My personal favorite review is by Berthoud et al. on gut-brain communication with focus on understanding functions of the vagus nerve. Others include – rumen microbiome, gut microbiota in neuronal feeding circuits, gut-brain axis in gastrointestinal cancer and a beautiful snapshot illustrating summary of microbiota effects on host physiology.

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.

January 24, 2021

Hyvää Päivää from Helsinki, Finland ! Today’s digest contains quite a lot of different topics. If you are interested in  early-life microbiome, I recommend taking a look at the paper from Mortensen and collaborators. To understand the role of the maternal vaginal microbiome’s in seeding their child and the importance of the delivery mode in early-life microbiome acquisition, they studied 665 mother–child dyads and modeled the transfer of the vaginal microbiota from mother to infants.

In today’s digest, you’ll also find a really interesting preprint from Abiriga and collaborators, looking at the microbiome of a groundwater aquifer contaminated by a municipal landfill while undergoing intrinsic bioremediation. This preprint is particularly notable because studies looking at the microbiome of contaminated aquifers are particularly rare, despite groundwater contaminations from landfills being a very common issue.

Today’s non-microbiology pick takes a look at the difficulty of detecting scientificly fraudulent images produced by Generative Adversarial Networks (GANs). They demonstrate that this deep-learning method can generate realistic western blot images that are indistinguishable from real western blots. In conclusion, the authors argues that additional information should be required to ensure that the western blots published in scientific publication are not generated images. 

Have a great Sunday!
