In vitro demonstration of specific immunological hypersensitivity to scabies mite.

摘要: SUMMARY An extract prepared from 200 adult female scabies mites was used for prick and intracutaneous testing in twelve patients with previous infestation, as well six healthy controls three persons skin sensitivity to Dermatophagoides pteronyssinus who had never before. Seven individuals less than a year prior the positive (immediate type) reactions, whereas all five more before negative reactions. The tests were cases. No reactions could be evoked controls. passive transfer, or Prausnitz-Kustner, test mite serum of tested on one individual, both two sera second individual. These findings indicate that immediate type hypersensitivity may occur infection.
