Eosinophils and their products are probably important in the pathophysiology of allergic diseases, such as bronchial asthma, and in host immunity to certain organisms. An association between environmental fungal exposure and asthma has been long recognized clinically. Although products of microorganisms (e.g., lipopolysaccharides) directly activate certain inflammatory cells (e.g., macrophages)...

The aim of this study was to monitor the mycobiota of wine grapes, occurrence of ochratoxigenic microfungi in wine grapes and occurrence of ochratoxin A and Alternaria mycotoxins in fresh grape juice, must and wine from domestic crops in the year 2004. Thirteen samples of wine grapes (white /nine samples/ and red /four samples/) were collected during harvesting in the Znojmo wine region, SE Mor...

Rabea E.I., Steurbaut W. (2010): Chemically modified chitosans as antimicrobial agents against some plant pathogenic bacteria and fungi. Plant Protect. Sci., 46: 149–158. The antimicrobial activity of eight chemically modified chitosans against plant pathogenic bacteria of crown gall disease agrobacterium tumefaciens and soft mould disease Erwinia carotovora and fungi of early blight disease al...

The two chitinase genes, LbCHI31 and LbCHI32 from Limonium bicolor, were, respectively, expressed in Escherichia coli BL21 strain. The intracellular recombinant chitinases, inrCHI31 and inrCHI32, and the extracellular exrCHI31 and exrCHI32 could be produced into E. coli. The exrCHI31 and exrCHI32 can be secreted into extracellular medium. The optimal reaction condition for inrCHI31 was 5 mmol/L...

Effect of aqueous leaf extracts of 8 allelopathic tree species viz., Accacia nilotica (L.) Willd ex Del., Alstonia scholaris (L.) R. Br., Azadirachta indica (L.) A. Juss., Eucalyptus citriodora Hook, Ficus bengalensis L., Mangifera indica L., Melia azedarach L. and Syzygium cumini (L.) Skeels was studied on germination and seed-borne mycoflora of wheat (Triticum aestivum L.). Wheat seeds were s...

Alternariol and alternariol monomethyl ether are commonly associated with weathered grain sorghum. Production of these metabolites and altenuene by isolates of Alternaria alternata was evaluated on various sterile grain substrates. At 35% moisture content and 25 C, metabolite yields were highest on rice, intermediate on sorghums, and lowest on wheat and yellow corn. Fourteen-to 21-day cultures ...

Abstract In order to explore the effects of arginine (Arg) treatment on postharvest rot jujube caused by Alternaria alternata (A. alternata), winter was treated with different concentrations Arg (0, 20, 200, and 1000 μmol/L). Results showed that substantially inhibited expansion lesion diameter, jujubes 200 μmol/L had smallest diameter. vitro experiments demonstrated could not inhibit spore ger...

Rare molds are increasingly emerging as a cause of deep and invasive fungal infections. We report here a rare case of cutaneous phaeohyphomycosis of the lower limbs due to Alternaria alternata associated with extra-ungual localization of Scopulariopsis brevicaulis. Diagnosis was made based on repeated, direct, microscopic mycological and histological examinations. The study revealed hyphae and ...

In this study honeys of Acacia modesta, Prunus persica, Zizyphus sativa and Isodon rogosus plants were tested against two Gram-positive bacterial strains (Staphylococcus aureus and Bacillus cereus), two Gram-negative bacterial strains (Klebsilla pneumonia and Escherichia coli) and two fungal strains (Alternaria alternata and Trichoderma harzianum) through Agar well diffusion method. The tested ...

New series of benzophenone imines with general formula Ph2-C=NR; R = Benzyl, 4-Fluorobenzyl, Naphthyl, Phenyl, 4-Nitrophenyl were synthesized by condensation of dichlorodiphenylmethane and different aromatic primary amines (1:1) Those imines were characterized by different physiochemical and spectroscopic techniques like melting point, elemental analysis, FT-IR, multinuclear NMR (H, C). After c...
