Onychomycosis caused by dematiaceous fungi: A four-year study among agricultural workers of Assam, India [PDF]

Current Medical Mycology, 2023
Background and Purpose: Onychomycosis due to dematiaceous fungi is rarely reported and the identification is also quite tricky due to poor sporulation.The recent emergence of dematiaceous fungi as a cause major of onychomycosis is a matter of concern in ...

The Distinction between Dematiaceous Molds and Non-Dematiaceous Fungi in Clinical and Spiked Samples Treated with Hydrogen Peroxide Using Direct Fluorescence Microscopy [PDF]

Journal of Fungi, 2023
Dematiaceous fungi are pigmented molds with a high content of melanin in their cell walls that can cause fatal infections in immunocompromised hosts. Direct microscopy is the main method for the rapid diagnosis of dematiaceous fungi in clinical specimens.

Novel aliphatic epoxide hydrolase activities from dematiaceous fungi [PDF]

FEMS Microbiology Letters, 1996
Epoxide hydrolases were found to be constitutively expressed in dematiaceous fungi coincident with secondary metabolite pigment production in stationary or idiophase. Washed-cell preparations of two fungi, Ulocladium atrum CMC 3280 and Zopfiella karachiensis CMC 3284, exhibited affinity for 2,2-dialkylated oxiranes, for which contrasting ...

Evaluation of proteolytic activity to differentiate some dematiaceous fungi [PDF]

Journal of Clinical Microbiology, 1988
A total of 123 isolates of Cladosporium spp., Exophiala spp., Fonsecaea spp., Lecythophora hoffmannii, Phaeoannellomyces werneckii, Phialophora spp., Wangiella dermatitidis, and Xylohypha bantiana were tested for proteolytic activity by using 26 different formulations of gelatin, milk, casein, and Loeffler media. Other physiological properties examined

Isolation of dematiaceous pathogenic fungi from a feed and seed warehouse [PDF]

Journal of Clinical Microbiology, 1982
In an epidemiological study, nine isolates of dematiaceous fungi were recovered from the interior of a local feed and seed warehouse. Sample sites include brick walls and floors. Air samples also were included. Samples were collected in saline and plated on Mycobiotic and Sabouraud agar.
