The order Mucorales comprises predominantly fast-growing saprotrophic fungi, some of which are used for the fermentation of foodstuffs but it also includes species known to cause infections in patients with severe immune or metabolic impairments. To inventory biodiversity in Mucorales ITS barcodes of 668 strains in 203 taxa were generated covering more than(More)
The in vitro susceptibilities of 66 molecularly identified strains of the Mucorales to eight antifungals (amphotericin B, terbinafine, itraconazole, posaconazole, voriconazole, caspofungin, micafungin, and 5-fluorocytosine) were tested. Molecular phylogeny was reconstructed based on the nuclear ribosomal large subunit to reveal taxon-specific susceptibility(More)
The aim of this study was to assess potential candidate gene regions and corresponding universal primer pairs as secondary DNA barcodes for the fungal kingdom, additional to ITS rDNA as primary barcode. Amplification efficiencies of 14 (partially) universal primer pairs targeting eight genetic markers were tested across > 1 500 species (1 931 strains or(More)
Mucormycosis usually presents as a progressive infection with significant angio-invasion. Mucormycosis due to Mucor irregularis (formerly Rhizomucor variabilis var. variabilis), however, is exceptional in causing chronic cutaneous infection in immunocompetent humans, ultimately leading to severe morbidity if left untreated. More than 90 % of the cases known(More)
Global distribution patterns of Cladophialophora carrionii, agent of human chromoblastomycosis in arid climates of Africa, Asia, Australia, Central-and South-America, were compared with similar data of the vicarious Fonsecaea spp., agents of the disease in tropical rain forests. Population diversities among 73 C. carrionii strains and 60 strains of three(More)
The study describes isolation of Neoscytalidium dimidiatum from a case of eosinophilic fungal rhinosinusitis (EFRS). The isolate was identified by routine mycological methods and confirmed by DNA sequencing of the internal transcribed spacer (ITS) region of rDNA. To our knowledge, this is the first report of its kind from Iran.
We report the case of a 66-year-old Iranian woman with a phaeohyphomycotic cyst (approximately 3×2.5cm in size) on the right lateral side of the neck. She had dysphagia and hoarseness, without any pain. She complained about discharge of black liquid on the skin and irritation. Histological examination of biopsy fragments from the lesions showed septate,(More)
Rhizopus microsporus has been used for centuries in the production of oriental fermented foods, but the species is also known as a toxin producer and from severe human infections. To study the diversity and species delimitation of Rhizopus microsporus, 48 isolates from the reference collection of the CBS-KNAW Fungal Biodiversity Centre, comprising nine(More)
Rhizopus arrhizus (Mucorales, Mucoromycotina) is the prevalent opportunist worldwide among the mucoralean species causing human infections. On the other hand the species has been used since ancient times to ferment African and Asian traditional foods and condiments based on ground soybeans. As producer of organic acids and hydrolytic enzymes it is widely(More)
Deep infections by melanized fungi deserve special attention because of a potentially fatal, cerebral or disseminated course of disease in otherwise healthy patients. Timely diagnostics are a major problem with these infections. Rolling circle amplification (RCA) is a sensitive, specific and reproducible isothermal DNA amplification technique for rapid(More)
