BACKGROUND: Mite allergens have been involved in airway sensitization and @entity56 . Immunoassays for the identification and quantifiction of @entity6711 ( @entity6711 ) allergens are useful to improve the knowledge of regional mite fauna and the remediation of mite allergens in @entity56 . The present study analyzed the association between levels of @entity6711 allergen and results of mite identification or skin prick test (SPT) in two different areas of Bahia, Brazil. METHODS: Forty-two @entity748 subjects from a rural area (group I; n = 21) and a slum (group II; n = 21) were evaluated through SPT with @entity6711 allergens and had dust samples collected at their homes for mite identification and allergen measurements. RESULTS: Positive SPT to @entity7130 , @entity8786 and Blomia tropicalis allergens were observed in 42.9, 38.0 and 42.9% subjects from group I and in 47.6, 19.0 and 33.3% subjects from group II, respectively. @entity7130 and B. tropicalis were identified in approximately 76 and 50% of samples from both groups, respectively. @entity8786 was identified in 38.0 and 9.5% of samples from groups I and II, respectively (p < 0.005). Der p 1, Der f 1 and Blo t 5 detection were associated with mite identification (p < 0.05). Association between @entity6711 allergen levels over 2 microg/g of dust and positive SPT occurred only with @entity7130 (p < 0.0001). CONCLUSIONS: @entity7130 was the most prevalent mite species in this study followed by B. tropicalis and @entity8786 . Immunoassays done to measure mite allergens were associated with mite-species identification. We conclude that these three mite species must be included on panels for the diagnosis of allergic @entity1030 in subjects living in such regions.
