Abstract Background and Objective: Malassezia yeast is considered lipophilic normal flora of human skin and warm-blooded vertebrates. This fungus is an opportunistic pathogen in causing seborrheic dermatitis. In this study, the yeasts isolated from the crust of the patients with seborrheic dermatitis were identified by PCR-Sequencing. Material and Methods: In this study, 65 ...

Yeasts of the genus Malassezia are known as the microflora of human skin and that of many warmblooded animals; but the different Malassezia species can induce superficial skin infections. Best known and most frequent is pityriasis versicolor (PV), a chronic and recurrent skin disease occurring primarily in hot and humid climates. The purpose of the present study was to make use of the metabolic...

Members of the genus Malassezia have rarely been associated with lagomorphs. During the course of an investigation of the lipophilic mycobiota of rabbit skin, two lipid-dependent isolates which could not be identified were recovered on Leeming and Notman agar medium from different animals. No growth of Malassezia yeasts was obtained either on Sabouraud's glucose agar or modified Dixon agar medi...

Malassezia folliculitis [MF] is caused by the invasion of hair follicles by large numbers of Malassezia cells, but it remains unclear which Malassezia species are involved in the disease. To clarify this situation, Malassezia species isolated from lesions of MF patients were analyzed by both culture and non-culture methods. In addition, Malassezia species recovered from the non-lesion areas of ...

BACKGROUND The lipophilic yeasts of Malassezia species are members of the normal skin microbial that are cause of pityriasis versicolor. Pityriasis versicolor is a common superficial fungal infection with world-wide distribution. The phenotypic methods for identification of Malassezia species usually are time consuming and unreliable to differentiate newly identified species. But DNA-based tech...

Malassezia species (previously Pityrosporum) are normal flora of human and warm-blooded animals skin. The genus Malassezia is now divided into 13 species. Most of the yeasts show an absolute requirement for long fatty acid chains and specific procedures are required for their isolation, conservation and identification. Under appropriate conditions, the fungi can cause various skin diseases. Th...

The aim of the study was the isolation of genus Malassezia species in healthy dogs, and their identification since there are ten known species and their number increases every year. Dixon medium is considered to be the best for Malassezia isolation, and the results of the study proved to be so. Of all the 74 Malassezia strains isolated, 71 were M. pachydermatis, 2 M. furfur and one M. globosa. ...

BACKGROUND This case-control study concerns a molecular biological method based on the data gathered from a group of Korean subjects to examine the distribution of Malassezia yeasts in seborrheic dermatitis (SD) patients. Cultures for Malassezia yeasts were taken from the foreheads, cheeks and chests of 60 patients with SD and in 60 healthy controls of equivalent age. OBJECTIVE The purpose of...

BACKGROUND AND OBJECTIVES In recent years, the genus Malassezia has come to be considered important in the etiology of seborrhoeic dermatitis (SED). The aim of present study was identification of Malassezia species on the lesions of Iranian SED patients. METHODS 100 patients with SED were enrolled in the study. The patients were evaluated both clinically for the severity of SED and microscopi...

During a study on the occurrence of lipid-dependent Malassezia spp. in domestic animals, some atypical strains, phylogenetically related to Malassezia sympodialis Simmons et Guého, were shown to represent novel species. In this study, we describe two new taxa, Malassezia caprae sp. nov. (type strain MA383=CBS 10434), isolated mainly from goats, and Malassezia equina sp. nov. (type strain MA146=...
