[Paracoccidioides brasiliensis, a new sample isolated from feces of a penguin (Pygoscelis adeliae)]

The Authors show the results obtained through the study of a Paracoccidioides strain isolated from a penguin in the Uruguaian Antartide by GEZUELE et al. (1989). From the fecal mater it was isolated a fungus which was recently considered as a new species of the genus Paracoccidioides--P. antarcticus. However, the mycological and immunochemical studies including the demonstration of the 43 kDa glycoprotein by immunodiffusion test, SDS-PAGE and immunoelectrophoresis disclosed that such strain is similar to P. brasiliensis. Other studies, based on molecular taxonomy, including karyotyping, are the only tools to confirm the possibility of such strain to be a variant of P. brasiliensis. The Authors report the epidemiological significance of that finding and suggest a review in the knowledge of the ecological "niche" of P. brasiliensis.
