INTRODUCTION Agricultural producers are exposed to a number of different health risks associated with their work environment. AIM The objective of the study was to assess the degree of colonization by fungi in terms of quantity and in terms of variety of species the samples taken from the settled dust from combine threshing of rye cultivation from organic and conventional farms in the Provinc...

ABSTRACT Alternaria isolates were obtained from various pistachio tissues collected in five orchards in California. For all isolates, morphological characteristics of the colony and sporulation apparatus were determined and compared with those of representative isolates of A. alternata, A. tenuissima, A. arborescens, and A. infectoria. A selection of the pistachio isolates and the representativ...

Most studies on molds focus on Alternaria alternata and Aspergillus fumigatus. Here, we report on inflammatory and allergenic properties of more typical indoor species Aspergillus versicolor, P. chrysogenum, C. cladosporioïdes, and C. sphaerospermum that were compared to A. alternata and A. fumigatus. In a mouse model, after intranasal instillation, A. alternaria, A. versicolor, and C. sphaeros...

This work aimed to evaluate the chemical composition, yield, and antifungal activity of essential oils (EO) native species from ‘Campos de Cima da Serra’ region, South Brazil. The Aloysia gratissima, lycioides, Blepharocalyx salicifolius, Cunila angustifolia, Myrciaria delicatula, Myrcia brasiliensis, Ocimum sp., Schinus polygama had an EO yield higher than 0.1% v/m. in vitro these was tested o...

During the meteorologically contrasting period of 2003-2005, the contamination of winter wheat, malt barley and fodder barley grain with micromycetes during grain harvesting and preparation for storage was investigated. Micromycetes of over 70 species ascribed to 16 genera were isolated and identified, the density of their populations in grain was determined. Micromycetes with a population dens...

background: alternaria alternata (aa) is a fungus that has wide range of plant host and can cause diseases in humans and produces a number of mycotoxins. exposure to high numbers of aa spores can trigger severe asthma exacerbations. resistance to antifungal drug has been shown in this species. trachyspermum copticum (ajowan) is an annual herbaceous essential oil )eo) bearing plant . the ripenin...

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...

Eight fungal species characterized by chitinolytic activity were isolated from Egyptian black sand collected from Rosetta coast. Genus Aspergillus and Alternaria alternata exhibited the highest density (> 40% of the total count, each) on the isolation plates containing different treatments of native shrimp shell chitin. Genus Aspergillus was represented by A. flavus, A. niger, A. foetidus and A...
