A urea broth microdilution method to assay the susceptibilities of seven Malassezia species was developed. This method indicated the same sensitivities as the agar plate dilution method for isolates of Malassezia furfur, M. pachydermatis, M. slooffiae, and M. sympodialis.

During a survey of the occurrence of Malassezia species in the external ear canals of cats without otitis externa, Malassezia furfur was isolated. This is the first report of the isolation of M. furfur from cats.

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 ...

The skin is our first line of defense, protecting us from invasion and evaporation. Its variable structure, changing geography, and complex immune repertoire provide a vast interface for our cutaneous microbial community. Skin is inhabited by many thousands of microbes, but this review focuses on the dominant eukaryote, Malassezia, and its host interaction. Malassezia compromises 17 species wit...

Various C-type lectin receptors (CLRs), including Mincle and Dectin-2, function as pattern recognition receptors and play a central role in immunity to fungal pathogens. However, the precise structures of the CLR ligands in various pathogenic fungi have yet to be completely defined. Here we report that Malassezia, an opportunistic skin fungal pathogen, is cooperatively recognized by Mincle and ...

BACKGROUND Several workers have found that Malassezia are capable of suppressing cytokine release and downregulating the phagocytic function of monocytes. But lipid-depleted Malassezia furfur (M. furfur) extracts have also been shown to induce increased production of TNF-alpha, IL-6 and IL-1beta in monocytes. We thought that the detergents in shampoos or soaps could change the composition of th...

The MICs of ketoconazole and itraconazole against Pityrosporum orbiculare were 0.02 to 0.05 and 0.1 to 0.2 micrograms ml-1, respectively. In a rabbit model, orally administered ketoconazole (1 mg kg-1) afforded protection against experimental pityriasis (tinea) versicolor in all animals. Itraconazole (5 mg kg-1) was effective in four of five rabbits.

BACKGROUND AND OBJECTIVES The genus Malasezia currently includes fourteen species that have been isolated from healthy and diseased human and animal skin. However, there were differences with respect to the species most commonly isolated, not only in patients with various skin diseases but also between healthy individuals. The aim of this study was to analyze the prevalence of Malassezia specie...

During a study on the occurrence of lipid-dependent Malassezia spp. in domestic animals, some atypical strains, phylogenetically related to Malassezia sympodialis Simmons et Guého, were shown to represent novel species. In this study, we describe two new taxa, Malassezia caprae sp. nov. (type strain MA383=CBS 10434), isolated mainly from goats, and Malassezia equina sp. nov. (type strain MA146=...
