Lipophilic yeasts of the genus Malassezia are part of the normal cutaneous microflora and are considered one of the factors that trigger atopic dermatitis (AD). We isolated two strains of Malassezia from a healthy Japanese female. Analysis of the D1/D2 26S ribosomal DNA and internal transcribed spacer region sequences of the isolates suggested that they are new members of the genus Malassezia. ...

the aim of this study was to assess skin colonization by malassezia species in full-term healthy newborn calves and their dams. two hundred samples from the skins and ears of 50 neonatal calves and their dams were examined on two occasions, first and fourth weeks after birth. all of the samples were determined by cytological examination and fungal culture. the isolated yeasts were identified fo...

background malassezia species as skin microflora of humans and other warm-blooded vertebrates are the lipophilic yeasts associated with various human diseases, especially pityriasis versicolor (pv). objectives the objective of this study was to identify the malassezia species of scraped skin of pv patients in yazd, iran, using morphological, biochemical and physiological methods. we also compar...

Necrotizing infundibular crystalline folliculitis is a rare condition characterized by folliculocentric waxy papules in the seborrheic areas of adult patients, with intrafollicular filamentous birefringent deposits as histopathologic clue. Although real pathogenesis necrotizing remains unclear, material seems to be derived from an interaction between such superficial microorganisms gram-positiv...

Abstract The genus Malassezia is a medically important of yeasts that can colonize the skin humans and other warm-blooded animals. currently comprises 18 species which four new were identified recently. most widely known species, M. pachydermatis , occurs in animals but was detected also humans, namely at life endangering septicaemias prematurely born children. Proliferation frequently as resul...

The killer phenomenon has been used as epidemiological marker for Candida albicans, where hundreds of biotypes can be obtained. The objective of this study is to observe the behaviour of 30 strains of Malassezia pachydermatis isolated from dogs with otitis (15) or dermatitis (15) against 9 killer yeasts, which, when grouped in triplets produced a 3 digit code (biotype). The growth inhibition of...

We have entered the Age of the Microbiome, with new studies appearing constantly and whole journals devoted to the human microbiome. While bacteria outnumber other gut microbes by orders of magnitude, eukaryotes are consistently found in the human gut and are represented primarily by the fungi. Compiling 36 studies 1917-2015 we found at least 267 distinct fungal taxa have been reported from the...

Yeasts of the genus Malassezia serve as both commensal microorganisms and pathogens on the skin of humans and domestic animals. Although rare, cases of life-threatening fungemia in people have been attributed to Malassezia pachydermatis, for which dogs are a natural host. Zoonotic transfer has been documented from dogs to immunocompromised patients by healthcare workers who own dogs. We investi...

The report deals with the five clinical cases of generalized dermatitis associated with Malassezia overgrowth in cats presented to the Faculty of Veterinary Medicine, Jigjiga University, Ethiopia. Elevated numbers of yeasts were observed in lesional skin by cytology and culture. Skin lesions occurred on the face, ventral neck, abdomen and ear canals and were characterized by some degree of alop...
