The ecology of Paracoccidioides brasiliensis: a puzzle still unsolved.


Some aspects pertaining to the ecology of the dimorphic fungus, Paracoccidioides brasiliensis, are reviewed. The available facts concerning the interactions among the only known host (man), the environment (limited to certain Latin-American countries) and the parasite (with an unknown habitat), are analysed. Efforts are made to detect clue circumstances which may lead to discovery of the fungus micro-niche. An analysis of P. brasiliensis mycelial form reveals that such a form has the required capabilities to be the natural infectious form. Its requirements for a moist environment in vitro as well as the high relative humidity predominating in the heart of the endemic areas point towards the possibility of an aquatic--or at least, an extremely humid--habitat for P. brasiliensis.
