February 27th, 2021

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!
