Summary

Streptomyces olivaceus was isolated from the roof-thatch of New Guinea huts, and a soluble extract was prepared from it. Using sera from New Guinea natives as a source of precipitating antibody, the S. olivaceus antigen showed a reaction of partial identity with antigens in crude roof-thatch extracts.

The inhalation of aerosols of S. olivaceus antigen by guinea-pigs, previously given parenteral doses of the same antigenic solution, induced extrinsic allergic alveolitis.
