| alternaria measures in inner-city, low-income housing by immunoassay and culture-based analysis. | sensitivity to alternaria allergens has been associated with severe asthma and life-threatening exacerbations, and a high prevalence of alternaria sensitivity has been reported among inner-city populations. traditionally, epidemiologic studies have measured indoor alternaria concentrations by cultural analyses; however, the number of viable spores may not be a good proxy for allergen levels. furthermore, other genera share epitopes with alternaria that may contribute to the allergenic effect. | 2008 | 18450123 |
| [contribution to the aeromycological study in the atmosphere of the city of granada (south of spain): seasonal and daily variations.]. | the seasonal and daily variations in the concentrations of certain fungal spores in the atmosphere of the city of granada (south of spain) have been studied. sampling was carried out in 1994 using a hirst-type volumetric spore trap. the spores analysed correspond to the genera alternaria, cladosporium (cladosporium cladosporioides and cladosporium herbarum), fusarium, stemphylium and ustilago. the seasonal-variation data obtained indicate that most of these spores are abundant throughout the yea ... | 1999 | 18473554 |
| effect of relative humidity and interrupted wetness periods on brown spot severity of pear caused by stemphylium vesicarium. | abstract field observations in four pear orchards during 5 years from april to october indicated that days with uninterrupted wetness of variable length represented 83.9% of the total days studied. however, days with surface wetness interruptions and with high relative humidity (rh) (>/=90%) without wetness occurred with a frequency of 7.1 and 6.2%, respectively. accordingly, the effect of interruption of 24-h wetness periods by dry periods of high or low rh on infections caused by stemphylium v ... | 2002 | 18944145 |
| purification and biological characterization of host-specific sv-toxins from stemphylium vesicarium causing brown spot of european pear. | abstract culture filtrates of a pathogenic isolate (it37) of stemphylium vesicarium, causing brown spot of european pear, induced veinal necrosis only on pear leaves susceptible to the pathogen. two host-specific toxins, sv-toxins i and ii, were purified from culture filtrates of it37 by successively using amberlite xad-2 resin adsorption, cellulose thin-layer chromatography, and high-performance liquid chromatography under three different sets of conditions. susceptible cultivars showed veinal ... | 1999 | 18944740 |
| fungal sensitivity to and enzymatic degradation of the phytoanticipin alpha-tomatine. | abstract alpha-tomatine, synthesized by lycopersicon and some solanum species, is toxic to a broad range of fungi, presumably because it binds to 3beta-hydroxy sterols in fungal membranes. several fungal pathogens of tomato have previously been shown to be tolerant of this glycoalkaloid and to possess enzymes thought to be involved in its detoxification. in the current study, 23 fungal strains were examined for their ability to degrade alpha-tomatine and for their sensitivity to this compound an ... | 1998 | 18944982 |
| the effects of meteorological factors on airborne fungal spore concentration in two areas differing in urbanisation level. | although fungal spores are an ever-present component of the atmosphere throughout the year, their concentration oscillates widely. this work aims to establish correlations between fungal spore concentrations in porto and amares and meteorological data. the seasonal distribution of fungal spores was studied continuously (2005-2007) using volumetric spore traps. to determine the effect of meteorological factors (temperature, relative humidity and rainfall) on spore concentration, the spearman rank ... | 2009 | 19048306 |

| molecular and morphological description of two new species of stemphylium from china and france. | two new species of stemphylium (anamorphic pleospora) are described on the basis of morphological characters and molecular phylogenetic analyses. stemphylium phaseolina and s. variabilis were isolated respectively from diseased leaves of phaseolus vulgaris l. in hebei province, china, and from diseased leaves of allium sativum l. in angres, france. the two species exhibit characteristic stemphylium morphology but are distinct from similar species based on the morphology and development of conidi ... | 2010 | 20524602 |
| a thaumatin-like gene from asparagus officinalis (aoprt-l) exhibits slow activation following tissue maceration or salicylic acid treatment, suggesting convergent defence-related signalling in monocots. | summary messenger rna derived from mechanically separated cells of asparagus has proved to be an enriched source of defence-related transcripts. we describe the characterization of a novel pr-5 gene coding for a secreted protein of neutral pi (aoprt-l) that is strongly up-regulated following cell isolation or following accelerated tissue ageing caused by tissue maceration, but which is also responsive to salicylic acid, a defence-related signal not normally associated with wound responses. infec ... | 2000 | 20572983 |
| molecular characterization of embellisia and nimbya species and their relationship to alternaria, ulocladium and stemphylium. | dna sequences from rdna and protein-coding regions were determined for six embellisia and two nimbya spp. and were compared to those from alternaria, ulocladium and stemphylium spp. sequences determined included rdna from the nuclear internal transcribed-spacer region (its1/5.8s/its2) and the mitochondrial small-subunit (mt ssu) and a portion of the glyceraldehyde-3-phosphate dehydrogenase (gpd) gene. phylogenetic analyses were performed on each dataset separately and then combined for total evi ... | 2003 | 21149017 |
| phylogeny of stemphylium spp. based on its and glyceraldehyde-3-phosphate dehydrogenase gene sequences. | the phylogenetic relationships among 44 isolates representing 16 species of stemphylium were inferred from its and glyceraldehyde-3-phosphate dehydrogenase (gpd) sequence data. the results generally agree with morphological species concepts. there was strong support for monophyly of the genus stemphylium. analysis of the gpd fragment in particular was useful for establishing well-supported relationships among the species and isolates of stemphylium. species of stemphylium that appear to have los ... | 2002 | 21156539 |
| sinomyces: a new genus of anamorphic pleosporaceae. | sinomyces gen. nov. is described for ulocladium alternariae and two new species from china. these three species differ from ulocladium in producing simple conidiophores with a single, cicatrized apical pore or 1 or 2 short, uniperforate, geniculate sympodial proliferations. phylogenetic analysis of partial dna sequences of the glyceraldehyde-3-phosphate dehydrogenase gene (gpd) gene and a fragment of the alternaria alternata major allergen (alt a 1) gene, using maximum-parsimony (mp), maximum-li ... | 2010 | 21315316 |
| fungal spores from pleosporales in the atmosphere of urban and rural locations in portugal. | fungal spores are a significant fraction of the atmospheric bioparticles (bioaerosols) and many species are capable of inducing the production of specific immunoglobulin e (ige), aggravating the clinical symptoms of allergic respiratory diseases in sensitized individuals. the aim of this work was to evaluate the distribution of potentially allergenic pleosporales spores in two locations with different urbanization indexes, characterizing its seasonal pattern. the seasonal distribution of several ... | 2010 | 21491687 |
| identification of allergens homologous to alt a 1 from stemphylium botryosum and ulocladium botrytis. | several studies have demonstrated that proteins homologous to the alt a 1 major allergen of alternaria alternata are expressed in other members of the pleosporaceae family. however, since no direct biochemical data have been reported concerning the presence of alt a 1 allergen homologues capable of binding ige in the excretion-secretion products of stemphylium and ulocladium, our objective was to explore their presence in stemphylium botryosum and ulocladium botrytis. s. botryosum and u. botryti ... | 2011 | 21504377 |
