Rapid diagnosis of pulmonary mycosis by counterelectrophoresis

Detection of precipitins in sera from pulmonary mycoses by the counterimmunoelectrophoresis technic is reported. This method is based on the application of a constant current of high potency on the Outcherlony technic with the result of a greater concentration of the reagents in the precipitation area and a greater speed of the reaction which can be read after one hour. We have registered positive results in all of 73 sera from patients mycologically proved of S. A. blastomycosis, coccidioidomycoses, histoplasmosis and aspergillosis. No cross reactions have been observed.
