In this study we compare the capability of amplification fragment-length polymorphism (AFLP) and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) to identify and subtype isolates of members of the Candida parapsilosis complex (C. parapsilosis, C. orthopsilosis, C. metapsilosis) and Lodderomyces elongisporus, which cannot be differentiated with biochemical methods. Both techniques correctly identified all isolates included in this study and clustered isolates within the different species. DNA-based and mass spectrum-based dendrograms yielded similar outcomes with regard to phylogenetic distance within C. orthopsilosis and C. parapsilosis species. However, a different clustering was obtained for C. metapsilosis for which AFLP was highly effective in differentiating. While MALDI-TOF MS was found to be a reliable method for species-level identification, further studies are required to assess its value as a fungal typing tool.

This study addresses the use of other echinocandins as surrogate markers to predict the susceptibility of rezafungin against the six most common spp. The Clinical Laboratory Standards Institute (CLSI) reference broth microdilution method was performed to test 5,720 clinical isolates of six different species. Species-specific interpretative criteria by CLSI breakpoints or epidemiological cutoff values were applied.

Background: The epidemiology of vulvovaginal candidiasis (VVC) in Greece remains poorly reported and outdated.
Objectives: We therefore conducted a 2-year retrospective survey to assess the epidemiological aspects of the infection among symptomatic Greek patients.
Patients/methods: High vaginal swab samples were collected from adult women with clinically suspected VVC attending a private diagnostic laboratory in Athens.

Background: Humidity between the toes and occlusion are risk factors and causes of recurrence for interdigital tinea pedis.
Objective: To determine the role of wearing "finger-socks" in addition to topical antifungal treatment in managing interdigital tinea pedis.
Methods: Among 54 patients with interdigital tinea pedis confirmed by direct microscopy, 31 in the study group were recommended to wear five-finger socks in addition to topical antifungal treatment for four weeks, while 23 in the control group received only topical antifungal treatment without sock recommendations.

Candida is a commensal fungus of clinical interest that commonly lives in oral cavity and intestine but can become an opportunist microrganism and cause severe infections. A serie of 10 aminochalcones were designed and synthetized to obtain compounds anti-Candida with potent and broad-spectrum activity. The most active compound J34 demonstrated excellent in vitro activity against Candida albicans, Candida tropicalis, Candida parapsilosis, Candida glabrata and Candida krusei with minimum inhibitory concentration between 1.

We report the discovery of small molecules that target the RNA tertiary structure of self-splicing group II introns and display potent antifungal activity against yeasts, including the major public health threat . High-throughput screening efforts against a yeast group II intron resulted in an inhibitor class which was then synthetically optimized for enhanced inhibitory activity and antifungal efficacy. The most highly refined compounds in this series display strong, gene-specific antifungal activity against .
