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 ...
Malassezia globosa, Malassezia furfur Tinea versicolor (also pityriasis versicolor ) is a condition characterized by a skin eruption on the trunk and proximal extremities. [ 1 ] The majority of tinea versicolor is caused by the fungus Malassezia globosa , although Malassezia furfur is responsible for a small number of cases.
[3] [14] This is based on observations of high counts of Malassezia species in skin affected by seborrhoeic dermatitis and on the effectiveness of antifungals in treating the condition. [14] Species of Malassezia implicated in Seborrhoeic dermatitis include M. furfur (formerly Pityrosporum ovale), M. globosa, M. restricta, M. sympodialis, and M ...
These investigations show that the Malassezia species causing most skin disease in humans, including the most common cause of dandruff and seborrhoeic dermatitis, is M. globosa (though M. restricta is also involved). [1] The skin rash of tinea versicolor (pityriasis versicolor) is also due to infection by this fungus.
Sycosis vulgaris, sycosis barbae, or barber's itch is a staphylococcal infection of the hair follicles in the bearded area of the face, usually the upper lip. Shaving aggravates the condition. Gram-negative folliculitis may appear after prolonged acne treatment with antibiotics. [4]
