A Human Ex Vivo Skin Model to Study Candida auris Biofilms

Methods Mol Biol. 2022:2517:259-267. doi: 10.1007/978-1-0716-2417-3_21.

Abstract

Candida auris can persist for long periods on hospital surfaces and on the skin. C. auris has the ability to form drug-resistant biofilms, which can substantially impact on patient outcome. In comparison to Candida albicans, C. auris has a lower capacity to form biofilms in in vitro models and a higher capacity when tested on animal skin models. Intraspecies variation is shown to exist, with some clinical isolates having greater biofilm capabilities than others. There is a need for models that closely mimic the real niches where infection occurs on human patients. This protocol describes, in detail, a human skin model to study C. auris biofilm formation using catheterized and non-catheterized skin.
