Malassezia yeast infections are recognized with increasing frequency in veterinary medicine. These opportunistic yeasts cause secondary ear and skin infections that can be extremely pruritic. Within the past 10 years, the Malassezia genus has been divided into seven species. This article describes the new species of Malassezia and their relevance to companion animals. Additionally, recognition,...

Yeasts of the genus Malassezia are part of the normal flora of human skin. However, they are also associated with various skin diseases. Since the introduction of Malassezia to the Korean Dermatologic Society two decades ago, remarkable progress has been made in our knowledge of this genus. In this paper, we review recent developments in Malassezia research, including taxonomy and methods for s...

BACKGROUND The Malassezia genus includes mainly lipophilic yeasts belonging to the cutaneous microbiota of man and other mammals. Some Malassezia species have been associated with various dermatological diseases. The factors permitting the transformation of yeasts of the Malassezia genus from a commensal organism to a pathogenic agent are still little known but the production of various enzymes...

BACKGROUND Skin pigmentary changes of pityriasis versicolor may occur as either hyperpigmented or hypopigmented lesions, depending on the outcome of interactions between Malassezia yeasts and the skin, such as lipoperoxidation process, stimulus of inflammatory cell to melanocytes, and increased thickness of keratin layer. OBJECTIVE To investigate skin characteristic factors that enhance the s...

The objectives of this study were to investigate the frequency of pityriasis versicolor occurrence and to identify yeasts of the genus Malassezia in patients at the mycology laboratory of the Federal University of Goiás, in Goiânia, State of Goiás. Ninety-five cases of pityriasis versicolor were diagnosed, and four species of Malassezia were identified: Malassezia furfur, Malassezia sympodialis...

Malassezia is a genus of lipid-dependent yeasts. It is associated with common skin diseases such as pityriasis versicolor and atopic dermatitis and can cause systemic infections in immunocompromised individuals. Owing to the slow growth and lipid requirements of these fastidious yeasts, convenient and reliable antifungal drug susceptibility testing assays for Malassezia spp. are not widely avai...

BACKGROUND Malassezia species are considered opportunistic yeasts of increasing clinical importance. These lipophilic yeasts are associated with various human diseases, especially pityriasis versicolor (PV), a chronic superficial scaling dermatomycosis. AIMS The aim of this study was to isolate, identify and analyze the distribution of the different species of Malassezia in patients with PV i...

The present study aimed at detection and species-level identification of the Malassezia yeasts in domestic animals and aquatic birds by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Samples were collected using tape strips and swabs from 471 animals including 97 horses, 102 cattle, 105 sheep, 20 camels, 60 dogs, 30 cats, 1 hamster, 1 squirrel, 50 aquatic birds a...

Members of the genus Malassezia have rarely been associated with lagomorphs. During the course of an investigation of the lipophilic mycobiota of rabbit skin, two lipid-dependent isolates which could not be identified were recovered on Leeming and Notman agar medium from different animals. No growth of Malassezia yeasts was obtained either on Sabouraud's glucose agar or modified Dixon agar medi...
