Microbe Profile: Candidozyma auris: an emergent and resilient yeast and new antifungal strategies.

Candidozyma auris is an emerging opportunistic yeast that is important because of its multidrug resistance, persistence in healthcare environments and ability to cause outbreaks. Since its discovery in 2009 in Japan, it has rapidly spread worldwide and is now recognized as a major global public health threat and was recognized by the World Health Organization (WHO) in 2022 as a critical priority fungal pathogen. Distinct phylogeographic clades demonstrate simultaneous emergence on different continents, suggesting ecological or environmental triggers. Clinical management is complicated by frequent resistance to fluconazole, reduced susceptibility to amphotericin B and echinocandins, and frequent misidentification by traditional laboratory methods. Continued genomic surveillance, improved diagnostics and new antifungal strategies are urgently needed, supported by enhanced infection prevention and control procedures.
