[Immunologic investigations of house-dust and house-dust mites. I. Schultz-Dale test (author's transl)].

With Dermatophagoides pteronyssinus and house-dust sensitized guinea-pigs showed cross-reactions between house-dust, D. pteronyssinus and D. farinae in the Schultz-Dale test. Euroglyphus maynei gave positive reactions only in animals sensitized with D. pteronyssinus. The stored food mites Tyrophagus putrescentiae, Chortoglyphus arcuatus and Glycyphagus destructor and the rearing medium (horse dander/yeast) did not cause any cross-reactions in any test group.
