Electrophoretic migration of Paracoccidioides brasiliensis specific antigenic fraction.

Using the technique of immunoelectroosmophoresis-immunodiffusion (IEOP-ID), two antigenic fractions of Paracoccidioides brasiliensis one of them species-specific, produced precipitin bands in both the cathodic and anodic zones. Reactions of complete identity among the bands formed in these zones were demonstrated by a modification of the technique, employing additional wells around the central antigen well. Such bands would correspond to a simple diffusion of the corresponding antigenic fractions rather than to active electrophoretic migration.

[Comparative study of immunoelectrophoresis (IEF) and immunoelectroosmophoresis-immunodiffusion (IEOF-ID) used in the diagnosis of paracoccidioidomycosis].

Immunoelectroporesis (IEF) and immunoelectroosmophoresis-immunodiffusion (IEOP-ID) (1) were comparatively used in the diagnosis of 16 patients with mycologically proved paracocidioidomycosis. In IEF, 5 different precipitin arcs were found and identified with arabic numbers. Arc. '1', cathodic, present in all the patients, is assimilated to specific arcs previously described by other authors. In IEOP-ID both 'cathodic' and 'anodic' arcs were observed in all the sera. A high number of precipitin arcs were revealed by IEOP-ID technique in comparison to IEF in every case. This should be due to the presence of cathodic arcs 'I' and '2' of the immunoelectrophoregram at both sides of the IEOP-ID preparate.
