Effectiveness of FastFung agar in the isolation of Malassezia furfur from skin samples.

Mycoses 2022 Jul 25;65(7):704-708. Epub 2022 May 25.

Department of Medical Microbiology, Medical Faculty, Cukurova University, Adana, Turkey.

Background: Lipophilic basidiomycetous yeasts of the Malassezia genus can cause various skin diseases, such as seborrheic dermatitis, pityriasis versicolor, folliculitis and atopic dermatitis, and even life-threatening fungemia in newborns and immunocompromised individuals. Routine mycological media used in clinical practice do not contain sufficient lipid ingredients required for the growth of Malassezia species. A recently developed medium, FastFung agar, is promising for culturing fastidious fungal species. Read More

Difficulties in diagnosing Malassezia furfur bloodstream infection and possibility of spontaneous resolution in a patient undergoing chemotherapy for neuroblastoma: A case report.

J Infect Chemother 2022 Jul 9;28(7):987-990. Epub 2022 Mar 9.

Department of Infectious Diseases, Nagoya University Hospital, Aichi, Japan; Department of Infectious Diseases, Nagoya University Graduate School of Medicine, Aichi, Japan.

Malassezia furfur is a lipophilic, yeast-like fungus that forms part of the normal human skin microflora and is associated with a wide range of infections, such as pityriasis versicolor, folliculitis, and systemic infections in immunocompromised patients. Although matrix-assisted laser desorption/ionization time-of-flight mass spectrometry has enabled rapid identification of Malassezia species, it is still a challenge to diagnose systemic infections because Malassezia fungemia can often be missed by automated blood culture systems. We report a case in which M. Read More

St. Johns Institute of Dermatology, Kings College London, London, United Kingdom.

Yeasts of the genus, , formerly known as , are lipophilic yeasts, which are a part of the normal skin flora (microbiome). colonize the human skin after birth and must therefore, as commensals, be normally tolerated by the human immune system. The yeasts also have a pathogenic potential where they can, under appropriate conditions, invade the stratum corneum and interact with the host immune system, both directly but also through chemical mediators.

Successful treatment of Pityriasis Versicolor by photodynamic therapy mediated by methylene blue.

Photodermatol Photoimmunol Photomed 2020 Jul 6;36(4):308-312. Epub 2020 Apr 6.

Institute of Physical Chemistry Rocasolano, CSIC, Madrid, Spain.

Background: Although systemic therapies are recommended for severe or recalcitrant cases of pityriasis versicolor (PV), they are not free of important side effects and drug interactions. Photodynamic therapy (PDT) utilizes the action of singlet oxygen and free radicals produced by a light-activated photosensitizer to kill viruses, bacteria, or fungi. In this study, the effect of a PDT mediated by methylene blue (MB) in PV was evaluated. Read More
