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 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...

Sporothrix globosa is the main causative agent of sporotrichosis, a common mycosis that usually affects the skin, in China. Despite increasing efforts in the molecular identification of this fungal pathogen, its modes of transmission and epidemiology remain poorly understood. The goals of this study were to assess the genetic diversity of S. globosa using amplified fragment length polymorphism ...

Malassezia folliculitis [MF] is caused by the invasion of hair follicles by large numbers of Malassezia cells, but it remains unclear which Malassezia species are involved in the disease. To clarify this situation, Malassezia species isolated from lesions of MF patients were analyzed by both culture and non-culture methods. In addition, Malassezia species recovered from the non-lesion areas of ...

We experienced an atypical case of pityriasis versicolor with a unique clinical appearance and undescribed mycological features. Although Malassezia sp. was cultured from the keratotic material, the fungal elements observed in the material were not readily identified as Malassezia. The diagnosis was established with the aid of immunohistochemical and ultrastructural studies with the aetiologica...

Oxidative stress leads to formation of free radicals, reactive oxygen species and nitrogen species, which leads to numerous pathophysiological disorders. The present study is aimed to evaluate the free radical scavenging potential of flowers of Gomphrena globosa. The extracts from the flowers of Gomphrena globosa were prepared in solvents viz. methanol, ethanol and butanol. Spectrophotmetric an...

There are differences with respect to the commonly isolated Malassezia species, not only between healthy individuals and the patients with various skin diseases, but also between different countries. We investigated the species composition of Malassezia microflora on the skin of patients with Malassezia-associated diseases and of healthy subjects (HS). Two hundred and fifty skin scrapings from ...

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...

The potential for boosting zinc pyrithione (ZPT) efficacy by using Zemea biobased propanediol in a generic dandruff shampoo formulation was evaluated in this study. A time-dependent, doseresponse relationship was observed between the mortality of Malassezia globosa, a microorganism associated with human dandruff, and Zemea concentration over a range of 0% to 4%. Formulation used in test solutio...

conclusions the nested-pcr is a rapid and repeatable method for identification of important malassezia species and this method is recommended for use on more patients. in addition the most common agents of pityriasis versicolor and seborrheic dermatitis were m. furfur and m. restricta, respectively. results the most common isolate was malassezia furfur (51.3%) followed by m. globosa (35.2%) and...
