Atopy to dander from domestic animals.
Atopy to dander from domestic animals occurs rather frequently in atopic patients, especially danders from the cat, guinea-pig, horse, rabbit, and golden hamster. There is no clear sex difference. The age group in which the phenomenon is found most frequently is from 21 to 30 years. As in hay-fever patients during the season, we found a double-peaked frequency curve for the blood eosinophilia. Animal-dander atopy was diagnosed particularly in patients with asthma and/or with atopic eczema. The strength of skin reactions to a series of three tenfold dilutions of standardized test extracts appears to be a good index for the origin of clinical symptoms after contact with the relevant animals.
