Abstract

BACKGROUND
The yeasts of genus Malassezia are dimorphic and lipophilic and are numbers of the normal flora in humans. Malassezia yeasts are implicated in various diseases, including pityriasis versicolor, Malassezia folliculitis, seborrheic dermatitis and systemic fungal infections. OBJECT: The study was done to classify the Malassezia yeasts cultured from the lesions of Malassezia folliculitis into one of the revised species and to find out the relationship between certain species of Malassezia and Malassezia folliculitis. METHODs: The specimen obtained from the lesions of twenty cases of Malassezia folliculitis and twenty cases of healthy controls were cultured on Leeming & Notman's media. The obtained strains were placed into one of the seven species by their colony morphologies, microscopic morphologies and physiological characteristics. RESULTS: In the lesions of Malassezia folliculitis, M. globosa occupied most of the cultured colonies in 15 cases, M. restricta in 4 cases and M. furfur in 1 case respectively. In the control group, M. restricta was found to be predominant on the face and M. sympodialis, M. globosa, M. restricta and M. furfur were isolated on the trunk. CONCLUSION: M. restricta and M. globosa could be considered to be mostly implicated species in the seven revised Malassezia species in the lesions of Malassezia folliculitis of the face and trunk respectively.
