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.

Commensal microbes and humans have coevolved toward a symbiotic relationship. In healthy individuals, the human microbiome has vital role in development of innate adaptive immune system, inducing protective regulatory immunity, system maintains an optimal balance microbes. Several acute chronic skin conditions are result imbalances host-microbiome relationship accompanied by epidermal barrier d...

In this study we compare the reproductive biology of Cordia globosa and C. leucocephala (Cordiaceae, Boraginales; formerly referred to Boraginaceae) to understand the functioning of the floral morphs and the relations with their effective pollinators. The species are synchronopatric, distylic, and self-incompatible. Though they share melittophilous traits, the main visitor and pollinator of C. ...

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=...

When different growth phases (exponential or stationary) or forms (solitary cells or colonies) of a single clone of Phaeocystis globosa were fed to three copepods, grazing, measured indirectly by fecal-pellet production, on different types of P. globosa differed by nearly two orders of magnitude, with differences on this clone sometimes exceeding differences between different phytoplankton spec...

Seborrheic dermatitis (SD) is a common skin condition seen frequently in clinical practice. The use of varying terms such as sebopsoriasis, seborrheic dermatitis, seborrheic eczema, dandruff, and pityriasis capitis reflects the complex nature of this condition. Despite its frequency, much controversy remains regarding the pathogenesis of SD. This controversy extends to its classification in the...

Malassezia yeasts are commensal microorganisms, which under insufficiently understood conditions can become pathogenic. We have previously shown that specific strains isolated from diseased human skin can preferentially produce agonists of the aryl hydrocarbon receptor (AhR), whose activation has been linked to certain skin diseases. Investigation of skin scale extracts from patients with Malas...

Sporothrix globosa is a thermo-dimorphic fungus belonging to a pathogenic clade that also includes Sporothrix schenckii, which causes human and animal sporotrichosis. Here, we present the first genome assemblies of two S. globosa strains providing data for future comparative genomic studies in pathogenic Sporothrix species.
