    Abstract:
    UNLABELLED: Candida auris is known to survive for weeks on solid material surfaces. Its longevity contributes to medical device contamination and spread through healthcare facilities. We fabricated antifungal surface coatings by coating plastic and glass surfaces with a thin polymer layer to which the antifungal drug caspofungin was covalently conjugated. Caspofungin-susceptible and -resistant C. auris strains were inhibited on these surfaces by 98.7 and 81.1%, respectively. Cell viability studies showed that this inhibition was fungicidal. Our findings indicate that C. auris strains can be killed on contact when exposed to caspofungin that is reformulated as a covalently-bound surface layer. LAY SUMMARY: Candida auris is pathogenic, multidrug resistant yeast with the ability to survive on surfaces and remain transmissible for long periods of time in healthcare settings. In this study, we have prepared an antifungal surface coating and demonstrated its ability to kill adhering C. auris cells on contact.
