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 ...

It is a multifactorial disease that requires several predisposing factors for its progress. Presence of these factors leads to reproduction of opportunistic yeast Malassezia spp [2]. The fungus uses lipids from the skin surface to produce unsaturated and saturated fatty acids which, when left in the individual’s skin milieu, induce an inflammatory response. The sebum in the skin aids the growth...

The skin of mammalian organisms is home for a myriad of microbes. Many of these commensals are thought to have beneficial effects on the host by critically contributing to immune homeostasis. Consequently, dysbiosis can have detrimental effects for the host that may manifest with inflammatory diseases at the barrier tissue. Besides bacteria, fungi make an important contribution to the microbiot...

 Abstract Background: Psoriasis is a chronic proliferative condition of the skin. Its accurate pathogenesis has not been known yet, but interactions between genes and environmental factors have been implicated in its initiation. The role of malassezia in psoriasis is still undetermined, but several reports have associated these lipophilic yeasts with the development of skin lesions in psoriasis...

An evaluation was made of the phospholipase activities of Malassezia pachydermatis strains isolated from healthy dogs versus those from dogs with dermatitis and otitis. A high percentage of strains of M. pachydermatis obtained from lesion sites (93.9%) produced phospholipase, compared to the strains obtained from healthy skin of the same dog with localized lesions (41.4%) and healthy dogs (10.6%).
