Inhalation of fungal spores has been shown to cause primary or secondary infection and respiratory inflammation and diseases such as allergic alveolitis, atopic asthma, and organic dust toxic syndrome, which are rarely reported in the absence of predisposing factors. Biochemical and molecular markers of inflammation were measured in rat bronchial alveolar lavage cells (> 95% macrophages) follow...

J. Econ.Entomol.91(3): 624-630 (1998) ABSTRACT Evaluations of the efficacy and persistence of Beauveria bassiana (Balsamo) Vuillemin for control of the diamondback moth, Plutella xylostella (L.),on cnlcifers were done in growth chambers, the greenhouse, and the field. In growth chamber studies done at 21 or 26°C and 60 or 90%RH, neither temperature nor humidity affected the survival oflarvae, b...

The effects of the climatic changes more and more frequently, favour the emergence and the development of plant diseases. Botrytis cinerea and Oidium spp. spores are often responsible for enormous productivity losses in cultures with high commercial interests such as the grapevine. This work aims to detect these airborne spores, before the emergence of lesions in Vitis vinifera. In the rural ar...

The aim of this paper was to understand whether the endobacterium identified as Candidatus Glomeribacter gigasporarum has an effect on the biology of its host, the arbuscular mycorrhizal fungus Gigaspora margarita, through the study of the modifications induced on the fungal proteome and lipid profile. The availability of G. margarita cured spores (i.e. spores that do not contain bacteria), rep...

Parasites can cause extensive damage to animal societies in which many related individuals frequently interact. In response, social animals have evolved diverse individual and collective defences. Here, we measured the expression and efficiency of self-grooming and allo-grooming when workers of the ant Formica selysi were contaminated with spores of the fungal entomopathogen Metarhizium anisopl...

The aim of this work was to detect the presence of Basidiomycetes spores (basidiospores, teliospores, uredospores and aeciospores) in Mérida (SW Spain) and assess the influence of weather parameters. Air was sampled continuously with a volumetric seven-day Burkard spore trap for two years. Fungi spores were identified and counted at x1,000 microscope resolution. Daily and weekly meteorological ...

389 Exposure and sensitization to allergens can promote development and exacerbation of allergic disease. Various indoor aller-gens, including dust mites, animal dander, and mold have been reported to associate with allergic disease. Fungal spores and particles are widely distributed in outdoor and indoor environments and exposure to fungi has been shown to induce allergic disease and exacerbat...

The present study was aimed to design a simple model to check efficacy of germicidal UV tube, to standardise the position, distance and time for UV light and also to find out its efficacy against medically important bacteria, the bacterial spores and fungi. The microbial cultures tested included gram positive and gram negative bacteria, bacterial spores and fungal spores. The microbes streaked ...

OBJECTIVES The aim of this study was to extensively characterize grain workers' personal exposure during work in Norwegian grain elevators and compound feed mills, to identify differences in exposures between the workplaces and seasons, and to study the correlations between different microbial components. METHODS Samples of airborne dust (n = 166) were collected by full-shift personal samplin...
