BACKGROUND Superficial mycoses are fungal infections limited to the outermost layers of the skin. Dermatophytic filamentous fungi and yeasts are the major causative agents of these mycoses. Dermatophytosis is one of the clinical conditions caused by fungal infections most commonly found in dermatological practice. Thus, knowledge of the ecology of dermatophytes provides a better understanding o...

The maintenance of Malassezia pachydermatis in fungal collections is very important for retrospective and prospective studies. The aim of this study was to evaluate the behavior of Malassezia pachydermatis in different storage methods. After the identification process, M. pachydermatis strains were stored for six and nine months, in saline and saline plus mineral oil at 28 degrees C, as well as...

Malassezia species are members of the human cutaneous commensal flora, in addition to causing a wide range of cutaneous and systemic diseases in suitably predisposed individuals. Studies examining cellular and humoral immune responses specific to Malassezia species in patients with Malassezia-associated diseases and healthy controls have generally been unable to define significant differences i...

Malassezia folliculitis [MF] is caused by the invasion of hair follicles by large numbers of Malassezia cells, but it remains unclear which Malassezia species are involved in the disease. To clarify this situation, Malassezia species isolated from lesions of MF patients were analyzed by both culture and non-culture methods. In addition, Malassezia species recovered from the non-lesion areas of ...

Seborrheic dermatitis is a common chronic disease. Malassezia yeasts have been implicated in the pathogenesis of this Antifungal agents are known to be effective treatment yeast infections. This study was done evaluate efficacy itraconazole seborrheic dermatitis. Sixty patients with were evaluated an open non-comparative study. Patients treated capsule 100 mg twice day for week; then after 3-we...

Dandruff is characterized by a flaky, pruritic scalp and affects up to half the world's population post-puberty. The aetiology of dandruff is multifactorial, influenced by Malassezia, sebum production and individual susceptibility. The commensal yeast Malassezia is a strong contributory factor to dandruff formation, but the presence of Malassezia on healthy scalps indicates that Malassezia alon...

Flor yeast strains represent a specialized group of Saccharomyces cerevisiae yeasts used for the production sherry-like wines by biological wine aging. We sequenced genome industrial flor strain I-329 from collection microorganisms winemaking “Magarach” and metagenomes two velums based on this continuously maintained several decades. The winery uses processes wine: batch aging continuous proces...

OBJECTIVE To correlate the density of the yeast Malassezia with the clinical seventy of seborrhoeic dermatitis. METHOD Fifty patients and twenty control subjects were selected for the study. The patients were evaluated both clinically for the severity of seborrhoeic dermatitis and microscopically for the presence of the yeast Malassezia. RESULTS Out of 50 patients Malassezia was present in ...

Psoriasis, a common cutaneous disease of unknown etiology, may be triggered by infections, including those due to fungi. Since the fungal community of human skin is poorly characterized, we aimed to analyze the mycological microbiota in healthy skin and psoriatic lesions. Twenty-five skin samples from five healthy subjects (flexor forearm) and three patients with psoriasis were analyzed using b...

Malassezia spp in skin microbiome scalp has been implicated in seborrheic dermatitis pathogenesis. Thus, treatment based in antifungal combined to topical keratolitic agents have been indicated as well as oral isotretinoin as it reduces the sebum production, glandular's size and possesses anti-inflammatory properties. This randomized, comparative and therapeutic trial aimed toper form the genot...
