A one-year case study of farmers with storage mite allergy.
Four farmers with a positive bronchial challenge test to either L. destructor or T. putrescentiae had bronchial histamine challenge every second month during a year. In the same year, monthly samples of house dust, grain, straw and hay were analyzed for their content of house dust mites and storage mites. The exposure to house dust mites and storage mites differed between farmers. Significant changes in histamine reactivity were found, but no association with time of year or mite counts was observed.
