Abstract
Candida parapsilosis is a common cause of invasive candidiasis worldwide and is the most commonly is7olated Candida species among pediatric and neonatal populations. Previous work has demonstrated that nonsynonymous mutations in the gene encoding the putative transcription factor CpMrr1 can influence fluconazole susceptibility. However, the direct contribution of these mutations and how they influence fluconazole resistance in clinical isolates are poorly understood.
