Nasal Eosinophilia in So‐called Bacterial Hypersensitivity in Asthmatic Children Preliminary Report

Summary A preliminary report is given of some studies concerning bacterial vaccines in asthmatic children. A method is introduced in which nasal eosinophilia is studied in connection with local applications of bacterial vaccines and controls. A repro‐ducable positive response is found in three patients of a selected group suffering from presumed “bacterial allergy”. In two of these patients focal asthmatic reactions are observed following the injection of minute doses of the vaccine in question. The method is briefly discussed.
