background: malassezia are dimorphic, lipid-dependent yeasts, which are responsible for causing several cutaneous and sys­temic conditions. although cyclophilins (cyps) are highly conserved cytosolic proteins that catalyze the peptidyl-prolyl cis-trans isomerazation reaction before protein folding process, it has been suggestive of an allergen in a few numbers of fungi such as aspergillus fumig...

BACKGROUND Skin pigmentary changes of pityriasis versicolor may occur as either hyperpigmented or hypopigmented lesions, depending on the outcome of interactions between Malassezia yeasts and the skin, such as lipoperoxidation process, stimulus of inflammatory cell to melanocytes, and increased thickness of keratin layer. OBJECTIVE To investigate skin characteristic factors that enhance the s...

background: members of the malassezia genus are often lipophilic, observed as budding yeasts and found as commensals in the skin of humans. this genus opportunistically reside in several areas including scalp where under the influence of particular predisposing factors, their proliferation is increased (e.g., high activation of sebaceous glands), and leads to dandruff and seborrheic dermatitis,...

By molecular identification and typing, we have been able to analyze the pathogenicity and relationship between Malassezia-related diseases and species of this genus.

BACKGROUND A type of neonatal cephalic pustulosis that is clinically similar to classic neonatal acne recently has been linked to Malassezia furfur infection. To correlate the mycological and clinical findings in neonates with cephalic pustulosis, we carried out a prospective case-control study in a neonatal unit from February to April 1997 using new techniques for classifying Malassezia specie...

UNLABELLED Malassezia commensal yeasts are associated with a number of skin disorders, such as atopic eczema/dermatitis and dandruff, and they also can cause systemic infections. Here we describe the 7.67-Mbp genome of Malassezia sympodialis, a species associated with atopic eczema, and contrast its genome repertoire with that of Malassezia globosa, associated with dandruff, as well as those of...

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...

Currently, the genus Malassezia includes 14 species, which have been identified traditionally based on their morphology and biochemical features (Cafarchia et al., 2011). Since the description of new species a number of studies have evolved to elucidate the role of the different species in the ecology and pathogenicity in a range of dermatoses, in which variable results have been reported from ...

BACKGROUND AND OBJECTIVES The genus Malassezia contains an expanding list of lipophilic yeasts involve in the etiology of various superficial fungal infections. Pityriasis versicolor (PV) is the most prevalent Malassezia-related infection distributed worldwide. In the present study, clinical and epidemiological features of the genus Malassezia are discussed with special focus on PV in Iran. M...
