Cryptococcus neoformans and Cryptococcus gattii are pathogenic yeasts causing meningoencephalitis in immunocompromised and immunocompetent hosts. The fungus is typically haploid, and sexual reproduction occurs normally between individuals with opposite mating types, α and a. C. neoformans var. grubii (serotype A) is comprised of molecular types VNI, VNII,(More)
Human and animal fungal pathogens are a growing threat worldwide leading to emerging infections and creating new risks for established ones. There is a growing need for a rapid and accurate identification of pathogens to enable early diagnosis and targeted antifungal therapy. Morphological and biochemical identification methods are time-consuming and(More)
Aspergillus terreus has a worldwide distribution in soil, constitutes the third most important cause of invasive aspergillosis in humans and is classically regarded as a strictly asexual species. Strains of A. terreus were characterized by ITS, β-tubulin and calmodulin sequences. Mating type was identified by amplifying and sequencing MAT1-1 and MAT1-2(More)
Three commercial rabbit farms independently reported suspected dermatophyte infections during 2004. Cultures confirmed that the infection was caused by the zoophilic Tricophyton mentagrophytes, while mating studies and sequencing of the internal transcribed spacer (ITS)1/4 polymerase chain reaction products, directly amplified from skin lesions and from(More)
BACKGROUND Trichophyton raubitschekii is a dermatophyte belonging to the T. rubrum complex and is differentiated principally by its positive urease activity and production of profuse macroconidia and microconidia in culture. It is classically isolated from African, South-east Asian and Australian aboriginal patients with tinea corporis or tinea cruris. (More)
In this study, the first such study in Greece, we used polyphasic identification combined with antifungal susceptibility study to analyze Aspergillus clinical isolates comprising 102 common and rare members of sections Fumigati, Flavi, Terrei, Nidulantes, Nigri, Circumdati, Versicolores, and Usti. High amphotericin B MICs (>2 μg/ml) were found for 17.6% of(More)
Fungal peritonitis is a rare, potentially lethal, complication of continuous ambulatory peritoneal dialysis (CAPD). We report what we believe to be the first confirmed Neosartorya hiratsukae CAPD-related peritonitis case in Europe. The patient died, despite early removal of the peritoneal catheter and antifungal therapy. This report highlights the impact of(More)
BACKGROUND Infections caused by Malassezia yeasts are most likely underdiagnosed, because fatty acid supplementation is needed for growth. Rapid identification of Malassezia species is essential for appropriate treatment of Malassezia-related skin infections, fungaemia and nosocomial outbreaks in neonates, children and adults and can be life-saving for(More)
The commercial yeast identification systems API ID32C, Auxacolor, and Vitek were evaluated using 251 molecularly identified bloodstream isolates and 2 reference strains, representing a total of 35 species (6 common and 29 rare). Correct identification rates were higher for common species (Auxacolor, 95%; API ID32C, 94%; Vitek, 92%) than for rare species(More)
Trichosporon yeasts constitute emerging pathogens, implicated in organ-specific and systemic infections. In this first, comprehensive study of Trichosporon clinical isolates in Greece, 42 isolates were identified by sequencing the hypervariable D1/D2 domain of the Large Subunit (LSU) rDNA gene, while Trichosporon asahii were genotyped by sequencing the(More)
