Abstract
Host dust and dust mite are important allergens in canine atopic dermatitis. The purpose of this study was to investigate sensitivity to house dust and dust mite in atopic dogs in Taipei city. One hundred atopic dogs were enrolled according to history, clinical signs ,physical and dermatological exams. Intradermal test with house dust and dust mite were performed and investigated. The diagnosis of atopic dermatitis of each dog was based upon the clinical manifestations compatible to criteria, and results of intradermal skin tests. fifty females and fifty males aged from one to forteen years old with twenrt-three breeds . The mean age of this series was 5.7years. Among these One hundred dogs, eighty six dogs (86%) exhibited positive reactions to either house dust or dust mite, or both. Positive reactions to house dust and dust mite were 15% (15/100) and 3% (3/100) respectively. Positive reaction to both allergens was 68% (68/100). No breed, age predilection found in this series. Sex and body weight were statistical related to positive reaction (either house or dust mite), Analyses between sex, age, body weight and positive reaction to house dust, positive reaction to dust mite, and positive reaction either to house dust or dust mite reveals statistically related between body weight and positive reaction. Percentage of cases exhibited positive reaction to both allergens was significantly higher than that of cases reacted to either allergen alone. This suggested that positive reaction to either allergen would be associated to each other. Further investigation would be needed to clarify the cross-reaction between house dust and dust mites. This study suggests the high positive rate of intradermal tests to house dust and dust mite. House dust and dust mite are common and important allergens in atopic dogs at Taipei area.
