Hello from the Sonoran Desert! In today’s digest, you’ll find two very interesting reviews! Stagaman and collaborators come back on years of Zebra-fish gut microbiome research and explore the insights gleaned from this awesome model animal. On the other hand, François and Pybus review our understanding of avian viromes in both wild and domesticated bird populations, highlighting the current limitations and pitfalls in this research area.

But today’s digest also contains very interesting research papers! Gulino and collaborators are exploring viromes in New York city wastewater systems. This paper is particularly interesting as bacteriophages are typically left out from urban environments microbiomes studies, despite their abundance and importance in ecosystems.

Finally, today’s non-microbiology pick is a review that comes back on how information theory, developped by Claude Shannon in the late 40s, have been used in computational biology. This paper is particularly interesting for readers wanting to learn more about the basics of information theory and how it is applied today in bioinformatics.

Have a great Sunday!

Hello and welcome to Wednesday’s Digest! Today’s selection includes two separate but complementary papers from Cell Host & Microbe. The first, from Brett Finlay’s lab, investigates what drives the loss of Immunoglobulin A recognition by beneficial bacteria in the gut of undernourished children. The second, from Jeffrey Gordon’s lab, examines the impact of prebiotic and microbial interventions on oral vaccination responses in a mouse model of childhood undernutrition. These papers both highlight the important relationship between nutrition, the microbiota, and host mucosal immunity.

There are also a few fungi-focused papers today as well as some interesting animal microbiome research. Tan et al. compare the microbiome of pigs and their farmers and Andrade-Oliveira et al. found that antimicrobial resistance genes from a feline oral commensal can be transferred to a human-associated staphylococci. I also want to call attention to the techniques section, especially a paper by Song and Xie in which they used CRISPR/Cas9 to deplete host contamination in 16S rRNA gene amplicon samples.

Today’s Digest is heavy, so you might want to pace yourself. It’s hard to pick the highlights, but I’m biased towards fungal research, so first about a wake-up call to look at the fungi seriously. The insects might provide for remedy against antibiotic resistance and is the dust settled on the sparse fetal intestinal microbiota? Stay healthy and keep reading.
