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 ...

One hundred and thirteen dogs of different breeds and with different clinical forms of external otitis were mycologically and bacteriologically examined. Forty six of those dogs showed abnormal cerumen with a high yeasts contamination. These yeasts belong to four species: Malassezia pachydermatis (80.4%), Cryptococcus laurentii (13.1%), Candida parapsilosis (4.3%) and Trichosporon cutaneum (2.1...

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 techniques rapi...

A novel formulation of RPMI 1640 medium for susceptibility testing of Malassezia yeasts by broth microdilution (BMD) and Etest is proposed. A modification of the NCCLS M27-A2 BMD method was used to test 53 isolates of Malassezia furfur (12 isolates), M. sympodialis (8 isolates), M. slooffiae (4 isolates), M. globosa (22 isolates), M. obtusa (2 isolates), M. restricta (2 isolates), M. pachyderma...

The majority of species within the genus Malassezia are lipophilic yeasts that colonize the skin of warm-blooded animals. Two species, Malassezia globosa and Malassezia restricta, are implicated in the causation of seborrheic dermatitis/dandruff (SD/D). During our survey of SD/D cases, we isolated several species of Malassezia and noticed vast variations within a few lipid-dependent species. Va...

Background and aim: Malassezia species are part of the resident skin flora of humans. These yeasts are associated with various superficial diseases, including seborrheic dermatitis, atopic dermatitis, dandruff, and psoriasis. Various DNA-based molecular methods have been recently described to differentiate species of Malassezia. In this survey, a simple, reliable, and cost effective PCR-b...

Background and Design.Malassezia is a dimorphic fungus which forms part of the normal skin flora, it may exist as budding yeasts in stratum corneum in patients with several cutaneous disease and can cause iatrogenic systemic infections such as fungemia, pulmonary vasculitis, peritonitis in predisposed neonates, children and adults. Malassezia may induce humoral and cellular immunity via activat...

BACKGROUND Seborrheic dermatitis is a common chronic disease. Malassezia yeasts have been implicated in the pathogenesis of this disease. Antifungal agents are known to be effective in the treatment of Malassezia yeast infections. OBJECTIVES To evaluate the efficacy of itraconazole in the treatment of mild to severe facial seborrheic dermatitis. METHODS Sixty patients with moderate to sever...

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...
