We used PCR to detect Toxoplasma gondii in the principal game species in southwestern Spain. We detected T. gondii in 32.2% of animals tested. Prevalences varied from 14.7% in wild boar (Sus scrofa) to 51.2% in red fox (Vulpes vulpes). The most prevalent genotype was type II (50.0%), followed by type III (20.6%) and type I (5.9%). Mixed infections (11.8%) were detected in wild boar (types I III) and red fox (types II III). Polymorphic strains (11.8%) were detected in several species. The high prevalence and the genetic variability shown could have implications for infection of farm animals and humans.
