To the Editor: We thank Liccardi et al for raising an interesting topic for discussion-the issue of passive transport of allergens. The topic was raised because of some findings described in our study on Can f 1 levels in so-called hypoallergenic dog breeds. Passive transport and transfer of allergens from one to another environmental compartment is indeed an underestimated source of allergen exposure that can trigger allergic symptoms, even in environments in which the primary source of the allergen is absent.However, we believe that passive transfer did not dramatically influence the results of our study.
