Six free-ranging European beavers (Castor fiber) from Berlin greater metropolitan area and twelve European wildcats (Felis silvestris silvestris) originating from the German Federal State of Saxony-Anhalt were found dead and their carcasses were submitted for necropsy. Brain and lung samples were analysed for the presence of Toxoplasma gondii DNA. Histo-pathologic analysis of one beaver revealed several cyst-like protozoal structures in parts of the brain. Tissue DNA isolated from all animal samples was analysed by a specific T. gondii-PCR. Two beavers and four wildcats tested T. gondii-positive. DNA of the parasites was further analysed by PCR-RFLP typing using nine markers (nSAG2, SAG3, BTUB, GRA6, c22-8, c29-2, L358, PK1 and Apico). Only T. gondii type II alleles were detected, except for the Apico locus, where type I alleles were observed in two isolates from beavers and in three from wild cats. The results of this study indicate that type II T. gondii (including type II variant strain) is the most common genotype infecting wildcats and beavers from Germany.
