One in, one out: Commensal fungus protects against infection

Abstract

Gut-resident fungi have a broad influence over health and disease. In this issue of JEM, Sekeresova Kralova et al. (https://doi.org/10.1084/jem.20231686) identify a commensal yeast that displaced fungal pathogen Candida albicans and protected against subsequent invasive infections that originate from the gut.
