Insights into the Unique Nature of the East Asian Clade of the Emerging Pathogenic Yeast Candida auris.

The emerging yeast can be highly drug resistant, causing invasive infections, and large outbreaks. went from an unknown pathogen a decade ago to being reported in over thirty countries on six continents. consists of four discrete clades, based on where the first isolates of the clade were reported, South Asian (clade I), East Asian (clade II), African (clade III), and South American (clade IV). These clades have unique genetic and biochemical characteristics that are important to understand and inform the global response to Clade II has been underrepresented in the literature despite being the first one discovered. In this issue of the , Y. J. Kwon et al. (J Clin Microbiol 57:e01624-18, 2019, https://doi.org/10.1128/JCM.01624-18) describe the largest collection of clinical isolates from Clade II, which is also the longest-running span of clinical cases, 20 years, from any single region to date. Clade II appears to have a propensity for the ear that is uncharacteristic of the other clades, which typically cause invasive infections and large-scale outbreaks. This study provides new information on an understudied lineage of and has important implications for future surveillance.
