Abstract
Domestic mites, the combined group of household-living storage mites and pyroglyphid housedustmites, belong to subclass Acari. Identifying mites to species level help to improve the managementof their allergies as they produce species-specific allergens. Knowledge of the impact ofthe diverse and changing ecological conditions in the home environment is useful in developingstrategies to avoid the development and growth of large populations of domestic allergic mites.This study identified domestic mite’s species in six Egyptian Governorates. The dust sampleswere collected from the HDM allergic patients for identification and seasonal distribution. From120 samples, seven species were identified: Dermatophagoides farinae (69.4%), D. pteronyssinus(55.5%), Tyrophagus spp. (38.8%), Blomia tropicalis (30.5%), Cheyletus spp. (13.8%), Euroglyphusmaynei (5.5%), and Tarsonemus spp. (5.5%). The highest positive samples were in QalyobiaGovernorate (73.7%) and lowest in Cairo Governorate (33.3%). Highest number of miteswas in spring and autumn seasons, and D. farinae was the commonest one.
