| systemic exophiala jeanselmei infection in a cat. | a 14-year-old spayed domestic shorthair cat was referred for ultrasonographic evaluation of abnormally shaped kidneys. multifocal lesions were detected ultrasonographically in the liver and kidneys; a fine-needle aspirate of the kidneys was performed, and numerous clumps of fungal hyphae were identified. the following day, the cat was recumbent with advanced neurologic signs. the cat was euthanatized, and a necropsy was performed. multifocal granuloma-like masses were seen on the liver, kidneys, ... | 2000 | 11132892 |
| nosocomial fungemia due to exophiala jeanselmei var. jeanselmei and a rhinocladiella species: newly described causes of bloodstream infection. | fungi have become increasingly important causes of nosocomial bloodstream infections. the major cause of nosocomial fungemia has been candida spp, but increasingly molds and other yeasts have caused disease. exophiala jeanselmei and members of the genus rhinocladiella are dematiaceous moulds, which have been infrequently associated with systemic infection and have not been described as causes of fungemia. in this paper, the occurrence of 23 cases of fungemia due to these organisms over a 10-mont ... | 2001 | 11158099 |

| sample preparation and 2-de procedure for protein expression profiling of black microcolonial fungi. | the ecology and stress adaptation of black rock inhabiting fungi in hot and cold extreme environments are not yet well understood. two-dimensional gel electrophoresis (2-de) is a promising tool to study the protein expression profiling and the metabolic status of microorganisms under stress conditions. the sample preparation has been shown to be the bottleneck for high resolution protein separation in 2-de. for this purpose conditions must be optimized to obtain reliable and reproducible results ... | 2011 | 21944209 |
| phaeohyphomycosis due to exophiala xenobiotica as a cause of fungal arthritis in an hiv-infected patient. | black yeasts including exophiala species are increasingly recognized as agents of human disease. in recent years, progress in molecular phylogeny and taxonomy of the genus exophiala has led to the description of numerous novel species. the 'classical' but highly variable species exophiala jeanselmei was split into a number of morphological siblings, which, however, were phylogenetically and clinically remote from each other. e. jeanselmei was restricted to an uncommon species causing subcutaneou ... | 2012 | 22217212 |
