Multidimensional assessment of in-host fitness costs of echinocandin resistance in the opportunistic fungal pathogen Candida glabrata reveals the niche-specific requirement for FKS1 and FKS2 during infection and gut colonization.

Abstract excerpt

Host stresses are often considered a major barrier against the emergence of echinocandin resistance (ECR) in prominent infecting organisms like Candida albicans due to fitness defects. Yet, ECR strains of C. glabrata carrying diverse amino acid changes in Fks1 and Fks2 are increasingly reported as breakthrough infections. Nonetheless, the impact of equivalent mutations in different FKS alleles on fitness has not...
