L. de  aEvaluation of the concentration of allergens from mites in fur and households dust of dogs with atopic dermatitis.  c2017  aThis study evaluated the concentration of Der p 1, Der f 1 and Blo t 5 in the fur and households of 20 dogs with atopic dermatitis (AD) and 20 healthy dogs. The diagnosis of AD was clinical based on Favrot?s criteria. Dust samples were collected with a domestic vacuum cleaner. For each site, 1m2 was vacuumed for 2 min. The samples were collected in separate filters, transferred into plastic containers, sealed and kept frozen until ELISA analysis. In the fur of atopic dogs the average concentration of Der p 1 was 0.25?g/g compared to 0.03?g/g in healthy dogs. In households with atopic dogs the highest concentrations of Der p 1 were found in carpets (2.18?g/g), followed by couches (1.53?g/g), beds (1.14?g/g), dogs? bed linen (0.64?g/g) and floors (0.14?g/g). The concentrations of Der p 1 on carpets, couches and beds were significantly higher than in atopic dogs? fur (p&lt0.05). There was no statistical difference when comparing the concentrations of Der f 1 and Blo t 5 in different environments of atopic dogs (p&gt0.05). The concentrations of Der p 1, Der f 1 and Blo t 5 were equivalent in atopic and non-atopic dog?s households. Among the allergens studied, Der p 1 was the most commonly found, predominantly in carpets and couches.  aAllergens  aAtopic dermatitis  aDogs  aFur  aMites  aAcaro  aCão  aPelame  aAlergenos  aDermatite atópica  aHouseholds dust  aPoeira1 aFARIAS, M.
