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!

Greetings from Pittsburgh!

Today’s digest has a lot of food and agriculture associated articles. Several articles focus on the effects of various pathogens on dairy cows, beef steers, and poultry breeds! For those of us who are more interested in plants, there is an article on biogas production from tomato waste and a preprint on how the microbial community of food waste changes during the composting process. Finally, I included a research article about social media during the pandemic since I’m sure I’m not the only one who has relied on it a little too heavily over the last year…

God morgon!

Good morning from Sweden. Another Monday, a new week, and a new digest.

Today’s digest comes with a new review on gut microbiota focusing on the mycobiota which is mostly overlooked as a bulk of studies focus their interest on bacterial diversity in the gut instead. A very cool feature, which I think is now fast becoming common in papers published in Microbiome is the use of a very informative video abstract. As I mentioned in my previous digest, a video abstract catches the eye and it could very well be the next big thing in academic publishing.

There is some potential bad news from Brazil as a team has identified a new nCoV variant of interest (VoI) which probably originated in August 2020 and accounted for about 3% of all samples analyzed between November 2020 and February 2021. The variant also accounted for a very high fraction (35%) of all the B.1.1.33 lineage samples analyzed during the aforementioned period and is now considered widely distributed in Brazil. The troubling fact is that this variant has a S:E484K mutation in the spike protein and this mutation has been implicated in immune evasion and resistance to several monoclonal antibodies. Speaking about COVID-19, there is a new study that tested the viability of nCoV on various inanimate surfaces. The virus persisted longest on a surgical mask (for about 124 hours) and reduced the fastest on a polyester shirt (about 2.5 hours).

Elsewhere in the digest is a preprint that analysed publically available datasets to determine the effect of space type radiation on the gut microbiome, a somewhat controversial study (check out the comments section) hypothesizing the use of fungus to attenuate ionizing radiation on the ISS, and a comprehensive study of E. coli phage-host interactions within the BASEL phage collection.

Hope you’ll enjoy today’s digest.

God morgon!

Good morning from Sweden. It is hard to believe that it has been a year since the unprecedented happenings of March 2020 but regardless of how we see it, time flies!

The most interesting read of the day is a study that conclusively proves that the oral microbiota is not influenced by your genetics, but by environmental factors. I was intrigued by the use of a video byte, a small video abstract of the paper, which is something new for me. In my opinion, it could very well be the next big thing in academic publishing as it took me just two minutes to understand the whole study! Do check it out!

A promising study is in a preprint where the researchers show that the pre-colonization with a less virulent strain of Clostridioides difficile protects model organisms from subsequent lethal colonization of C. difficile. This has important therapeutic implications in case of nosocomial, antibiotic-promoted diarrhea. Another exciting study shows the influence of gut microbiome on colorectal cancer. The researchers showed that the transplant of ‘good’ microbiota from healthy donors could even reduce the tumorigenesis in the disease models.

Elsewhere in the digest are studies on microbiome of tropical marine sediments, novel proteins from human intestinal microbiome, virulence factors of Trypanosoma brucei, and new therapeutic epitopes in N1 neuraminidase of Influenza virus.
