Good morning everyone!

Today’s digest presents several antibiotic resistance papers, as well as hospital ICU microbiome study, a microbial nomenculture paper, bunch of human microbiome papers (both gut and vaginal), as well as two computational platforms for analyzing microbial data.

In a more personal note– recently, my PhD research (at ARO and The Hebrew U, Israel) resulted in two manuscripts dealing with the exciting world of bacterial secondary metabolites. The first one is a review paper where we present state-of-the-art tools and methodologies to study and identify novel secondary metabolites gene clusters within the widely diverse soil and root bacterial communities. We present a conceptual pipeline for an efficient use of these culture-based and culture-independent platforms to identify novel antimicrobials-producing gene clusters in-vivo.

The second one (a bioRxiv pre-print) utilized some of these techniques to explore differences in secondary metabolites gene clusters between soil and roots bacterial communities, in terms of diversity, composition and taxonomy. We then took advantage of this data and deeply focused on root-enriched and abundant sequences (those that were associated with NRPS and PKS, mega-enzymes that produces two very important families of secondary metabolites- nonribosomal peptides and polyketides). Then, we used a unique culture-independent platform (eSNaPD, from Sean Brady lab @ Rockefeller U, NY) and were able to actually recover 5 clones (~40Kb in length) that harbored five novel gene clusters. At least one of these probably encode for an antifungal metabolites (derived from Actinobacteria). This piepline/platform is applicable for other uses of course, depending on your research question and the functions you’re intrested in. I’ll be happy for any feedback regarding the bioRxiv MS (either directly there or via my tweeter).

Happy Wednesday, y’all! Before we get to today’s papers, I wanted to let everyone know about a webinar happening on June 3rd at 12:00 PM E.T. called “Unraveling the link between the gut microbiome, human health, and disease.” Tomoya Yamashita, M.D., Ph.D. from Kobe University Graduate School of Medicine and Meredith Hullar, Ph.D. from the Fred Hutchinson Cancer Research Center will both be speaking. If you’re interested you can register here.

Now onto the highlights! We have some super interesting research to share with you today including an examination of the efficacy of transplanting the human gut microbiota into mice and its impact on studying immunological responses; evidence that early-life intestinal colonizers may influence brain development; and a new tool, pepFUNK, which uses a peptide-centric approach to identify KEGG pathways in metaproteomic datasets. Enjoy!
