Normalized Sarcocystis spp. prevalence in hunting dogs from the wolf area (dark grey, n = 49) and control area without wolves (light grey, n = 29). Hunting dogs were infected with 11 distinct Sarcocystis species, of which two species only occurred in wolf inhabited areas. They were significantly more likely to be infected with the ‘wolf–specialized’ parasite S. grueneri when sharing their habitat with wolves (p = 0.035). It was not possible to determine a correlation for an infection with the other ‘wolf specialist’ S. taeniata and wolf presence (n.s. = not significant, p = 0.476). P values were extracted from GLMs.
