Sputum Isolation of Wangiella dermatitidis in Patients with Cystic Fibrosis
Scandinavian Journal of Infectious Diseases, 2001 We report a case of invasive fungal pulmonary infection in a cystic fibrosis patient. Clinical deterioration coincided with isolation of Wangiella dermatitidis from her sputum, and treatment with amphotericin B followed by voriconazole resulted in clinical improvement and sterilization of the sputum. This case suggests that W.

Pleoanamorphic life cycle ofExophiala (Wangiella) dermatitidis
Antonie Van Leeuwenhoek, 1994The anamorph life cycle of the black yeast Exophiala (Wangiella) dermatitidis is described. The fungus is dimorphic, yeast cells being the prevalent form of propagation. The fungus is strongly hydrophilic, probably completing its anamorph life cycle in submersion. Adaptation to dry conditions is slow.

Thermotolerance of Wangiella dermatitidis
Journal of Clinical Microbiology, 1978A variety of diagnostic tests used by many laboratories to identify isolates of Wangiella dermatitidis (= Fonsecaea dermatitidis) were evaluated. Thirteeen isolates of W. dermatitidis were studied with respect to their ability to grow at 25, 37, 40, 45, and 50 degrees C, colonial and micromorphology, gelatin liquefaction, and hydrolysis of casein ...

Polymorphism of Wangiella dermatitidis
, 1985 Wangiella dermatitidis exhibits a polymorphism consisting of three well-defined morphologies, together with various forms characteristic of transitions among them (Figure 1). The organism may exist as moniliform or true hyphae, characterized by apical growth and production of blastoconidia.

Pathogenicity of Wangiella Dermatitidis
, 1993 Wangiella dermatitidis is a polymorphic dematiaceous human pathogen causing phaeohyphomycosis.2,5,12 The dark pigmentation associated with the majority of the dematiaceous fungi causing chromoblastomycosis and phaeohyphomycosis results from cell wall melanin which is synthesized via pentaketide metabolism and is termed DHN melanin.6–8,16 Wangiella ...

Pentaketide metabolites of melanin synthesis in the dematiaceous fungus Wangiella dermatitidis
Archives of Microbiology, 1984Melanin synthesis in the dematiaceous, polymorphic hyphomycete Wangiella dermatitidis, a human pathogen, was investigated by biochemical and physiological techniques. Mutants with a decrease or loss in melanin synthesis were induced and isolated.

Mycoses, 1986
Summary: Phaeohyphomycotic cyst developed on the little finger of the right hand of a 74‐year‐old man following a burn. The diagnosis was made by histopathologic examination of the excised cyst and by isolation of the causal agent in pure culture. The excised cyst walls contained large numbers of dematiaceous, fungal elements in the form of hyphae ...

The treatment of pulmonaryWangiella dermatitidisinfection with oral voriconazole
Journal of Clinical Pharmacy and Therapeutics, 2011Wangiella dermatitidis is a darkly pigmented fungus that has been isolated from the soil, dead plant material and areas of high humidity. Infection from the pathogen has not been extensively documented and few published cases report survival. Of the antifungal agents used in previous reports, none has been proven to improve outcomes.
