nature and identification of exophiala werneckii.the morphological and physiological characteristics of 44 isolates of exophiala werneckii recovered from human and environmental sources were indistinguishable from 2 isolates that caused tinea nigra. casein hydrolysis and inability to decompose tyrosine differentiate e. werneckii from exophiala jeanselmei, exophiala spinifera, and wangiella dermatitidis.19827153351
isolation of dematiaceous pathogenic fungi from a feed and seed warehouse.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. the nine dematiaceous fungi recovered from these samples were identified with microscopic morphology, thermotolerance, biochemical reactions, and animal virulence test. four isolates were identified as nonpathog ...19827200100
chromohyphomycosis of the hand due to exophiala jeanselmei (phialophora jeanselmei, phialophora gougerotii)--case report and review.a case of an unusual cause of chromomycosis of the hand is described. follow-up at 2 months revealed a complete recovery following removal of the mass, without treatment with antifungal therapy. a review of the different disease entities of the chromomycoses and a brief generic classification of the dematiacious fungi are presented.19817252112
porcine abortions associated with fungi, actinomycetes, and rhodococcus sp.history, lesions, and results of microbiologic examinations are given for four porcine abortions associated with fungi and one each associated with actinomadura madurae, an aerobic actinomycete, and rhodococcus sp. the fungi were gliomastix sp., petriellidium boydii, aspergillus fumigatus, and exophiala jeanselmei. parvovirus, isolated from one fetus, was the only other infectious agent identified. the presence of fungi, actinomadura madurae, and rhodococcus sp. in fetal and placental lesions in ...19817281459
serological cross-reactivity between sporothrix schenckii and various unrelated fungi.the serological cross-reactivity of sporothrix schenckii with various unrelated fungi was investigated by use of immunodiffusion tests. a rabbit anti s. schenckii serum was obtained, which reacted with cladosporium werneckii, c. carrionii, c. bantianum, coccidioides immitis, phialophora jeanselmei, p. gougerotii, p. dermatitidis, fonsecaea pedrosoi, aspergillus fumigatus, histoplasma capsulatum and trichophyton mentagrophytes, but not with saccharomyces cerevisiae antigens. the serological deter ...19816163987
misdiagnosis caused by fungal contaminant in a histological stain solution.silver stains on tissue and cytology specimens are important in the evaluation of patients with suspected fungal infections. care must be taken, however, to prevent misinterpretation of contamination artifacts. two cases presenting such a problem are reported. the first patient had granulomatous leg lesions that microscopically showed characteristics of erythema induratum but with budding yeastlike organisms demonstrated by grocott methenamine silver stain. cultures and subsequent biopsies were ...19806153661
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 ...19807189579
