PURPOSE Malassezia yeasts are globally distributed agents of pityriasis versicolor and are implicated in the pathogenesis of seborrhoeic and atopic dermatitis. The aim of this study is to identify the Malassezia species obtained from pityriasis versicolor patients, using morphological, biochemical, physiological as well as Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-...

Malassezia yeasts are commensal microorganisms, which under insufficiently understood conditions can become pathogenic. We have previously shown that specific strains isolated from diseased human skin can preferentially produce agonists of the aryl hydrocarbon receptor (AhR), whose activation has been linked to certain skin diseases. Investigation of skin scale extracts from patients with Malas...

INTRODUCTION There are limited numbers of studies which focused on the identification of Malassezia yeasts to a species level in onychomycosis. Therefore, the aim of our study was to determine the prevalence and species composition of Malassezia yeasts in patients with clinically suspected onychomycosis and to examine if the range of species varies with patient gender, age, site of involvement ...

BACKGROUND Although acne is a common follicular inflammatory dermatosis, studies of the relationship between Malassezia yeasts and acne have rarely been conducted. OBJECTIVE We sought to identify Malassezia yeasts from acne patients and establish a relationship between specific types of species of Malassezia and acne. METHODS Sixty acne patients were enrolled. Each strain obtained was ident...

Cultures for Malassezia yeasts were taken from both normal-looking skin and lesional skin in 124 patients with atopic dermatitis, 16 patients with seborrhoeic dermatitis and from normal skin of 31 healthy controls. Positive Malassezia growth was found in fewer patients with atopic dermatitis (56%) than in patients with seborrhoeic dermatitis (88%) or in healthy controls (84%, p<0.01). In the pa...

The present study was aimed to investigate the prevalence of Malassezia in common ear affections of dogs. A total of 115 dogs with ear affections were evaluated between March 2014 and May 2015. Otoscopic examination and microbiological isolation was done for diagnosis. Case prevalence of Malassezia infection in otitis externa was 19.1%. Relatively higher proportion of Malassezia was found in ma...

BACKGROUND A Pyrosequencing assay has been used in identification of fungal species such as Candida or Aspergillus and diagnosis of pathogenic bacteria such as Helicobacter pylori but there has been no report on successful isolation and identification of Malassezia yeasts using the pyrosequencing method. OBJECTIVE Examine the applicability and plausibility of the pyrosequencing method in iden...

Malassezia yeasts are associated with several dermatological disorders. The conventional identification of Malassezia species by phenotypic methods is complicated and time-consuming, and the results based on culture methods are difficult to interpret. A comparative molecular approach based on the use of three molecular techniques, namely, amplified fragment length polymorphism (AFLP) analysis, ...

Malassezia pachydermatis is a saprophytic yeast commonly found on normal and abnormal skin of dogs. Malassezia pachydermatis and staphylococci play a significant role in seborrheic dermatitis. Malassezia dermatitis (MD) is common and should be considered in any case exhibiting erythematous, oily, and pruritic dermatitis (1). Specialty dermatology practices may see 2 or more cases of MD a week. ...

Malassezia furfur is the lipophilic yeast which causes tinea versicolor and is an uncommon cause of fungaemia. It usually occurs in the context of hyperalimentation with lipid emulsion, immunosuppression, or the presence of a central venous catheter. We report a case of a ventilator-dependent patient who developed Malassezia furfur fungaemia in the absence of these known risk factors. A likely ...
