Many species of fungi have been detected in the healthy human gut; however, nearly half of all taxa reported have only been found in one sample or one study. Fungi capable of growing in and colonizing the gut are limited to a small number of species, mostly Candida yeasts and yeasts in the family Dipodascaceae (Galactomyces, Geotrichum, Saprochaete). Malassezia and the filamentous fungus Clados...

Dandruff is a prevalent chronic inflammatory skin condition of the scalp that has been associated with Malassezia yeasts. However, the microbial role has not been elucidated yet, and the etiology of the disorder remains poorly understood. Using high-throughput 16S rDNA and ITS1 sequencing, we characterized cutaneous bacterial and fungal microbiotas from healthy and dandruff subjects, comparing ...

BACKGROUND A new shampoo with anti-Malassezia properties obtained from various plants is required to provide seborrheic dermatitis patients with a wider range of treatment options. OBJECTIVE The aim of this study was to obtain in vitro susceptibility profiles of Malassezia restricta and M. globosa, the most important pathogenic organisms in the development of seborrheic dermatitis, to the pla...

We report the results of a study which aim was the mycological identification of specimens coming from patients included in a clinical trial. A total of 445 specimens from patients with clinical diagnosis of dermatomicosis were processed during 8 months (138 pityriasis versicolor, 28 cutaneous candidosis and 279 dermatophytosis). A 48% of pityriasis versicolor cultures were positive for Malasse...

BACKGROUND So far, studies on the inter-relationship between Malassezia and Malassezia folliculitis have been rather scarce. OBJECTIVE We sought to analyze the differences in body sites, gender and age groups, and to determine whether there is a relationship between certain types of Malassezia species and Malassezia folliculitis. METHODS Specimens were taken from the forehead, cheek and che...

Abstract Yeasts, usually defined as unicellular fungi, occur in various fungal lineages. Hence, they are not a taxonomic unit, but rather represent lifestyle shared by several unrelated Although the discovery of new yeast species occurs at an increasing speed, current rate it will likely take hundreds years, if ever, before all be documented. Many parts earth, including many threatened habitats...

Introduction Otitis is a frequent problem in dogs – in many cases we deal with a recurrent problem. Looking at the etiology we have to take into account bacterial infections, yeasts (Malassezia spp.), parasites (Otodectes cynotis as well as Demodex species) and foreign bodies. Less often we deal with neoplasia, allergies (especially food intolerance), autoimmune diseases or endocrinopathies tha...

Seborrheic dermatitis is a chronic relapsing inflammatory skin disorder clinically characterized by scaling and poorly defined erythematous patches. The prevalence of adult seborrheic dermatitis is estimated at 5%. Although the exact cause of seborrheic dermatitis has yet to be understood, Malassezia yeasts, hormones (androgens), sebum levels and immune response are known to play important role...

Malassezia (Pityrosporum) species are lipophilic yeasts that are recognized as commensals of the skin of warm-blooded vertebrates. Aryl-hydrocarbon receptor (AhR) ligands produced by Malassezia species have been implicated in carcinogenesis, suggesting that this yeast may contribute to the development of skin cancer, particularly basal cell carcinoma (BCC). This hypothesis suggests that skin ca...
