Sensitivity to fungi is a major risk factor for the development of asthma. However, the prevalence of fungal sensitivity in asthma is not completely understood. Nonetheless upward of 80% of asthmatic patients may be sensitized to one or more fungi. Fungal exposure occurs primarily from outdoors sources, but can occur in the indoor environment as well. Assessment of fungal exposure requires a mu...
OBJECTIVES Exposure to high levels of non-infectious microbial agents is recognised as a cause of respiratory disease in working populations, but except for endotoxins, little is known about exposure-response relations. As these effects do not depend on viability, exposure to non-viable microbial agents is important. Various methods not based on microbial cultures were explored to study the com...
The Bi-Air (BA) dual-trace 25 mm filter cassette was described, and its performance for the collection of Aspergillus/Penicillium (Asp/Pen) and Stachybotrys type spores in a clam-air settling chamber was compared to that of the Air-O-Cell (AOC) cassette. The BA produced duplicate sample traces, the sample traces were confined to two small, welldefined areas on the filter, and the small size of ...
A simple, inexpensive method for disrupting dormant fungal spores is described.
BACKGROUND Dispersal events between habitat patches in a landscape mosaic can structure ecological communities and influence the functioning of agrosystems. Here we investigated whether short-distance dispersal events between vineyard and forest patches shape foliar fungal communities. We hypothesized that these communities homogenize between habitats over the course of the growing season, part...
Nosocomial fungal infections are amongst the main causes of mortality in patients admitted to healthcare settings, especially in immunocompromised populations. The predominant pathogens include Candida spp., Aspergillus spp., Mucorales spp., and Fusarium spp. Nosocomial fungal infections are increasing due to the underlying factors in decades ahead. One of the predisposing factors i...
Exposure to fungi, particularly in water damaged indoor environments, has been thought to exacerbate a number of adverse health effects, ranging from subjective symptoms such as fatigue, cognitive difficulties or memory loss to more definable diseases such as allergy, asthma and hypersensitivity pneumonitis. Understanding the role of fungal exposure in these environments has been limited by met...
Fungal spores are known to cause allergic sensitization. Recent studies reported a strong association between asthma symptoms and thunderstorms that could be explained by an increase in airborne fungal spore concentrations. Just before and during thunderstorms the values of meteorological parameters rapidly change. Therefore, the goal of this study was to create a predictive model for hourly co...
