| Summary: | In 1989, CONTI DÍAZ & RILLA published a hypothesis concerning the as yet unknown ecological niche of Paracoccidioides brasiliensis. The hypothesis proposed a highly efficient paracoccidioidal ecological strategy based on an important natural reservoir of the parasite, probably in heterothermic animals from fresh water environments. Further, the hypothesis proposed, a transient and variable residence in the soil with a wide aleuriospore dispersion throughout the environment together with an elevated capability of infecting humans, and domestic and wild animals. This paper analyzes scientific publications from the IX International Meeting on Paracoccidioidomycosis held in Águas de Lindoia, São Paulo, Brazil from 2-5 October 2005, providing a comparative study among this articles and with other recently published papers and the hypothesis' postulates. Since various findings and observations appear to agree with the postulates, the pursuit of novel, specific research projects in the supposed reservoirs is recommended partially or fully to confirm the hypothesis using classical laboratorial methods and modern molecular biology techniques. En 1989 CONTI DÍAZ & RILLA publicaron una hipótesis sobre el aún hoy desconocido nicho ecológico de Paracoccidioides brasiliensis proponiendo esencialmente en ella la existencia de una estrategia ecológica altamente eficiente del agente. al estrategia estaría basada en una importante reserva del parásito en animales heterotérmicos de fuentes naturales de agua dulce, una estadía sólo transitoria y de variable duración en el suelo, con una amplia dispersión de aleuriosporos en el ambiente exterior con capacidad de infectar al hombre y a los animales. El presente trabajo analiza comunicaciones científicas del último Encuentro Internacional sobre Paracoccidioidomicosis celebrado en Aguas de Lindoia, San Pablo, Brasil, entre el 2 y 5 de octubre del 2005, comparando diferentes conceptos y resultados allí emitidos como también de otros trabajos al respecto, con los postulados de la ... |
