Delighted that our review on resistance to last-resort antibiotics in Enterococci has been published in FEMS Microbiology Reviews

TL;DR: the Enterococci are really good at evolving resistance to antibiotics in new and creative ways.
Resistance to last-resort antibiotics in enterococci
Abstract. The genus Enterococcus comprises a diverse group of species, many of which are commensal members of the gut microbiota of humans and animals. The

Urban vs rural lifestyles create dramatically different gut microbiomes. But how do these different gut microbiomes affect the host?

The #TMHMS25 has just wrapped up!
It’s been four amazing days of stimulating discussions and sharing our science in a wonderfully relaxed and supportive atmosphere.
There was a truly genuine sense of community among all participants, which I really cherish.

Cheers, to the next one! 🌊

Tree evolution is surprisingly quirky! 🌳 Trees are likely ancestral in many plant groups, often re-evolve on islands, and Arabidopsis can be made tree-like by tweaking a few genes. We revisited what genes really make a tree a tree using comparative genomics. @trhvidsten.bsky.social #trees #evolution

Like here our criteria was that >70% of genes in a an enriched pathway had to be present, including the "key" genes required for proper functioning. One enriched gene says little, but we try to make it as unlikely that we're focusing on statistical accidents.
