We hereby present a rare case of fungal prosthetic valve endocarditis (PVE) and ascending aortic root graft infection in an immunocompetent host caused by dematiaceous
(18) However, mass spectra of dematiaceous
molds had fewer peaks, and spectrum quality was often not sufficient to create reference entries, suggesting that sample preparation for these fungi is more difficult.
fungus used in this study is brownish black in color, that is, belonging to the dematiaceous
The pus samples collected from superficial wounds, like burn wounds and bed sores, showed mainly the growth of Candida, whereas the sample collected from deep wounds or sinuses mostly showed filamentous fungi belonging to the dematiaceous
fungi/pigmented fungi constitute a clinically important group of fungi.
Interestingly, melanin pigments produced by fungi (dematiaceous
fungi, Cryptococcus spp, Aspergillus spp, Candida spp, Penicillium spp, among others) have a role in the survival and virulence of these organisms by interfering with the host immune phagocytic mechanisms (Figure 5, I).
Pathologic examination demonstrated abundant necrotic material containing septate hyphae fungal elements of brown pigment, consistent with a dematiaceous
Bipolaris is a genus of dematiaceous
hyphomycetes with more than 100 species .
