Abstract
Dust mites are a medically important group of animals commonly found in carpets and mattresses in houses. Antigens in their feces cause allergic reactions such as asthma and contact dermatitis. Dust samples were vacuum-collected in a special collecting bag from a one square meter area from living room floors of 100 randomly sampled houses in Los Baños, Lagunafor one minute.Chromato-immunoassay ELISA (Mitey Checker) was used to detect mite antigenicity. Twenty-three species of mites were identified belonging to seven families. Of these, Blomiatropicalis(265 mites/g. of dust in 87% of households)of Family GlycyphagidaeandDermatophagoidesfarinae(71 mites/g. of dust in 58% of households)of Family Pyroglyphidae were the most prevalent and abundant species. Forty-eight percent (48%) of households were detected to have low levels of antigen (≤5μg/m2
). There was a weak linear relationship between mean total mite intensityand antigen levels (r= 0.129). MeanDermatophagoides intensity and antigen levels were also found to have a weak linear relationship.More mites were found in carpeted living rooms (822 mites/g) when compared to non-carpeted living rooms (645 mites/g). Different floor types did not show any difference in mean mite intensity.Likewise, mite intensity did not show correlation with household size.
