An Unconventional Oral Candidiasis in an Immunocompetent Patient

Alessandra Fusco et al. J Fungi (Basel). .

Abstract

Oral candidiasis (OC) is an opportunistic fungal infection of the oral mucosae, sustained by Candida albicans or other non-albican Candida species (NAC), usually eradicated by conventional antifungals of the classes of azoles, polyenes, or derivative from echinocandins. OC usually occurs under predisposing local or systemic factors. C. lusitaniae is an opportunistic strain that is rarely responsible for human infection and occurs mainly in severe immunocompromised states. The present work reported an unconventional case of OC in an otherwise healthy immunocompetent woman sustained by C. lusitaniae and a multi-resistant strain of C. albicans.

Keywords: Candida spp.; antimycogram; biofilm; hyphae; oral candidiasis; yeast cell.
