Chromoblastomycosis caused by Exophiala spinifera.
We report the second case of chromoblastomycosis caused by Exophiala spinifera; this is the first known case in the United States. Examination of biopsied tissue showed thick-walled, internally septated, chestnut brown muriform cells (sclerotic bodies) within multinucleated giant cells present in the dermis that were characteristic of chromoblastomycosis. The individual cells within the murifor...
متن کاملNature and identification of Exophiala werneckii.
The morphological and physiological characteristics of 44 isolates of Exophiala werneckii recovered from human and environmental sources were indistinguishable from 2 isolates that caused tinea nigra. Casein hydrolysis and inability to decompose tyrosine differentiate E. werneckii from Exophiala jeanselmei, Exophiala spinifera, and Wangiella dermatitidis.
متن کاملExopolysaccharides and capsules in human pathogenic Exophiala species.
The black yeasts Exophiala spinifera and E. dermatitidis produce extracellular slimes, which may be either in the form of a well-delimited capsule or of diffusely exuded exopolysaccharides (EPS). The optimal conditions for their production were studied. The presence or absence of polysaccharide material can be used for recognition of the two species. Five-day-old cultures grown on potato glucos...
متن کاملMolecular Phylogenetics of Exophiala Species Isolated from Korea
BACKGROUND Recently, identification of fungi have been supplemented by molecular tools, such as ribosomal internal transcribed spacer (ITS) sequence analysis. According to these tools, morphological Exophiala species was newly introduced or redefined. OBJECTIVE This study was designed to investigate the phylogenetics based on ribosomal ITS sequence analysis from clinical Exophiala species iso...
متن کاملAntifungal therapies in murine disseminated phaeohyphomycoses caused by Exophiala species.
OBJECTIVES We have evaluated the efficacy of posaconazole, itraconazole and amphotericin B in murine models of disseminated infection caused by Exophiala spp. METHODS Immunosuppressed mice were treated with posaconazole at 10, 20 or 40 mg/kg/day orally (po), amphotericin B at 1.5 mg/kg/day intraperitoneally (ip) or itraconazole at 50 mg/kg/day po. Treatment began 1 day after infection and con...
