ABSTRACT

Objective To investigate the breeding situations of acaroid mites in some dwellings in Zhangjiagang city and the influence on the patients with mites allergic asthma.Methods Acaroid mites in the dust from five different positions of rooms of 40 patients with mites allergic asthma and 40 normal control were counted and identified by light microscope.Results The detection rate of acaroid mites in 400 samples was 52.25%(209/400).A total of 2 746 acaroid mites were detected,which belong to 15 species and 7 families.The highest breeding rate and relative abundance were 46.25%(185/209)and 54.26%(1 490/2 746)respectively,which comes from Pyroglyphidae family,the following families were Acaridae(34.5%;23.89%)and Glycyphagidae(19.25%;18.14%).About the breeding densities of acaroid mites,statistical difference between patients and normal control was found(P
