computational biology, ensure proper training and career development in this discipline and allow a greater collaboration between domain biologist and data scientists in multidisciplinary teams.

Have a great Tuesday!
