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.

Happy reading!
