Malassezia(redirected from Malassezia furfur (syn. P. orbiculare, P. ovale))
A genus of fungi (family Cryptococcaceae) of low pathogenicity that lack the ability to synthesize medium-chain and long-chain fatty acids and require an exogenous supply of these lipids for growth such as can be found in the skin.
[L. C. Malassez]
Malassezia/Mal·as·se·zia/ (mal″ah-se´zhah) a genus of fungi of the form-class Hyphomycetes, including M. fur´fur, which causes tinea versicolor in susceptible individuals, and M. pachyder´matis.
Etymology: Louis C. Malassez, French physiologist, 1842-1910
a genus of fungi. Malassezia furfur, the species normally found on human skin, can cause tinea versicolor in susceptible hosts (previous name: Pityrosporum oviculare). M. ovalis is a nonpathogenic organism found in sebaceous areas. Formerly called Pityrosporum ovale.
MalasseziaA genus of fungi with 10 known species of lipophilic organisms of the class Exobasidiomycetes, which do not form mycelia. It is a normal skin saprobe which, in the face of immunocompromise in the host, causes opportunistic infections. Malassezia globosa is the most aggressive, and has been causally linked to dandruff, seborrhoeic dermatitis, and the skin rash of tinea versicolor (pityriasis versicolor).
