Abstract

The composition of mites present in house dust from houses of 35 people with respiratory allergy, such as bronchial asthma and allergic rhinitis, was investigated in 8 locations in the National Capital Region in the Philippines. Two methods of dust collection were used, namely: the floor sweep and the vacuum cleaner methods. The floor sweep method utilized a fine-brush broom and dustpan to sweep and collect 1 g dust samples from floor surfaces. The vacuum cleaner method used the Magic brush to collect 1 g of dust from surfaces of the following: 1) beddings (including bed sheets, blankets, pillows and mattresses), 2) upholstered furniture (including furniture that have cloth as covering) and 3) carpets (including all types of cloth or textile used as floor covering). All dust samples were brought to the laboratory for mechanical processing and mite species identification. Results revealed that the most predominant mites in house dust were Blomia tropicales and Dermatophagoides pteroryssinus. The houses sampled were also found to have Suidasia pontifica. Cheyletus malaccensis and an unidentified species of Glycyphagidae. Results showed that the major mites in houses of the respiratory allergic persons can be grouped into house dust mites and stored product mites.
