"Hypersensitivity pneumonitis" is a term defining a category of diseases caused by the inhalation of organic dusts. Many individuals are exposed to such organic dusts, and this hypersensitivity reaction has been reported in farmers , mushroom pickers, maple-bark strippers , malt workers, and bird fanciers. It is therefore of value to identify the etiologic agents of such hypersensitivity reactions and to study the pathogenesis of the disease in order to achieve a better treatment for victims of these diseases and perhaps a means of prophylaxis for those exposed to such occupational hazards can be developed. The study of these reactions could also lead to a better understanding of the genesis of many hypersensitivity reactions in humans.
