Greetings Everyone,
I want to began the month of July on a note that diversity is the basis for life. I can’t think of anything better to teach us about diversity, co-existence, and evolution than the fascinating Microbiome.
The microbiome affects us right from our birth till the end affecting our mental as well as physical health. The microbiome exhibits all sorts of differences in shape, size, color, metabolic functions in order to sustain life.
Much to learn from these tiny beings!!!!
Today’s Digest comprises of some interesting studies about effect of microbiome on chemotherapy and studies on tumor microbiome. It also includes articles exploring genetics of gut microbiome and the role of microbiome in inflammatory bowel disease. Additionally has a news article about taking microbiome therapies to clinical trials.
Hope you enjoy reading today’s digest!!
“Life on earth is such a good story you cannot afford to miss the beginning… Beneath our superficial differences we are all of us walking communities of bacteria. The world shimmers, a pointillist landscape made of tiny living beings”. – Lynn Margulis

Hallo und Guten Morgen from Germany! I hope you are well and have the time and energy to enjoy some microbiome related reading hours. I included a number of interesting reviews, related to mental and general health, soil microbiome and amphibian skin microbiome.
There is also a nice variety of new microbe research, including the influence of temperature changes on the microbiome of lizards and the microbiome’s association with heat tolerance, seasonal cycles of microbial communities in the Baltic Sea and the influence of hydrocarbons pollutants on the human skin microbiome.

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.

God morgon!

Good morning from Sweden. It’s a new week and a new month! I hope everyone is doing good and staying healthy during these tough times. Like the tradition, today’s digest opens with COVID 19 related articles. There is an interesting Q&A article that provides a lot of important information. There is an article that focused on the disease progression and recovery from COVID in children and found out that Computerized Tomography (CT) may not be the best tool when it comes to analyzing COVID in children. Apart form COVID 19, there is also some new interesting information from the structure of Type-IV pilus. Elsewhere in the digest is an article on an easy to use toolkit for microbiome analysis and development of a new path-breaking point-of-care system for rapid detection of mycobacteria.

Hope you’ll enjoy and learn something new from today’s digest!

Hello and welcome to today’s microbiome digest! It’s a compact digest, but quite diverse. You will find a study investigating the effect of high-fat diet in Drosophila found a microbiota-dependent activation of stem-cells; electronic cigarettes were found to negatively influence the oral microbiome, and glycan epitopes present on enveloped viruses (as COVID-19) can be targeted and neutralized by human antibodies against these foreign glycan structures.
Finally, a helpful article during Corona-times, when more and more courses and meetings are held online, features the use of FAIR training material: Ten simple rules for making training materials FAIR. Enjoy!

There is also the Cell paper (highlighted) from Peter Turnbaugh’s group on ketogenic diets and the gut microbiome, which has been getting a lot of press. For new bioinformatic and other techniques, we have a new R package to predict functional profiles in Tax4Fun2, an assessment of phylogenetic rooting methods for bacteria, and a description of fiber intervention used in undergraduate classes for active learning.

May 20, 2020

Greetings from Pittsburgh, PA!

Television and movies are a welcome distraction from the current global pandemic. For this digest, I’d like to highlight two articles. The article by Sajjad et al. investigates the possibility of resurrection of ancient microbes present in the natural frozen world and is a perfect pair for the monster-of-the-week X-Files episode “Ice.” The second highlighted article focuses on the microbiome present on two ancient Slavonic parchment codices and how this data can be used to provide additional historical context. Maybe Harrison Ford can team up with Piñar et al. to create a fourth movie in the Indiana Jones Franchise based on their work?

Happy reading, everyone!
