Fluconazole-Resistant Candida glabrata Bloodstream Isolates, South Korea, 2008–2018

We investigated the clinical outcomes and molecular mechanisms of fluconazole-resistant (FR) Candida glabrata bloodstream infections. Among 1,158 isolates collected during multicenter studies in South Korea during 2008–2018, 5.7% were FR. For 64 patients with FR bloodstream infection isolates, the 30-day mortality rate was 60.9% and the 90-day mortality rate 78.2%; these rates were significantly higher than in patients with fluconazole-susceptible dose-dependent isolates (30-day mortality rate 36.4%, 90-day mortality rate 43.8%; p
