摘要: Background: In this study, repeated measurements were made of levels mold spores, bacteria, and dust-mite allergens over a 7-month period in the homes asthmatics, relationships with measures asthma severity evaluated. Methods: A sample 57 asthmatic individuals, living 44 East Moline, Illinois, nearby communities, participated panel study. The visited up to nine times during study collect air dust samples. Asthma indicators derived from questionnaire data daily health records Associations between indoor tested several indicators. Results: There was evidence associations all total Gram-negative but mold-spore abundance associated only emergency room (ER) visits for asthma. No significant found house-dust-mite allergen any indicators, low, median concentrations 0.18 µg/g Der f 1 0.19 µg/g p 1. Conclusions: Some increased bacteria spores severity, particularly ER visits. association indicators; however, mite-allergen generally well below proposed threshold level 2 µg/g dust.
