Farmer's lung serologies. An early manifestation of acute histoplasmosis.
Three cases of acute histoplasmosis demonstrated, in addition to the usual serologic findings, strongly positive precipitins against farmer's lung antigens. Twelve additional serums from patients with acute histoplasmosis were subsequently studied. Forty percent of these patients demonstrated positive precipitins against organic dust antigens.
