Abstract

BACKGROUND: Malassezia yeasts were suggested to be one of the etiologic factors of seborrheic dermatitis. The genus Malassezia was recently revised into seven species. OBJECT: The study was done to classify the Malassezia yeasts cultured from the lesions of seborrheic dermatitis into one of the revised species and to find out the relationship between certain species of Malassezia and seborrheic dermatitis.
METHODS
The specimen obtained from the lesions (face) of twenty cases of seborrheic dermatitis 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
M. restricta occupied most (more than seventy percents) of the cultured colonies in 13 cases, M. globosa in 6 cases and M. furfur in 1 case respectively.
CONCLUSION
M. restricta could be considered to be mostly implicated species in the seven revised Malassezia species in the lesions of seborrheic dermatitis of the face.
