title: [Value of co-immunoelectrodiffusion on cellulose acetate for the demonstration of remarkable precipitating systems in the diagnosis of farmer's lung].
abstract: Farmer's Lung is an extrinsic allergic alveolitis due to the inhalation of actinomycetes thermophiles. Micropolyspora faeni is the principal allergen implicated in this disease which is very difficult to diagnose. The authors discuss the value of immuno-electro-diffusion on cellulose acetate which is a rapid and sensitive technique for the demonstration of remarkable precipitating systems: polysaccharide and chymotrypsin arcs. This investigation enables subjects who really have the disease to be distinguished from "contact" subjects.
