There is worldwide concern about the constant increase in infections caused by Candida species that are multiresistant to antifungal drugs. The most common candidiasis is caused by Candida albicans, however, the species of the Candida haemulonii complex and Candida auris are emerging opportunistic pathogens, which isolation from clinical samples has significantly increased in the past years. The special interest in the study of these species lies in their ability to evade the action of antifungal drugs, such as amphotericin B, azoles, and echinocandins. In addition, the phenotypic changes of these species have given them the ability to easily adapt to environmental changes, including the host milieu and immunity. In this paper, a detailed review of the current literature on the C. haemulonii complex and C. auris is shown, analyzing aspects such as biology, immune response, putative virulence factors, infection, treatment, and the current strategies for diagnosis.
Keywords: Candida auris; Candida haemulonii complex; antifungal resistance; candidiasis; cryptic Candida species; emerging pathogens; virulence factors.
