Novel application of the masson-fontana stain for demonstrating Malassezia species melanin-like pigment production in vitro and in clinical specimens.
نویسندگان
چکیده
Melanin-like pigment produced in vitro and in vivo by Malassezia yeasts has not been described before. Masson-Fontana staining confirmed accumulation of black pigment on the cell walls of L-dihydroxyphenylalaline (L-DOPA)-cultured Malassezia species. Black pigment was also observed in cells and hyphae from hyperpigmented patient lesions with culture-confirmed pityriasis versicolor and seborrheic dermatitis.

متن کاملRapid Identification of Malassezia furfur from other Malassezia Species: A Major Causative Agent of Pityriasis Versicolor
The present study is designed to evaluate the application of a simple method for rapid identification of Malassezia furfur among other Malassezia spp. based on production of a brownish-red pigment and its diffusion into the medium containing L-tryptophan as a sigle source of nitrogen. 91 strains of Malassezia (20% M. furfur, 2% M. sympodialis, 5% M. obtosa and 73% M. globosa) isolated from ski...
متن کاملIsolation and Characterization of Melanin Producing Pseudomonas stutzeri Strain UIS2 in the Presence of l-tyrosine and Survey of Biological Properties of Its Melanin
Background: Melanin is a negative charge hydrophobic complex pigment. Melanin is produced naturally in bacteria to protect them against UV, free radicals and environmental stresses. Pigment production in bacteria has more advantages than other biosources due to its rapid growth, higher efficiency and easier extraction. The aim of this study was the isolation, biochemical and molecular identific...
متن کاملThe Role of L-DOPA on Melanization and Mycelial Production in Malassezia Furfur
Melanins are synthesized by organisms of all biological kingdoms and comprise a heterogeneous class of natural pigments. Certain of these polymers have been implicated in the pathogenesis of several important human fungal pathogens. This study investigated whether the fungal skin pathogen Malassezia furfur produces melanin or melanin-like compounds. A melanin-binding monoclonal antibody (MAb) l...
متن کاملDermoscopy of Pigmented Bowen's Disease Mimicking Early Superficial Spreading Melanoma
A 89-year-old Japanese woman presented at our clinic because of a several months' history of an asymptomatic gradually enlarging pigmented skin lesion on the dorsum of the left foot. Physical examination revealed a single hyperpigmented oval macule of 5 mm with a rough surface. The color of the lesion was dark brown to light brown. Dermoscopic examination demonstrated atypical pigment network w...
