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...

Dandruff is a common problem in both teens and adults. This study to evaluate the role of bacteria fungi associated with dandruff seborrheic dermatitis. Malassezia furfur (70%) was predominant isolate, followed by globosa (30%) which included mixed infection (15%) M. together adding as significant causative agents (p < 0.00001) compared healthy teens. A qualitative in-vitro susceptibility perfo...

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,...

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 skin...

The in vitro activity of a new triazole R126638 against Malassezia yeasts was compared with that of ketoconazole. With the agar dilution technique, minimal inhibitory concentrations were lower for R126638 compared with ketoconazole against Malassezia globosa, M. obtusa, M. slooffiae, M. restricta and two strains of M. sympodialis. On human stratum corneum in vitro, both R126638 and ketoconazole...

PURPOSE Malassezia yeasts are globally distributed agents of pityriasis versicolor and are implicated in the pathogenesis of seborrhoeic and atopic dermatitis. The aim of this study is to identify the Malassezia species obtained from pityriasis versicolor patients, using morphological, biochemical, physiological as well as Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-...

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 ...

BACKGROUND Although acne is a common follicular inflammatory dermatosis, studies of the relationship between Malassezia yeasts and acne have rarely been conducted. OBJECTIVE We sought to identify Malassezia yeasts from acne patients and establish a relationship between specific types of species of Malassezia and acne. METHODS Sixty acne patients were enrolled. Each strain obtained was ident...
