Bilobetin and 4'''-O-methylamentoflavone were isolated and identified in the needles of Taxus baccata, for the first time in this species. The antifungal activity of biflavones from T. baccata and Ginkgo biloba, namely amentoflavone, 7-O-methylamentoflavone, bilobetin, ginkgetin, sciadopitysin and 2,3-dihydrosciadopitysin towards the fungi Alternaria alternata, Fusarium culmorum, Cladosporium o...

Cladospofium resinae was grown in submerged cultures on glucose; on Jet-A commercial aviation fuel; and on a series of n-alkanes, n-decane through n-tetradecane. Cell yield was greatest on glucose and least on Jet-A; n-alkanes were intermediate. Among n-alkanes cell yield decreased as chain length increased, except for n-dodecane, which supported less growth than n-tridecane or n-tetradecane. T...

Seventeen taxa of dematiaceous fungi isolated from humans were tested to determine their responses to various concentrations of sodium chloride in vitro. Five groups of species were recognized on the basis of differing tolerances. Phaeoannellomyces werneckii was distinguished by its tolerance of greater than or equal to 15% NaCl; most dematiaceous pathogens were suppressed at less than or equal...

The vibration of fungal cultures was evaluated to determine its potential effect on the dispersal of airborne fungal microorganisms suspected of being pathogens. An artificial vibration system, which simulates the actual environmental vibration of fungal structures, was designed and constructed for this purpose. Experiments featured the use of low-frequency vibrations similar to those induced b...

The diversity of symbiotic fungi associated with the gorgonian coral Echinogorgia rebekka from the Weizhou coral reef in the South China Sea was investigated. Combined with morphologic traits, ITS-rDNA sequences revealed 18 fungal strains from this gorgonian. All of the 18 fungi belonged to the phylum Ascomycota and were distributed among seven genera in five orders: Eurotiales (Aspergillus and...

Mutagenesis was used to identify and characterize plant genes required for fungal disease resistance gene function in tomato. Seed of a stock homozygous for the Cf-9 gene for resistance to Cladosporium fulvum were treated with ethyl methanesulfonate, and 568 M2 families were screened for mutations to C. fulvum sensitivity. Eight mutants with reduced resistance were isolated. Four mutations, all...

BACKGROUND Mold is ubiquitous in our environment and is a common allergen in allergic diseases. The skin test and the Pharmacia ImmunoCAP system (CAP) for assay-specific immunoglobulin E (IgE) antibodies are both widely used. The goal of this study was to compare the performance of the skin test and CAP in the evaluation of mold allergy. METHODS Patients with allergic rhinitis were enrolled a...

The ability of an image analysis routine to differentiate between spores of eleven allergenic fungal genera was tested using analysis based on seven basic and up to 17 more complex features, extracted from digitised images. Fungal spores of Alternaria, Cladosporium, Fusarium, Aspergillus, Penicillium, Botrytis, Epicoccum, Exserohilum, Ustilago, Coprinus and Psilocybe were examined in a series o...

BACKGROUND Infectious crystalline keratopathy is a rare, progressive infection characterized by the insidious progression of branches and crystalline corneal opacities with minimal or no inflammation. This case report describes the evolution of an infectious crystalline keratopathy caused by Cladosporium sp., which developed after tectonic keratoplasty in a patient with a history of ocular trau...

Cladosporium chlorocephalum (= C. paeoniae) is a common, widespread leaf-spotting hyphomycete of peony (Paeonia spp.), characterised by having dimorphic conidiophores. During the season, one stage of this fungus causes distinct, necrotic leaf-blotch symptoms on living leaves of Paeonia spp. In late autumn, winter or after overwintering, a second morphologically distinct conidiophore type occurs...
