Malassezia furfur (formerly known as Pityrosporum ovale) is a species of yeast (a type of fungus) that is naturally found on the skin surfaces of humans and some other mammals. It is associated with a variety of dermatological conditions caused by fungal infections , notably seborrhoeic dermatitis and tinea versicolor .
P. ovale was later divided into two species, P. ovale and P. orbiculare, but current sources consider these terms to refer to a single species of fungus, with M. furfur the preferred name. [23] Pityrosporum (Malassezia) pachydermatis, which is lipophilic but not lipid-dependent. It is found on the skin of most animals.
Malassezia folliculitis or pityrosporum folliculitis, [1] is a skin condition caused by infection by Malassezia (formerly Pityrosporum) yeast. [2]: 314 The skin of the upper trunk area including the back, chest, arms and sometimes the neck is often affected and this condition is often seen in young to middle aged adults, although it has been known to occur in adults well into their sixties ...
Species of Malassezia implicated in Seborrhoeic dermatitis include M. furfur (formerly Pityrosporum ovale), M. globosa, M. restricta, M. sympodialis, and M. slooffiae. [ 3 ] Malassezia appears to be the significant factor in seborrhoeic dermatitis but it is thought that other factors are necessary for the presence of Malassezia to result in the ...
Folliculitis is the infection and inflammation of one or more hair follicles.The condition may occur anywhere on hair-covered skin.The rash may appear as pimples that come to white tips on the face, chest, back, arms, legs, buttocks, or head.
The name applied to the fungal agent responsible shifted multiple times over the next 150 years until the genus Pityrosporum was settled upon for the teleomorph, and Malassezia for the anamorph. [8] [9] Through the use of genetic sequencing, a number of new species have since been identified. [2] [8] [10]
Pityrosporum rhinocerosum Sabour Malassezia pachydermatis is a zoophilic yeast in the division Basidiomycota . It was first isolated in 1925 by Fred Weidman, and it was named pachydermatis (Greek for 'thick-skin') after the original sample taken from an Indian rhinoceros ( Rhinocerosus unicornis ) with severe exfoliative dermatitis .
