Only known to us since 2008, Candida auris is an emerging fungal pathogen spreading quickly around the world; alarmingly, it is most commonly found in healthcare settings. C. auris sets itself apart from other Candida species with its unique tolerance to high saline and temperature environments and propensity to develop antifungal resistances that promote its survival in hospitals and healthcare facilities.
Hosts Emily McDonald and Navaneeth Narayanan are joined by fungal experts Dr. Jeffrey Rybak (St. Jude, Memphis TN) and Dr. Graham Snyder (UPMC, Pittsburgh PA) on their quest to better understand C. auris infections, the clinical challenges and knowledge gaps in C. auris research and discuss measures for prevention and containment on the levels of both the patient and the institution.
The recent emergence of C. auris as a multidrug-resistant nosocomial pathogen and its global prevalence has raised more questions than answers. Why now? Why healthcare facilities? Does climate change play a role? Are humans to blame? Tune in to find out what the experts have to say on these questions, and stay to learn about the current therapies available, what is in the antifungal pipeline and how to approach treatment from a stewardship standpoint.
This episode was produced by Angela Huttner, edited by Kathryn Hostettler and peer-reviewed by Dr. Claudio Neidhöfer of University Hospital Bonn, Germany.
