Abstract

Three agar immunoprecipitin techniques (double immunodiffusion, immunoelectrophoresis and immunoelectroosmophoresis-immunodiffusion) made with paracoccidioidin and serum of a paracoccidioidomycosis patient's wife, permitted us to observe a specific band in 6 successive samples of blood taken from the wife over a period of 21 months. The case represents an example of a subclinical paracoccidioidomycosis infection that is usually diagnosed in its disseminated, progressive form. Three possible sources of infection are discussed. But an interhuman contagion appears to be the most feasible.

Resúmen

Tres técnicas de immunoprecipitación en agar (doble difusión, inmunoelectroforesis e inmunoelectroosmoforesis-inmunodifusión) realizadas con paracoccidioidina y suero de la esposa de un paciente con paracoccidioidomicosis, permitieron observar una banda especifica en 6 muestras de sangre, obtenidas en un periodo de 21 meses.

El caso representa un ejemplo de infección paracoccidióidica subclinica, enfermedad que es usualmente diagnosticada en sus formas diseminadas progresivas.

Discutimos tres posibles fuentes de infección, pero consideramos como más probable el contagio interhumano.
