RESUMO

By using PEG (polyethylen glycol 6000) in the gel immunodiffusion tests (ID), the precipitin lines were increased in 25.5% of the 192 sera reactions and the titers were increased from one to four serial dilutions in 44.6% of the 139 serum samples. Owing to its sensitivity, easy interpretation of the results and low cost, the use of 2% PEG incorporated into the gel in ID tests is recommended for the diagnosis and serological follow-up of paracoccidioidomycosis infections.
