BACKGROUND Malassezia species normally colonize the skin but they can change their saprophytic state and invade the stratum corneum as pathogens. AIMS To determine the prevalence of Malassezia species isolated from patients with pityriasis versicolor (PV) and to analyse their distribution according to the location of the lesion on the body. METHODS This study included 218 patients with PV a...

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...

During a survey of the occurrence of Malassezia species in the external ear canals of dogs with chronic otitis externa, lipid-dependent Malassezia species were isolated in three dogs. These species were identified as Malassezia furfur and M. obtusa but showed atypical assimilation patterns. To our knowledge, this is the first report of the isolation of lipid-dependent species of the genus Malas...

Forty-six strains of Malassezia spp. with atypical biochemical features were isolated from 366 fresh clinical isolates from human subjects and dogs. Isolates obtained in this study included 2 (4.7%) lipid-dependent M. pachydermatis isolates; 1 (2.4%) precipitate-producing and 6 (14.6%) non-polyethoxylated castor oil (Cremophor EL)-assimilating M. furfur isolates; and 37 (34.3%) M. slooffiae iso...

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. ...

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...

conclusions patients who regularly use the local saunas had poor personal hygiene and greasy skin, and were more suspected to tinea versicolor infection. results the disease was more prevalent in 21-40 years old age group in both genders. the most infected anatomical regions were posterior surface, the body trunk (shoulder, supra scapula and lumbar region), anterior thorax and abdomen, respecti...

An in-house prepared M. furfur antigen was used to carry out a seroprevalence study in an urban population in Malaysia by indirect immunofluorescence assay. Of the 800 serum samples from all ages screened, 738 samples were positive for M. furfur specific IgG, giving an overall seropositive rate of 92.3%. There was no significant difference in the seropositive rates among the different gender gr...

Antifungal activity of celery essential oil against Malassezia furfur was investigated using broth microdilution and vapor contact methods. Potent antifungal activity was evident using both methods. Fungicidal activity was revealed in the vapor contact method.

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...
