The killer effect of 36 Hansenula, Pichia, Saccharomyces, and Candida species on 26 hyphomycetes isolates, 1 isolate of the achlorophyllous microorganism Prototheca, 4 isolates of the lipophilic yeast Malassezia, 1 isolate of the aerobic actinomycete Nocardia, and 19 isolates of bacteria was studied. The killer phenomenon, which was previously considered to be restricted to yeasts, was found to...

Malassezia spp. form part of the normal human cutaneous flora and are implicated in several mild, but recurrent cutaneous diseases, such as pityriasis versicolor, Malassezia folliculitis, seborrhoeic dermatitis, and, with lesser frequency, a range of other dermatological disorders. Malassezia spp. have also been associated with cutaneous and systemic diseases in immunocompromised patients inclu...

abstract background: psoriasis is a chronic proliferative condition of the skin. its accurate pathogenesis has not been known yet, but interactions between genes and environmental factors have been implicated in its initiation. the role of malassezia in psoriasis is still undetermined, but several reports have associated these lipophilic yeasts with the development of skin lesions in psoriasis....

Exposure and sensitization to fungal allergens can promote the development and worsening of allergic diseases. Although numerous species of fungi have been associated with allergic diseases in the literature, the significance of fungi from the genera Alternaria, Cladosporium, Penicillium, Aspergillus, and Malassezia has been well documented. However, it should be emphasized that the contributio...

Background: Malassezia spp. is an opportunistic dimorphicBasidiomycetous fungi associated with a variety of diseasesincluding dandruff, atopic eczema, pityriasis versicolor, seborrheicdermatitis and folliculitis. It also causes systemic infectionsin immune compromised patients. The aim of this study wasto evaluate the antimicrobial activity of nettle leaves (Urticadioica), colocynths fruits (Ci...
