1. Introduction
Candida auris is an emerging, multi-drug resistant, fungal
pathogen responsible for nosocomial invasive infections [1–4].
C. auris was first described from an external ear canal drainage
specimen from a Japanese patient in 2009 [5]. Although initially
presumed to be a rare pathogen, this species has been
increasingly detected throughout the world in less than a decade
following its first isolation. In June 2016, the Centers for Disease
Control and Prevention (CDC) published an alert for all clinicians,
laboratorians, and public health authorities to report isolation of
C. auris in patients in the United States [1]. The global
epidemiology of this yeast is not well known. Specifically, the
incidence and prevalence rate have not yet been available as this
species is difficult to identify using conventional biochemical
methods [6–9].

Candida auris is an emerging fungal pathogen responsible for nosocomial invasive infection outbreaks on
five continents. Large healthcare-related outbreaks of C. auris infection and colonization have been
reported from different countries. Whole genome sequence analysis identified strong phylogeographic
C. auris clades specific to particular geographical areas suggesting transmission of particular clades
within countries. However, the mode of transmission within the healthcare environment is not clear and
is likely to be multifactorial. The emergence of C. auris is alarming because this organism can harbor or
develop multidrug resistance. This explains why C. auris infections are difficult to treat. In addition,
difficulties in its identification in the routine diagnostic laboratory have a significant impact on outbreak
detection and management. This mini-review highlights the available literature on C. auris, with
particular insight into its epidemiology and the problems caused by its antifungal resistance.
