Dematiaceous fungal pathogens isolated from nature.


This study was conducted to demonstrate the presence of pathogenic dematiaceous fungi in nature. Using hamster and mouse inoculation techniques, 43 isolates of dematiaceous fungi were recovered from 39 samples of woody plant material and soil from the Virginia environment. Thirteen species were identified and included 4 Phialophora spp., 3 Cladosporium spp., 2 Exophiala spp., Sporothrix sp., Wangiella dermatitidis, Bispora betulina, and Scytalidium lignicola. Evidence is presented for the first isolations of C. trichoides from nature in the United States; these isolates proved to be pathogenic for mice in which they produced disease and death in a course similar to that seen in man. Natural isolates of Phialophora verrucosa, Phialophora repens, Exophiala jeanselmei, and Wangiella dermatitidis were identical to those species isolated from man using the following criteria: morphology, 12% gelatin reaction, and survival in laboratory animals.
