Dioctophymosis is a parasitic disease caused by Dioctophyma renale (Goeze, 1782) with a worldwide occurrence and affects domestic animals as well as wildlife. In March 2010, a ferret adult male, Galictis cuja (Molina, 1782), found dead by trampling in the county of Guaíra, state of Paraná, Brazil, was necropsied in the Veterinary Pathology Laboratory at Campus Palotina, Federal University of Paraná. The animal was in good nutritional condition and moderate autolysis. Three specimens of parasites were found in the abdominal cavity, but the kidneys were preserved. The parasites were fixed in acetic formaldehyde and sent to the Veterinary Laboratory of Parasitology, Campus Palotina, for identification. The parasites were identified as Dioctophyma renale, two females, one a 39cm long and 4mm wide and the other 16cm long and 4mm wide, and a male 16cm long and 3mm wide. This paper reports D. renale parasitism in G. cuja in the western of Paraná state, Brazil.
