In HIROSHIMA, one of the local cities, there is the tendency that detached houses are lately increasing just like other cities.We have conducted the investigation on the species (Dermatophagoides, Haplochthonlidas, Cosmochtonlidae, Tyrophagus putaescentiae, Cheyletidae, Tarsonemidae, Mesosligmata, others) and on the number of acarid existing in indoor dust of 16 detached houses, 8 houses of bronchial asthma group and 8 houses of the non-bronchial asthma group.The number of acarids was almost the same in both of bronchial asthma group and the non-bronchial asthma group throught out the year and many acarids were found in summer. Dermatophagoides was the species that was found most. 48124/m2/I week/4 seasons (Jan., Apr., Jul and Oct, ) of Dermatophagoides in the bronchial asthma group and 40114/m2l week/4 seasons (Jan., Apr., Jul. and Oct.) in the non-bronchial asthma group were found and it was found more in the bronchial asthma group in every season.It was about 5 times in summer against one in winter. Following orders are Tyrophagus putaescentiae, Haplochthonlidae and Tarsonemidae.Dermatophagoides was found at the rate of 93.84% on Jul. and 89.40% on Oct. in whole acarids.There was no correlation between the number of acarids and high RAST value group of Dermatophagoides peteronyssinum and Dermatophagoides farinae in the bronchial asthma group and the non-bronchial asthma group.The number of detached houses is increasing in local cities nowadays.Under these circumstances, the investigation on acarids in indoor dust showed that many Dermatophagoides were found in the bronchial asthma group and Dermatophagoides peteronyssinum·Dermatophagoides farinae RAST value of over 3 was 87.5%.
