Debaryomyces, the Achilles heel of wound repair.

In a recent Science paper, Jain et al. (2021) discover that a fungus contributes to delayed wound healing in mice and is enriched in inflamed tissue from Crohn's disease patients. This culprit is not a well-known pathogen, but cheese yeast Debaryomyces hansenii, highlighting the importance of further studying fungi-host interactions.
