Molecular Characterization of Candida auris Isolates at a Major Tertiary Care Center in Lebanon

Popis výsledku v původním jazyce

BackgroundThe globally emerging Candida auris pathogens poses heavy burden to the healthcare system. Their molecular analyses assist in understanding their epidemiology, dissemination, treatment, and control. This study was warranted to describe the genomic features and drug resistance profiles using whole genome sequencing (WGS) among C. auris isolates from Lebanon. MethodsA total of 28 C. auris clinical isolates, from different hospital units, were phenotypically identified by matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) and tested for antifungal resistance using Vitek-2 system and E test. The complete genomes were determined by WGS using long reads sequencing (PacBio) to reveal the clade distribution and antifungal resistance genes. ResultsCandida auris revealed uniform resistance to fluconazole and amphotericin B, with full susceptibility to echinocandins. Among key resistance genes studied, only two mutations were detected: Y132F in ERG11 gene and a novel mutation, D709E, found in CDR1 gene encoding for an ABC efflux pump. Phylogenetically, C. auris genomes belonged to South Asian clade I and showed limited genetic diversity, suggesting person to person transmission. ConclusionThis characterization of C. auris isolates from Lebanon revealed the exclusivity of clade I lineage together with uniform resistance to fluconazole and amphotericin B. The control of such highly resistant pathogen necessitates an appropriate and rapid recovery and identification to contain spread and outbreaks.
