Temperature-sensitive multicellular mutants of Wangiella dermatitidis [PDF]
Three temperature-sensitive morphological mutants of Wangiella dermatitidis were isolated and characterized. The mutants grew in the yeastlike morphology at the permissive temperature (25 degrees C) but expressed a multicellular (Mc) phenotype at the restrictive temperature (37 degrees C). Cultures of Mc 2 and 3 incubated at the restrictive temperature

Exophiala (Wangiella) dermatitidis and cystic fibrosis – Prevalence and risk factors [PDF]
The objective of this prospective study was to assess the prevalence of Exophiala dermatitidis in respiratory secretions of patients with cystic fibrosis (CF) and to identify risk factors for its presence. The results of all cultures performed over a 2-year period in non lung-transplant patients in our CF clinic were included in the study.

Yeast-phase cell cycle of the polymorphic fungus Wangiella dermatitidis [PDF]
The yeast-phase cell cycle of Wangiella dermatitidis was studied using flow microfluorimetry and the deoxyribonucleic acid (DNA) synthesis inhibitor hydroxyurea (HU). Exposure of exponential-phase yeastlike cells to 0.1 M HU for 3 to 6 h resulted in the arrest of the cells in DNA synthesis and produced a nearly homogeneous population of unbudded cells.

Nuclear division in temperature-sensitive multicellular mutants of Wangiella dermatitidis [PDF]
Temperature-sensitive morphological mutants of Wangiella dermatitidis were stained with mithramycin, a fluorescent nuclear stain. Multicellular forms of the mutants each contained two or more nuclei, documenting that nuclear division accompanied the yeast-to-multicellular form conversion.

Comparative genomic and transcriptomic analysis of wangiella dermatitidis, a major cause of phaeohyphomycosis and a model black yeast human pathogen. [PDF]
Black or dark brown (phaeoid) fungi cause cutaneous, subcutaneous, and systemic infections in humans. Black fungi thrive in stressful conditions such as intense light, high radiation, and very low pH.

Molecular genetic studies of the model dematiaceous pathogen Wangiella dermatitidis
The rapidly improving molecular genetic tractability of Wangiella (Exophiala) dermatitidis significantly enhances its usefulness as a model for the more than 100 other dematiaceous (melanized) agents of human disease. Previously this model was based almost exclusively on its vegetative polymorphism, which at the simplest level is expressed as three ...

Central venous catheter-associated fungemia due to Wangiella dermatitidis.
Central venous catheter-related Wangiella dermatitidis infection has been increasingly reported in the recent literature. We report a case of central venous catheter (Port-A-Cath)-related fungemia caused by W. dermatitidis in a 58-year-old woman with lung cancer. Two W.
