Helminths of wild boar in Spain

Forty-seven wild boars (Sus scrofa) collected from two areas in the province of Valencia (eastern Spain) were examined for digestive and respiratory helminth parasites. Helminth species and their prevalence were Taenia hydatigena cysticercus (19%), Ascarops strongylina (87%), Physocephalus sexalatus (6%), Ascaris suum (2%), Metastrongylus spp. (85%), Capillaria sp. (2%) and Macracanthorhynchus hirudinaceus (21%). Trichinella spp. were not found. Physocephalus sexalatus, A. suum, Capillaria sp. and M. hirudinaceus were found only in wild boars collected from one area (National Hunting Reserve of Cortes de Pallás). Macracanthorhynchus hirudinaceus did not occur in hogs < 1-yr-old, whereas the intensity of Metastrongylus spp. infection was the greatest in this age group.
