INTRODUCTION There are limited numbers of studies which focused on the identification of Malassezia yeasts to a species level in onychomycosis. Therefore, the aim of our study was to determine the prevalence and species composition of Malassezia yeasts in patients with clinically suspected onychomycosis and to examine if the range of species varies with patient gender, age, site of involvement ...

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...

background malassezia species as skin microflora of humans and other warm-blooded vertebrates are the lipophilic yeasts associated with various human diseases, especially pityriasis versicolor (pv). objectives the objective of this study was to identify the malassezia species of scraped skin of pv patients in yazd, iran, using morphological, biochemical and physiological methods. we also compar...

BACKGROUND Malassezia species are considered opportunistic yeasts of increasing clinical importance. These lipophilic yeasts are associated with various human diseases, especially pityriasis versicolor (PV), a chronic superficial scaling dermatomycosis. AIMS The aim of this study was to isolate, identify and analyze the distribution of the different species of Malassezia in patients with PV i...

UNLABELLED Malassezia yeasts are found on the skin of all humans and many warm-blooded animals. In vitro they have the ability to synthesize potent ligands (indolo[3,2-b]carbazole, malassezin and indirubin) of the aryl-hydrocarbon receptor (AhR; synonym: dioxin receptor) when the sweat contained L-tryptophan is used as the single nitrogen source. The production of these AhR-ligands has been ass...

Malassezia yeasts are part of the resident cutaneous microbiota, and are also associated with skin diseases such as seborrheic dermatitis (SD). The role these fungi play in skin diseases and why they are pathogenic for only some individuals remain unclear. This study aimed to characterize Malassezia microbiota from different body sites in healthy and SD subjects from Brazil. Scalp and forehead ...

BACKGROUND Malassezia species play an important role in the pathogenesis of seborrheic dermatitis. In particular, M. restricta and M. globosa are considered to be the predominant organisms in seborrheic dermatitis of Western countries. However, species distribution of Malassezia in seborrheic dermatitis has not been clearly determined yet in Asia. OBJECTIVE To identify the distribution of Mal...

Malassezia species are members of the human cutaneous commensal flora, in addition to causing a wide range of cutaneous and systemic diseases in suitably predisposed individuals. Studies examining cellular and humoral immune responses specific to Malassezia species in patients with Malassezia-associated diseases and healthy controls have generally been unable to define significant differences i...

BACKGROUND So far, studies on the inter-relationship between Malassezia and Malassezia folliculitis have been rather scarce. OBJECTIVE We sought to analyze the differences in body sites, gender and age groups, and to determine whether there is a relationship between certain types of Malassezia species and Malassezia folliculitis. METHODS Specimens were taken from the forehead, cheek and che...
