Diversity, Distribution, and Abundance of House Dust Mites on Settlement Region in Bogor

摘要

The house dust mite (HDM) is a major allergen source and a significant cause of allergic rhinitis and allergic asthma. HDM is commonly found in dust originating from human resident and are mainly found in seats (chairs, sofas, benches), carpets, floors and beds (mattresses, pillows, sheets). This study was conducted on six types of settlements in Bogor, i.e. densely populated residential, residential complexes, guest houses, boarding schools, boarding houses and student dormitories. Dust from all the settlements collected by vacuum cleaner and HDM were then isolated and identified under microscope at laboratory. The result showed there were 10 types of HDM, i.e Blomia tropicalis (45.34%), Dermatophagoides pteronyssinus (17.45%), Cheyletidae (15.62%), Blomia spp. (8.61%), Mesostigmata (7.17%), Dermatophagoides farinae (3.67%), Oribatida (0.56%), Acaridae (0.32%), Tyrophagus spp. (0.16%), Lepidoglipus destructor (0.08%). The highest density of HDM on housing was found on the carpet, (23.94%) in densely populated residential and (33.71%) in residential complex. HDM mostly found on the furniture at guest houses (100%), boarding schools (37.62%), boarding houses (52.02%) and student dormitories (35.17%). There was significantly correlation between humidity and temperatures against the infestation of HDM in all types of settlements.
