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 ski...
BACKGROUND Malassezia yeasts are normal flora of the skin that are discovered in 75~98% of health subjects, but since its association with various skin disorders have been known, many studies have been conducted in the distribution of the yeasts. OBJECTIVE To isolate, identify, and classify Malassezia yeasts from the normal human skin of Koreans by using the rapid and accurate molecular biolo...
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...
Malassezia yeast infections are recognized with increasing frequency in veterinary medicine. These opportunistic yeasts cause secondary ear and skin infections that can be extremely pruritic. Within the past 10 years, the Malassezia genus has been divided into seven species. This article describes the new species of Malassezia and their relevance to companion animals. Additionally, recognition,...
Most lipases possess a lid domain above the catalytic site that is responsible for their activation. Lipase SMG1 from Malassezia globose CBS 7966 (Malassezia globosa LIP1), is a mono- and diacylglycerol lipase with an atypical loop-like lid domain. Activation of SMG1 was proposed to be solely through a gating mechanism involving two residues (F278 and N102). However, through disulfide bond cros...
Our understanding of the interactions between normal skin microbiota and the human host has been greatly extended by recent investigations. In their recent study in mBio, A. Gioti et al. (mBio 4[1]:e00572-12, 2013) sequenced the genome of the atopic eczema-associated yeast, Malassezia sympodialis, and compared its gene content and organization with that of Malassezia globosa, a species implicat...
Bioassay-guided fractionation of Chimaphila umbellata (L.) W. Bart (Pyrolaceae) ethanol extracts led to the identification of 2,7-dimethyl-1,4-naphthoquinone (chimaphilin) as the principal antifungal component. The structure of chimaphilin was confirmed by 1H and 13C NMR spectroscopy. The antifungal activity of chimaphilin was evaluated using the microdilution method with Saccharomyces cerevisi...
Background: Malassezia spp. is an opportunistic dimorphicBasidiomycetous fungi associated with a variety of diseasesincluding dandruff, atopic eczema, pityriasis versicolor, seborrheicdermatitis and folliculitis. It also causes systemic infectionsin immune compromised patients. The aim of this study wasto evaluate the antimicrobial activity of nettle leaves (Urticadioica), colocynths fruits (Ci...
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...
In recent years, the genus Malassezia has been expanded based on molecular data; in addition to M. furfur and M. pachydermatis, five new species (M. sympodialis, M. globosa, M. obtusa, M. restricta, M. slooffiae) have been described. Apart from their lipid dependence, little is known about the metabolism and nutritional requirements of these new species. Defined inocula of Malassezia reference ...
