RESUMO

House dust mites (HOM) have been considered the major source of allergens in dwellings, being mattresses and pillows the most important reservoirs. This work studied the mite fauna of upper and lower faces of 57 mattress from the city of Campinas, state of São Paulo, Brazil. Also, it was studied the HOM immediate Sensitivity in 124 atopic patients, using B.U. standardized extracts for Dermatophagoides pteronyssinus, Dermatophagoides farinae and Blomia tropicalis. Ali dust samples was collected by a vacuum cleaner and the samples was studied for mites through an optic microscopic. The results showed a skin positivity of 72.6% for D. farinae, 66.9% for D. pteronyssinus and 47.4% for B. tropicalis. As for mite fauna, it was found an increase over 3.5 at the lower face of the mattresses, when compared with the upper face, showing a mean number of 932 mites/gram of fine dust at upper face and 3,254 mites/g at lower face. The major family observed in both mattress faces was Pyroglyphidae, being D. pteronyssinus the most frequent species found. TarsQ nemidae family was the second more frequent mite family observed at upper faces and Glycyphagidae family was the second one at the lower face. There was a significative difference between the number of mites found at the two mattress faces for the families Pyrogliphidae, Glycyphagidae, Acaridae and other families . Foam mattress was the most frequent (86.2%) mattress and mattress-covers was related only by 10.3% of volunteers
