“…More than 20 studies (Tables 3 to 6) have been carried out worldwide on the epidemiology of Malassezia species in cases of pityriasis versicolor, seborrheic dermatitis, atopic eczema, and psoriasis and on healthy control skin of the same individuals or skin from healthy volunteers (53,63,89,112,122,146,171,173,180,185,228,237,255,259,275,286,344,353). Results are not directly comparable between studies, as different methodologies, isolation media, and identification procedures have been employed.…”

SUMMARY In the last 15 years, the genus Malassezia has been a topic of intense basic research on taxonomy, physiology, biochemistry, ecology, immunology, and metabolomics. Currently, the genus encompasses 14 species. The 1996 revision of the genus resulted in seven accepted taxa: M. furfur , M. pachydermatis , M. sympodialis , M. globosa , M. obtusa , M. restricta , and M. slooffiae. In the last decade, seven new taxa isolated from healthy and lesional human and animal skin have been accepted: M. dermatis , M. japonica , M. yamatoensis , M. nana , M. caprae , M. equina , and M. cuniculi. However, forthcoming multidisciplinary research is expected to show the etiopathological relationships between these new species and skin diseases. Hitherto, basic and clinical research has established etiological links between Malassezia yeasts, pityriasis versicolor, and sepsis of neonates and immunocompromised individuals. Their role in aggravating seborrheic dermatitis, dandruff, folliculitis, and onychomycosis, though often supported by histopathological evidence and favorable antifungal therapeutic outcomes, remains under investigation. A close association between skin and Malassezia IgE binding allergens in atopic eczema has been shown, while laboratory data support a role in psoriasis exacerbations. Finally, metabolomic research resulted in the proposal of a hypothesis on the contribution of Malassezia -synthesized aryl hydrocarbon receptor (AhR) ligands to basal cell carcinoma through UV radiation-induced carcinogenesis.

“…Na República Dominicana, de 100 pacientes analisados, 61% estavam na faixa de 11 a 30 anos, com predomínio do sexo feminino (62%) e com lesões freqüentemente localizadas no tronco (70%) 1 . A maior colonização no tronco e dorso pode ser explicada pela elevada densidade de glândulas sebáceas nesta área, o que preenche o requerimento de ácidos graxos exigidos pelas leveduras lipofílicas como M. furfur 10 .…”

[18][19][20] This study revealed only pure cultures of a single Malassezia isolated from one site in healthy individuals. This is in variance with a study done on Tunisian healthy normal subjects in which (13.32%) showed mixed cultures of different Malassezia spp including M. globosa + M. sympodialis (4.44%), M. globosa +M.…”

Background: Malassezia spp are accounted for approximately 60-90% of the total cutaneous fungal micro biota. An enhanced understanding of the distribution of Malassezia spp in healthy individuals is necessary to gain insight to involvement of these species in human skin disorders particularly in pityriasis versicolor. The aim of this study was to assess the Malassezia micro flora of healthy individuals and to identify species variation with different body sites, gender and age groups.Methods: A total of 120 apparently healthy men and 120 women without any skin diseases or who were not treated for Malassezia associated skin diseases were selected for the study. The specimens consisted of scrapings collected from chest, back and neck from each control subject totaling 720 sites.Results: The recovery rate of Malassezia was positive in case of 452 (62.78%) of 720 sites sampled, while the remaining 268 (37.22%) were found to be negative. Recovery rate of Malassezia was highest in chest with 83.33% positive cases, followed by the back with 73.33% and the neck 31.67%. M. globosa was identified as the common species (46.46%) followed by M. furfur (25%) and M. restricta (22.56%). No significant difference was present (P > 0.05) in distribution of species with different body sites, gender and age groups.Conclusions: The overall colonization rate of Malassezia spp in normal healthy individuals found in this study was 62.78%. M. globosa was identified as the common species (46.46%).

Abstract: From these findings it was suggested that M. globosa presents the main species implicated in the pathogenicity of PV and M. furfur as the second agent of importance.
