The new species Candida nivariensis, isolated from the clinical samples of three patients in Spain over a 3-year period, is presented here. This species can be easily differentiated from Candida glabrata, the closest genetic species, by different colony color on CHROMagar and by its ability to ferment trehalose. The analyses of the internal transcribed spacer region and the D1-D2 region of the 26S rRNA gene sequences support a new species designation.

SUMMARYMany yeast species causing life-threatening invasive infections that were formerly classified in the genus have been reclassified due to their evolutionary and phylogenetic relationships elucidated by DNA sequencing methods that are increasingly using whole genomes. This review explores the evolving taxonomy, epidemiology, and clinical implications of clinically relevant, rare, emerging and Saccharomycotina yeasts that have recently been reclassified from . This article highlights the urgent need for intensified research efforts to enhance knowledge and improve outcomes in the management of infections caused by these yeasts.

Candida glabrata can exhibit resistance or reduced susceptibility to fluconazole, and there is an increasing frequency of resistance to echinocandins. Candida nivariensis and Candida bracarensis, newly described in 2005 and 2006, respectively, belong to the C. glabrata complex along with C.

Background And Purpose: Onychomycosis is a common fungal infection that affects the nails, caused by various fungal agents. Moreover, yeast onychomycosis has increased in recent years. Yeast isolates might not be identified at the species level by conventional methods, whereas molecular methods can identify yeast isolates more accurately.

The CRISPR-Cas9 system is extremely useful for genome editing in many species, including the model yeast Saccharomyces cerevisiae, and other yeast species. We have previously reported the use of an inducible CRISPR-Cas9 system in Candida glabrata, which allows genome editing but also the study of double-strand break (DSB) repair. We report, in this study, a comparable system for C.

is emerging as a highly resistant species of the complex causing invasive and mucocutaneous infections. In this study, three cases of vulvovaginal candidiasis caused by are described and identified by Internal Transcribed Spacer 1-2 sequencing. All isolates were susceptible in vitro to anidulafungin, micafungin, caspofungin, 5-flucytosine, posaconazole, voriconazole, itraconazole, amphotericin B, and showed dose-dependent susceptibility to fluconazole.
