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...

Background and Purpose: Seborrheic dermatitis is a chronic and recurrent superficial dermatitis in which Malassezia species play an important role. There are different Malassezia species, which have been recently reported to be resistant to common antifungals. Natural sources can be useful alternatives to reduce the emergence of this resistance. Kombucha tea is believed to have potential antimi...

BACKGROUND Pityriasis versicolor (PV) is an infection caused by various species of Malassezia yeast. There is no agreement in the literature concerning the species of Malassezia and the demographic, clinical, and mycological data. AIMS To prospectively identify Malassezia species isolated from lesions of patients with extensive, long standing and recurrent forms of PV and to estimate the rela...

BACKGROUND The Malassezia yeasts which belong to the physiological microflora of human skin have also been implicated in several dermatological disorders, including pityriasis versicolor (PV), atopic dermatitis (AD), and psoriasis (PS). The Malassezia genus has repeatedly been revised and it now accommodates 14 species, all but one being lipid-dependent species. The traditional, phenotype-based...

BACKGROUND AND OBJECTIVES Differences in prevalence, clinical and histological manifestations between seborrheic dermatitis (SD) in immunocompetent and immunocompromised patients suggest that these two populations might also differ in a spectrum of isolated Malassezia species. The purpose of our study was to analyse the prevalence of Malassezia species in immunocompromised and non-immunocomprom...

This research aimed at investigating the cryoprotectant action of glucose and lactose on strains of Malassezia spp. and zygomycetes immobilised in sodium alginate. Twelve strains of Malassezia spp. (nine M. furfur, two M. globosa and one M. sympodialis) and 12 zygomycetes (five Rhizopus oryzae and seven Mucor hiemales) were immobilised in sodium alginate, within plastic beads, maintained in app...

BACKGROUND Seborrheic dermatitis (SD) and Parkinson's disease (PD) are frequently associated conditions. Aims of this study were: to determine severity of SD, presence of different species and density of Malassezia yeasts; to assess yeast lipases and phosphatases production in vitro and to compare these results between SD patients with and without PD. METHODS This case-control prospective stu...

BACKGROUND Malassezia commensal yeasts along with multitude of antigens have been found to be associated with various skin disorders including Pityriasis versicolor (PV). Amongst them Mala s1, a 37 kDa protein has been proved to be a major allergen reacting with a large panel of sera. However, there exists no therapeutic alternative to combat such problems in form of plant based natural compoun...

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...

the present study is designed to evaluate the application of a simple method for rapid identification of malassezia furfur among other malassezia spp. based on production of a brownish-red pigment and its diffusion into the medium containing l-tryptophan as a sigle source of nitrogen.  91 strains of malassezia (20% m. furfur , 2% m. sympodialis , 5% m. obtosa and 73% m. globosa ) isolated from ...
