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.

Greater galangal rhizomes have been used as medicinal herbs to treat pityriasis versicolor and other diseases. By using a premilinary examination from TLC and the antifungal activity against Pityrosporum orbiculare, a new component was extracted from rhizomes of Alpinia galanga Swartz in Vietnam. The chemical structure of this component was determined by GC-MS and 1H & 13C NMR. Galangal acetate was a colorless, pungent and oily liquid. It showed the antifungal activity against P. orbiculare with MIC = 0.25 ml/ml

Antifungal activity of celery essential oil against Malassezia furfur was investigated using broth microdilution and vapor contact methods. Potent antifungal activity was evident using both methods. Fungicidal activity was revealed in the vapor contact method.

Neonatal Malassezia pustulosis can be defined as pustules on face and neck, age at onset, younger than 1 month, isolation of Malassezia by direct microscopy in pustular material, elimination of other causes of neonatal pustuloses, and response to topical ketoconazole therapy. We report a case of neonatal Malassezia pustulosis in a 20-day-old male. Direct microscopic examination on smears for pustules showed forms of Malassezia yeasts and culture yielded Malassezia sympodialis. The lesions were remarkably improved by topical ketoconazole cream for 14 days.

For the education, sharing the information and research for medical mycology, the Korean Society for Medical Mycology (KSMM) was established in March 9, 1994. Since 1994, meetings of the KSMM have been held annually in June, workshop in August, and symposium in November. The First Symposium Workshop of the KSMM was held on July 12, 1997. Main topics for lectures and practices included identification and microscopic findings of dermatophytes. Also identification of unidentified pathogenic organisms, Malassezia, and Candida were done. The First Mycology Workshop of the KSMM was held on 14 November 1998. Main topics for lectures and practices included identification and microscopic findings of dermatophytes. Also identification of unidentified pathogenic organisms, Malassezia, and Candida were done. Since December 1996, Korean Journal of Medical Mycology, official journal of the KSMM, had been published biannually. Since volume 5 in 2000, it has been published quarterly and one hundred forty copies have been distributed in worldwide.

BACKGROUND: The genus Mulassezia. was recently revised into seven species, M. furfur, M pachydermatis, M sympodialis, M. globosa, M. obtusa, M. restricta and M. slooffiae. Some of the Malassezia species were known to be the etiological agent of pityriasis versicolor. OBJECTIVE: The study was done to place the Malassezia strains cultured from the lesions of pityrisis versicolor into one of The revised species and to elucidate the relationship between certain species and pityriasis versicolor. METHODS: The scales from the lesions of twenty cases of pityrisis versicolor were cultured on Leeming & Notmans media. The obtained strains were placed into one of seven species by their colony morphologies, microscopic morphologies and physiological characteristics. RESULTS: The strains obtained from twenty cases of pityriasis ver sicolor could be placed into one of four species as following incidences. 1 case of M. furfur, 3 cases of M. sympodialis, 15 cases of M globosa, 1 case of M. obtusa, M, globoso occupied the most commonly isolated species cultured from the lesions of pityriasis versicolor. CONCLUSION: The results suggested that M. globosa could be consider ed as a main etiological agent of pityriasis versicolor among the Malassezia species.
