Several human skin diseases and disorders are associated with two groups of fungi, the dermatophytes and Malassezia. Although these skin-related problems are not generally life threatening, they are among the most common diseases and disorders of mankind. These fungi are phylogenetically divergent, with the dermatophytes within the Ascomycota and Malassezia within Basidiomycota. Genome analysis...

BACKGROUND Malassezia pachydermatis is a yeast of importance in both veterinary and human medicine. AIMS To know if M. pachydermatis grow on mycological media with high concentrations of gentamycin. METHODS Twenty M. pachydermatis strains were streaked on Sabouraud Dextrose Agar plates with different concentrations of gentamycin. RESULTS All isolates were inhibited when high concentration...

We report a case of seborrheic blepharitis treated with oral itraconazole during a short period. Direct examination using Parker KOH revealed numerous hyphae and spores of Malassezia in the scale. Low-dose itraconazole pulse therapy (200 mg daily, 7 days a month) was quite effective. This is the second case in which we also observed a unique fungal conformation which looked like tinea versicolo...

Pityriasis versicolor is a superficial infection of the stratum corneum, which is caused by the Malassezia species. Tge Malassezia species consist of 12 subspecies, including M. furfur, M. pachydermatis, M. symphodialis and M. globasa. The Malassezia species are classified as a normal flora, particularly in the sebum rich areas of the skin, and they convert from saprophytic yeast to parasitic m...

Although pityriasis versicolor is the only human disease for which Malassezia yeasts have been fully established as pathogens, it is still not clear which species are implicated. Most studies carried out in recent years support our hypothesis —proposed in 1999— that Malassezia globosa is the predominant species in pityriasis versicolor lesions, at least in temperate climates. Confirmation of th...

We investigated Malassezia species and genotypes colonizing dogs, comparing those recovered from the ear canal with those from other anatomical body sites, as well as from diseased and healthy skin. The Malassezia isolates were obtained from four types of skin samples, i.e., diseased ear, diseased skin, healthy ear, and healthy skin. Sequences of the 26S ribosomal DNA region, the intergenic spa...

the lipophilic yeasts of malassezia species are members of the normal skin microbial that are cause of pityriasis versicolor. pityriasis versicolor is a common superficial fungal infection with world-wide distribution. the phenotypic methods for identification of malassezia species usually are time consuming and unreliable to differentiate newly identified species. but dna-based techniques rapi...

Lipophilic yeast of the genus Malassezia (Pityrosporum) belongs to the normal flora of human skin and many warm-blooded animals. These fungi can produce a diverse range of diseases that the best known and most frequent of them is pityriasis versicolor, a chronic recurrent skin disease occurring primarily in tropical regions. The genus Malassezia has been recently enlarged to include seven disti...
