background: members of the malassezia genus are often lipophilic, observed as budding yeasts and found as commensals in the skin of humans. this genus opportunistically reside in several areas including scalp where under the influence of particular predisposing factors, their proliferation is increased (e.g., high activation of sebaceous glands), and leads to dandruff and seborrheic dermatitis,...

BACKGROUND Malassezia yeasts are normal flora of the skin that are discovered in 75~98% of health subjects, but since its association with various skin disorders have been known, many studies have been conducted in the distribution of the yeasts. OBJECTIVE To isolate, identify, and classify Malassezia yeasts from the normal human skin of Koreans by using the rapid and accurate molecular biolo...

Background and Design.Malassezia is a dimorphic fungus which forms part of the normal skin flora, it may exist as budding yeasts in stratum corneum in patients with several cutaneous disease and can cause iatrogenic systemic infections such as fungemia, pulmonary vasculitis, peritonitis in predisposed neonates, children and adults. Malassezia may induce humoral and cellular immunity via activat...

materials and methods in total, among 134 patients clinically suspected of having pityriasis versicolor, attending the department of mycology, boali sina hospital and referral laboratory of the mazandaran university of medical sciences, 116/134 (86.5%) positive patients for malassezia elements, namely, yeast cells and short hyphae in microscopic examination, were included in the study. all 116 ...

BACKGROUND Pityriasis versicolor is a superficial infection of the stratum corneum which caused by a group of yeasts formerly named pityrosporium. The taxonomy of these lipophilic yeasts has recently been modified and includes seven species referred as Malassezia. The aim of this study is to compare the distribution of Malassezia species isolated from pityriasis versicolor lesions and those iso...

Forty-six strains of Malassezia spp. with atypical biochemical features were isolated from 366 fresh clinical isolates from human subjects and dogs. Isolates obtained in this study included 2 (4.7%) lipid-dependent M. pachydermatis isolates; 1 (2.4%) precipitate-producing and 6 (14.6%) non-polyethoxylated castor oil (Cremophor EL)-assimilating M. furfur isolates; and 37 (34.3%) M. slooffiae iso...

BACKGROUND The lipophilic yeasts of Malassezia species are members of the normal skin microbial that are cause of pityriasis versicolor. Pityriasis versicolor is a common superficial fungal infection with world-wide distribution. The phenotypic methods for identification of Malassezia species usually are time consuming and unreliable to differentiate newly identified species. But DNA-based tech...

BACKGROUND Malassezia commensal yeasts along with multitude of antigens have been found to be associated with various skin disorders including Pityriasis versicolor (PV). Amongst them Mala s1, a 37 kDa protein has been proved to be a major allergen reacting with a large panel of sera. However, there exists no therapeutic alternative to combat such problems in form of plant based natural compoun...

The genus Malassezia comprises commensal yeasts on human skin. These yeasts are involved in superficial infections but are also isolated in deeper infections, such as fungemia, particularly in certain at-risk patients, such as neonates or patients with parenteral nutrition catheters. Very little is known about Malassezia epidemiology and virulence. This is due mainly to the difficulty of distin...
