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

Greetings from Pittsburgh!

Today’s digest is unintentionally themed around change. Included is an article on the metabolic versatility of Salmonella enterica and another on the genetic diversification of Escherichia coli. If you’re more interested in the big picture, there is also an article about the evolution of ecological niches in plant-associated microbes as well as an article about the impacts of global change on soil microbial diversity and functionality.

Here’s to hoping that we are just as resilient as the microbes we study!

Events and jobs

A special plug for the National Summer Undergraduate Research Project (NSURP). NSURP is a community-driven initiative to create rewarding remote summer research opportunities for BIPOC undergraduate students in the microbial sciences. They are actively recruiting mentors and students for this summer, with the hope to match pairs by June 22nd.

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!

Today, we present a broad spectrum of new studies covering among others the mycobiome of human milk, gut microbes and their association with brain development and cognitive function, and a catalogue of previously unseen microbial genomes. Of particular interest is a study that integrates different sources of data to model a personalized gut microbiome. Last but not least we selected a pre-print on the design and characterization of multiepitopes vaccine for SARS-CoV.

Good morning! There’s a particularly broad collection of microbiome papers to share with you today, from the bacteria that hang onto wounds after debridement to the biofilms that form in the ancient ruins of a town buried by the eruption of Mount Vesuvius. A few unusual highlights include the sexually transmitted microbiome of bedbugs and the gut microbes that colonize a sea cucumber after it grows up, remove its own digestive tract and grows a new one. Some interesting new software tools are hiding in the “Bioinformatics” section at the bottom as well.
