Echinocandin Resistance in Candida auris Occurs in the Murine Gastrointestinal Tract Due to < em > FKS1 < /em > Mutations
This study investigated its antifungal susceptibility and explored FKS1 mutations across the isolates from mice enterically colonized with wild-type C. auris and treated with echinocandin. Resistant C. auris with FKS1 mutations, including S639F, S639Y, D642Y, R1354H, or R1354Y, were isolated and found to be micafungin- and caspofungin-resistant in vivo; however, the MICs of isolates with mutation in R1354 remained below the micafungin breakpoint in vitro.PMID:36920237 | DOI:10.1128/aac.01243-22
