Happy Thursday from San Francisco! Today’s Microbiome Digest includes: a paper by Marbouty et al. in which a large number of phages and their interacting bacteria were identified in the healthy human gut; a thorough examination by Zhu et al. of the composition and metabolic potential of cave-dwelling bacteria, including sequencing of 14 new bacterial species; and a study by Mu et al. which found that the maternally-derived microbe Lactobacillus reuteri promotes immunoglobulin A production in the neonatal gut.

There is also a study by Serrano-Villar et al. which examined the use of fecal microbiota transplantation (FMTs) in HIV patients. The authors observed that FMT led to engraftment of two bacterial families–Lachnospiraceae and Ruminococcaceae–typically depleted in HIV-infected subjects and decreased levels of a plasma biomarker of intestinal permeability. While the findings are interesting, I remain skeptical of the appropriateness of FMTs in this context. Instead of an FMT–which requires donors and screening of their stool to ensure quality and safety–why not use a probiotic cocktail of Lachnospiraceae and Ruminococcaceae family members and perhaps include prebiotic factors to try to promote engraftment?

Additionally, there is a great article by Ras et al. discussing the results of a pilot study that successfully implemented microbiome-related bioinformatics courses across 11 African countries.

Hyvää Päivää from Helsinki, Finland ! Today’s digest contains quite a lot of different topics. If you are interested in gut microbiomes, I recomment taking a look at the preprint by Weiss and collaborator. In this study, they explore bacteria-bacteria interactions, bacterial growth and metabolic interactions in a synthetic bacterial community: the Oligo-Mouse-Microbiota, which is increasingly used as model system in gut microbiome research.

Additionally, anyone interested in microbiome-based forensic tools should read the study from Sang You and collaborators.  They compared the composition of microbial communities in blood spot surfaces placed in different environments sampled across seasons and time points, in order to evaluate the environmental factors leading to variation in these microbial communities.

Today’s non-microbiology pick is a fascinating study looking at the prevalence of COVID-19 related misinformation among the Yemeni population and its association with vaccine acceptance and perceptions. From this study, the authors recommend the deployment of awareness campaigns to decrease misinformation before initiating any mass vaccination in Yemen.

Have a great Weekend!
