Sporothrix schenckii is the species responsible for sporotrichosis, a fungal infection caused by the traumatic implantation of this dimorphic fungus. Recent molecular studies have demonstrated that this species constitutes a complex of numerous phylogenetic species. Since the delineation of such species could be of extreme importance from a clinical point(More)
Two new species in the order Mucorales, Mucor velutinosus and Mucor ellipsoideus, isolated from human clinical specimens in the USA, are described and illustrated. The former species is similar to Mucor ramosissimus, from which it can be differentiated by its ability to grow at 37°C and produce verrucose sporangiospores. Mucor ellipsoideus is also able to(More)
Yeast colonies isolated from vineyard and cellar substrates were analysed in the present study. Yeast species assessment was carried out by amplification and digestion of a region of the ribosomal RNA gene repeat unit. Saccharomyces strains were also characterised using mitochondrial DNA restriction analysis. Oxidative basidiomycetous yeasts without(More)
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(More)
Ninety-two isolates belonging to five species of the Sporothrix schenckii complex were tested in vitro against 12 antifungal agents, using a reference microdilution method. There were significant differences among the species; Sporothrix brasiliensis was the species that showed the best response to antifungals, and S. mexicana had the worst response. In(More)
BACKGROUND Apophysomyces is a monotypic genus belonging to the order Mucorales. The species Apophysomyces elegans has been reported to cause severe infections in immunocompromised and immunocompetent people. In a previous study of Alvarez et al.(3) [J Clin Microbiol 2009;47:1650-6], we demonstrated a high variability among the 5.8S rRNA gene sequences of(More)
Colletotrichum species have caused human infections in recent years. Because of the difficulties in recognizing them in vitro, we have designed a quick and unambiguous molecular test, based on the amplification of a specific fragment of the internal transcribed spacer 1 region, to distinguish any Colletotrichum isolate from other fungi, including the common(More)
The pathogenic dimorphic fungus Sporothrix schenckii is the agent responsible for sporotrichosis, an important fungal infection with a worldwide distribution. Little is known about the population structure of S. schenckii, although recent molecular and phenotypic data seem to demonstrate that different genetic lineages exist within this species. The aim of(More)
Candida nivariensis is a recently described pathogenic yeast closely related to Candida glabrata. We developed a specific set of oligonucleotide primers based on the internal transcribed spacer regions of the rRNA gene for the rapid identification of C. nivariensis. PCR with these primers amplified a 206-bp amplicon from C. nivariensis.
