Ninteen samples of dust from wool and carpet-weaving places around Tabriz were collected. Dust mites of wool and carpet-weaving places were separated and identified based on morphological characteristics. Genus and species of mites per gram of dusts, were determined. The results showed that dominant population of mites were: Dermatophagoides farinae (64%), Dermatophagoides pteronyssinus ( 21.5%), Euroglyphus maynei (8.5%) and 3 undistinguishable species of genus: Acarus , Chortoglyphus and Glycyphagus (6%). Clinical results showed that (44%) workers of to asthma had flowmetry lower than 85 FRV and most of them showed asthmatic clinical signs. Dermatophagoides mites were determined as the dominant mite population in wool and dusts of carpet weaving places and it seems to be an important allergen for inducing asthma in carpet weavers.
