Superficial Diseases Caused byMalasseziaSpecies

Epidemiology of pityriasis versicolor in Adana, Turkey

“…The diagnosis of PV was established by the characteristic “spaghetti‐and‐meatballs” appearance reflecting the presence of both dense clusters of budding yeast cells, and short hyphae were microscopically observed in 15% potassium hydroxide, and clinical picture when typical hypopigmented or hyperpigmented and scaling lesions were present. In addition, fungal culture was carried out using the composition of modified Dixon agar as follows: 1 L distilled H 2 O, 3.6% malt extract, 0.6% mycological peptone, 2% ox bile, 1% Tween 40, 0.2% glycerol, 0.2% oleic acid, 1.2% agar and 0.5% chloramphenicol 5–7 …”

A study on malassezia micro flora in the skin of healthy individuals in North Kerala, India

“…10,11 Their absolute requirement for lipids and mesophilic nature (optimum temperature being 30-35°C) might explain their presence only on the skin of warm blooded animals. 12 The overall colonization rate of Malassezia spp in normal healthy individuals found in this study was 62.78%. This is in agreement with the studies done in normal healthy Korean subjects at 62.4% and 63.6%.…”

“…The highest detection rates of M. globosa is in agreement with studies from Iran Korea and Spain and stands in contrast with the other studies from India Canada and Russia in which they reported M. sympodialis as the commonest species, Bosnia and Herzegovina as M. restricta and Iran as M. furfur from normal healthy skin. 15,14,25,19,12,16,18 The differences between this study and others may not only be due to the result of variation in species on the skin of individuals in different countries, but also by the difference in sampling methods i.e. ; swabbing, a relatively insensitive method, scraping or adhesive transparent tape method, difference in culture media used (SDA with olive oil, mDA, LNA) and difference in incubation temperature of inoculated culture media.…”

“…A total of 120 apparently healthy men and 120 women without any skin diseases or who were not treated for Malassezia associated skin diseases were selected for the study. They were grouped according to their age as (0-10), (11)(12)(13)(14)(15)(16)(17)(18)(19)(20), (21)(22)(23)(24)(25)(26)(27)(28)(29)(30), (31-40), (41-50), (> 51) where each group consisted of 40 subjects (20 men and 20 women). The specimens consisted of scrapings collected from chest, back and neck from each subject totaling 720 sites.…”

Fungi on the Skin: Dermatophytes and Malassezia

“…Based on this molecular recognition of species, it became possible to differentiate them by phenotypic means to some extent (Guého et al 1996(Guého et al , 1998Guillot et al 1996;Mayser et al 1997;Crespo Erchiga and Guého 2005;Guého-Kellermann et al 2011). Discrimination of closely related species (e.g., M. sympodialis, Malassezia caprae, and Malassezia equine) by these phenotypic methods remains challenging.…”
