Comparison between magnetic enzyme-linked immunosorbent assay (MELISA) and complement fixation test (CF) in the diagnosis of paracoccidioidomycosis.

MELISA and CF were compared using sera from paracoccidioidomycosis patients before treatment and patients undergoing antimycotic treatment. With MELISA it was possible to distinguish different antibody levels in both groups of patients whereas such distinction was not observed by using CF tests. MELISA is thus an advantageous alternative to CF in the diagnosis of paracoccidioidomycosis, including the possibility of testing sera with anticomplementary activity.
