Candida spp. with acquired echinocandin resistance, France, 2004-2010.
Résumé
We report 20 episodes of infection caused by acquired echinocandin-resistant Candida spp. harboring diverse and new Fksp mutations. For 12 patients, initial isolates (low MIC, wild-type Fksp sequence) and subsequent isolates (after caspofungin treatment, high MIC, mutated Fksp) were genetically related.
