| Abstract: | This study was designed to determine the occurrence, distribution and abundance of house dust mites (HDM) in residential homes
in Bandar Abbas (Hormozgan Province), because of numerous complaints of allergies in this oriental city. The study area was
divided in five sampling zones based on population density and geographical distribution. In each sampling zone 10 houses
were randomly selected. A total of 50 home dust samples were collected using a portable vacuum cleaner for 2 min from 1 m2 of the surface of mattresses, carpets, sofas and furniture in residential houses. After collection, samples were immediately
frozen. Mite species were identified and counted using standard methods and keys. Of the sampled houses 88% (44 houses) were
contaminated with at least one HDM species. Three species were identified: Dermatophagoides pteronyssinus (63.1%), D. farinae (32.8%) and D. evansi (4.1%) (Pyroglyphidae). Our findings indicate a relationship between HDM density and moisture and temperature of residential
places. The high contamination rate of residential houses (88%) and the favourable environmental conditions for these arthropods
stress that they should be considered as important allergic causing agents. |
