<i>Candida auris</i>sp. nov., a novel ascomycetous yeast isolated from the external ear canal of an inpatient in a Japanese hospital

Abstract

A single strain of a novel ascomycetous yeast species belonging to the genus Candida was isolated from the external ear canal of an inpatient in a Japanese hospital. Analyses of the 26S rDNA D1/D2 domain, nuclear ribosomal DNA ITS region sequences, and chemotaxonomic studies indicated that this strain represents a new species with a close phylogenetic relationship to Candida ruelliae and Candida haemulonii in the Metschnikowiaceae clade. This strain grew well at 40 degrees C, but showed slow and weak growth at 42 degrees C. The taxonomic description of Candida auris sp. nov. is proposed (type strain JCM15448T= CBS10913T= DSM21092T).
