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.

Importance of calcium to the regulation of polymorphism inWangiella (Exophiala) dermatitidis [PDF]
Critical steps implicated in the polymorphism of Wangiella dermatitidis were found to be sensitive to calcium ion availability. When grown in a defined, synthetic medium under various pH and temperature conditions, two thresholds of calcium ion concentrations were identified: a lower concentration favouring non-polarized growth leading to multicellular

Roles of the pH signaling transcription factor PacC in Wangiella (Exophiala) dermatitidis [PDF]
To study the function of the PacC transcription factor in Wangiella dermatitidis, a black, polymorphic fungal pathogen of humans with yeast-phase predominance, the PACC gene was cloned, sequenced, disrupted and expressed. Three zinc finger DNA-binding motifs were found at the N-terminus, and a signaling protease cleavage site at the C-terminus.

Systemic Phaeohyphomycosis due to Exophiala (Wangiella) in an Immunocompetent Child
We report a rare case of systemic lymphadenitis and hepatic involvement due to Exophiala (Wangiella) dermatitidis in a pediatric patient. An 8-year-old immunocompetent boy with chronic fever was examined through the use of sonography and CT scan which ...

WdChs5p of Wangiella (Exophiala) dermatitidis, a class V chitin synthase, is essential for sustained cell growth at temperature of infection [PDF]
The chitin synthase structural gene, WdCHS5 was isolated from Wangiella dermatitidis. Sequence analysis revealed that this gene has a myosin motor-like-encoding region at its 5′-end and a chitin synthase (class V)-encoding region at its 3′-end.
