God morgon!

Good morning from Sweden. I know everyone is looking forward to a long weekend, but today is just Monday.

Today’s digest begins with a new visualisation tool for microbiome analysis in R – animalcules. In another study, probiotic yeast metabolites were reported to inhibit bacterial virulence. It is yet another evidence in support of the fermented milk-based probiotic drinks. Talking about the diet, a team of researchers has found the commonly used dietary emulsifiers have a detrimental impact on the gut microbiome. A new study on studying the microbiome using PCR amplification and sequencing illustrates how off-target amplification can introduce a lot of problems. The study in question compared the brain microbiome of healthy individuals and individuals with Parkinson’s disease. Another study has shown how reduced genome provides certain bacteria an advantage in thriving during coastal dinoflagellate blooms.

Elsewhere in the digest are preprints describing a new broad spectrum antifungal, Kenyan traditional medicine as an approach to tackle antibiotic resistance, and prediction of antibiotic resistance using machine learning approach.

Hope you like today’s collection!
