Introduction. The lipophilic yeasts of genus Malassezia are the members of the resident skin microflora in humans and other warm-blooded animals [ 1, 2].These yeasts are associated with some skin diseases, such as pityriasis versicolor (PV), seborrheic dermatitis, scalp dandruff, atopic dermatitis, and folliculitis [ 3, 4].
Skin conditions caused or aggravated by infection by malassezia include: Pityriasis versicolor – most often due to M. globosa, M. sympodialis and M. furfur. Malassezia folliculitis due to the yeast growing in the hair follicles where they produce inflammation. Steroid acne. Seborrhoeic dermatitis, dandruff, sebopsoriasis and facial or scalp

Most studies carried out in recent years support our hypothesis —proposed in 1999— that Malassezia globosa is the predominant species in pityriasis versicolor
Sep 29, 2020 · Pityriasis versicolor (PV) also known as tinea versicolor is caused by basidiomycetous yeasts of the genus Malassezia, characterized by lipid-dependent growth [ 1 – 3] and narrow specialization in the context of occupied ecological niches [ 2 ]. With respect to human skin, species of the genus Malassezia may have positive as well as negative
