Research progress in antifungal resistance mechanisms in Candida auris / 中华微生物学和免疫学杂志

ABSTRACT

Candida auris ( C. auris) is a recently emerged multidrug-resistant fungal pathogen, featured by difficulty in identification, high mortality and easy spread in hospital environments. Furthermore, C. auris is resistant to various frontline antifungals. However, the mechanisms governing drug resistance remain unclear. This review summarized the mechanisms of triazole resistance in C. auris, including ERG11 missense mutations or overexpression, the activity of efflux pumps, missense mutations in TAC1 B, the gain of an extra copy of chromosomeⅤ, the role of Hsp90 and biofilm formation. In addition, the factors associated with the resistance to other drugs including echinocandins, polyenes, nucleoside analogues and acrylamide were also reviewed.
