BACKGROUND The Malassezia yeasts which belong to the physiological microflora of human skin have also been implicated in several dermatological disorders, including pityriasis versicolor (PV), atopic dermatitis (AD), and psoriasis (PS). The Malassezia genus has repeatedly been revised and it now accommodates 14 species, all but one being lipid-dependent species. The traditional, phenotype-based...

Pathogenic microbes secrete various enzymes with lipolytic activities to facilitate their survival within the host. Lipolytic enzymes include extracellular lipases and phospholipases, and several lines of evidence have suggested that these enzymes contribute to the virulence of pathogenic fungi. Candida albicans and Cryptococcus neoformans are the most commonly isolated human fungal pathogens, ...

BACKGROUND: Candida spp and Malassezia cause superficial infections that may be resistant to conventional treatments. Violet light-emitting diodes (LEDs) therapy is a therapeutic alternative. PURPOSE: To describe the protocol for evaluating antifungal effect of violet LEDs 410 nm ± 10 on in vitro. PROTOCOL: are applied fungal suspension at fluences 61.13 J/cm2, 91.70 183.39 J/cm2. The isolates ...

This double-blinded noninferiority clinical trial evaluated the use of oral fluconazole for the treatment of Malassezia dermatitis in dogs by comparing it with use of an accepted therapeutic agent, ketoconazole. Dogs presenting with Malassezia dermatitis were treated with either fluconazole or ketoconazole in addition to cephalexin for concurrent bacterial dermatitis. Statistically significant ...

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...

BACKGROUND Wipes containing chlorhexidine and azole derivates have been recommended for veterinary use. No study has been published about their activity against Malassezia pachydermatis. HYPOTHESIS/OBJECTIVES To evaluate the in vivo and in vitro activity of wipes soaked in a chlorhexidine, climbazole and Tris-EDTA solution against Malassezia pachydermatis. ANIMALS Five research colony shar-...

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 ...

Yeasts of the genus Malassezia are known as the microflora of human skin and that of many warmblooded animals; but the different Malassezia species can induce superficial skin infections. Best known and most frequent is pityriasis versicolor (PV), a chronic and recurrent skin disease occurring primarily in hot and humid climates. The purpose of the present study was to make use of the metabolic...
