GARCIA, Nilma Maciel et al. Paracoccidioides brasiliensis, a new strain isolated from a fecal matter of a penguin (Pygoscelis adeliae). Rev. Inst. Med. trop. S. Paulo [online]. 1993, vol.35, n.3, pp.227-235. ISSN 1678-9946.

The Authors show lhe results obtained through the study of a Paracoccidioides strain isolated from a penguin in the Uruguaian An-lartide by GEZUELE et al. (1989). From the fecal matter 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 Lhe 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.

Keywords : Paracoccidioides antarcticus; Paracoccidioides brasiliensis; Pinguim.
