Malassezia polysorbatinonusus sp. nov., a Novel Isolate from a Japanese Patient with Seborrheic Dermatitis.

We describe a novel Malassezia species named Malassezia polysorbatinonusus, isolated from a Japanese patient with seborrheic dermatitis. The internal transcribed spacer (ITS) region of the isolate (LSEM 4845) were only 94.7% identical to those of M.

In vitro susceptibility testing of essential oils and their main components against antifungal-resistant Malassezia pachydermatis.

Canine Malassezia dermatitis (CMD) and otitis externa are generally treated by antifungal drugs. However, azole-resistant strains have been isolated from canine skin and ear canals worldwide. Phytochemicals isolated from essential oils are effective alternatives for inhibiting Malassezia pachydermatis.

A Mother and Daughter with Tinea Corporis Caused by Microsporum canis Apparently Transmitted from a Domestic Cat.

The patient was a girl (case 1) and her mother (case 2). The family had purchased a domestic cat five months previously. Three months later, both patients developed eruptions.

Genotyping and drug susceptibility profiling of Prototheca sp. strains isolated from cases of protothecosis in dogs.

Background: Protothecosis in dogs is a rare, yet emerging disease, distinguished by its often-aggressive clinical course and high fatality rate. Our study was conducted to enhance treatment protocols for affected dogs by better understanding the genetic diversity and drug resistance patterns of Prototheca species.

Objectives: To identify species and drug susceptibility profiles of an international collection of 28 Prototheca strains isolated from cases of protothecosis in dogs.
