| [comparative analysis of radial linear growth velocity of micromycetes isolated from different ecotopes]. | the work aim was the discovering of peculiarities of microscopic fungi responding to radioactive pollution by growth velocity change. the linear growth velocity of a broad range of micromycetes was analyzed. they were chosen in such a way that every species, as far as possible, was presented by the strains isolated from radioactive polluted and clean regions. most of the studied species were characterized by the absence of reliable growth velocity differences of strains of the same species growi ... | 2002 | 12190032 |
| morphology and phylogenetic placement of endoconidioma, a new endoconidial genus from trembling aspen. | endoconidioma populi gen. et sp. nov. is described from black subicula on twigs of trembling aspen, populus tremuloides, in alberta, canada. pycnidium-like conidiomata are produced on twigs and in culture, but, unlike pycnidia, conidiomata of e. populi have a closed peridium and a locule filled with conidiogenous cells that form conidia endogenously. these endoconidia are hyaline, unicellular and released by the dissolution of the peridial cell wall. in addition to endoconidia, mostly two-celled ... | 2004 | 21148931 |
| intraspecific variability and exopolysaccharide production in aureobasidium pullulans. | forty seven strains of the black yeasts, aureobasidium pullulans and hormonema dematioides, and the type strain of hormonema macrosporum were examined using pcr-ribotyping and universally primed pcr with subsequent hybridization. four groups (populations) were distinguished within a. pullulans with pcr-ribotyping, which largely coincided with up-pcr/hybridization groups. the up-pcr technique revealed a greater degree of heterogeneity between the groups studied. five strains identified as hormone ... | 1995 | 8526482 |
| cutaneous phaeohyphomycosis caused by a rare fungal pathogen, hormonema dematioides: successful treatment with ketoconazole. | annular, fungating, ulcerated lesions developed on both hands of a 64-year-old immunocompetent man 2 months after he was cut with barbed wire. a dematiaceous mold, hormonema dematioides, heretofore not definitively associated with human disease, was grown from two separate tissue specimens during a period of 9 days. histopathologic examination demonstrated rare small, periodic acid-schiff-positive, hyaline, yeastlike organisms in tissue. twelve weeks of empiric therapy with ketoconazole, 400 mg/ ... | 1990 | 2394856 |
| sydowia polyspora associated with current season needle necrosis (csnn) on true fir (abies spp.). | current season needle necrosis (csnn) has been a serious foliage disorder on true fir christmas trees and bough material in europe and north america for more than 25y. approximately 2-4 weeks after bud break, needles develop chlorotic spots or bands that later turn necrotic. the symptoms have been observed on noble fir (abies procera), nordmann fir (a. nordmanniana) and grand fir (a. grandis) on both continents. csnn was reported as a physiological disorder with unknown aetiology from usa, denma ... | 2010 | 20943166 |
| phenotypic and genotypic diversity among strains of aureobasidium pullulans in comparison with related species. | intra-specific diversity of 200 aureobasidium pullulans strains isolated from different sources and their relatives kabatiella lini cbs 125.21 t and hormonema prunorum cbs 933.72 t were studied by assessment of macromorphological, and physiological tests, sodium dodecyl sulfate-polyacrylamide gel electrophoresis technique (sds-page) of whole-cell proteins as well as enterobacterial repetitive intergenic consensus (eric)-, repetitive extragenic palindromic (rep)- and box-pcr techniques (collectiv ... | 2009 | 19123008 |
