Airborne Endotoxin and -D-glucan in PM1 in Agricultural and Home Environments
Objectives: Concentrations of microbial cell wall components such as endotoxin and -D-glucan in airborne submicrometer particle size fraction (PM1, defined as particles with median aerodynamic diameter, da 1 m) have not been well characterized. In this study, airborne concentrations of endotoxin and -D-glucan among different size fractions were quantified in two distinctly different environment...
متن کاملAirborne microorganisms, endotoxin, and (1→3)-β-D-glucan exposure in greenhouses and assessment of respiratory symptoms among workers.
OBJECTIVES Greenhouse operations are an important sector of the horticulture industry, also known as the Green Industry. The objectives of this study were (i) to investigate exposure levels to airborne culturable fungi, bacteria (total culturable bacteria and actinomycetes), endotoxin, and (1→3)-β-D-glucan in three Midwest greenhouses during summer and winter using multiple exposure assessment ...

Predictors of airborne endotoxin in the home.
We identified home characteristics associated with the level of airborne endotoxin in 111 Boston-area homes enrolled in a cohort study of home exposures and childhood asthma, and we developed a predictive model to estimate airborne endotoxin. We measured endotoxin in family-room air and in dust from the baby's bed, family room, bedroom, and kitchen floor. Level of airborne endotoxin was weakly ...
متن کاملInvestigations of the relationship betw een disease and airborne (1→3)-β-D-glucan in buildings
Studies on the relationship between symptoms in indoor air and the amount of airborne (1-->3)-beta-D-glucan were reviewed. Relationships were found for symptoms and objective tests of airways inflammation. The data suggest that (1-->3)-beta-D-glucan could be a causative agent.
