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 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...

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 ...

A case study on extensive fungal growth that occurred in an apartment building after firefighting efforts is described in this paper. Exposure to airborne microorganisms (both viable and total) was investigated by filter sampling in three periods before and during remedial actions after the fire. Material samples were also analyzed. Extensive mold growth was observed on the building materials a...

BACKGROUND Children living in a damp house are more likely to suffer from respiratory symptoms and it has been suggested that exposure to fungi is an important contributing factor. However, more knowledge about underlying mechanisms for the association are needed. OBJECTIVE To identify associations between measures of house dampness, levels of airborne fungal spores, housing factors and healt...

Airborne fungal spores are an important fraction of atmospheric particulate matter and are major causative agents of allergenic and infectious diseases. Predicting the variability and species of allergy-causing fungal spores requires detailed and reliable methods for identification and quantification. There are diverse methods for their detection in the atmosphere and in the indoor environments...

Hospital construction and renovation activities are an ever-constant phenomenon in healthcare facilities, causing dust contamination and possible dispersal of fungal spores. We reviewed fungal outbreaks that occurred during construction and renovation over the last 4 decades as well as current infection prevention strategies and control measures. Fungal outbreaks still occur in healthcare setti...
