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.

Happy reading, y’all!
