“…This new lifestyle has increased exposure to allergens, leading to the development of (Thomas 2010). Previous studies performed in various Brazilian cities (Geller 1996, Medeiros et al 2002, Rego et al 2003, Rullo et al 2005 showed that Dermatophagoides pteronyssinus and Blomia tropicalis are important sensitizing agents in human patients with rhinitis and allergic asthma.…”

2 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 0.25µg/g compared to 0.03µg/g in healthy dogs. In households with atopic dogs the highest concentrations of Der p 1 were found in carpets (2.18µg/g), followed by couches (1.53µg/g), beds (1.14µg/g), dogs' bed linen (0.64µg/g) and floors (0.14µg/g). The concentrations of Der p 1 on carpets, couches and beds were significantly higher than in atopic dogs' fur (p<0.05). There was no statistical difference when comparing the concentrations of Der f 1 and Blo t 5 in different environments of atopic dogs (p>0.05). 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.
