[Malassezia infections].

Although Malassezia yeasts are a part of the normal microflora, under certain conditions they can cause superficial skin infection Pityriasis versicolor, Malassezia folliculitis. Lipophilic yeasts are being considered as major opportunistic pathogens for a very long time. Most of the yeasts show an absolute requirement for long fatty acid chains and specific procedures are required for their isolation, conservation and identification. To date, the genus is composed of one non lipid-dependent species M. pachydermatis and lipid-dependent species M. furfur, M. sympodialis, M. globosa, M. obtusa, M. restricta, M. slooffiae, M. dermatis, M. yamatoensis, M. japonica, M. nana, M. caprae, M. equina, M. cuniculi.
