From 2004 to 2007, blood samples from 273 healthy wild boars (Sus scrofa), culled during the hunting season, were obtained in three areas of Catalonia (NE Spain): Pyrenees, Sant Llorenç del Munt i l’Obac Natural Park (SLM), and Ports de Tortosa i Beseit National Hunting Reserve (PTB). We investigated the presence of antibodies against classical swine fever virus (CSFV), African swine fever virus (ASFV), porcine vesicular disease virus (PVDV), porcine respiratory and reproductive syndrome virus (PRRSV), Aujeszky’s disease virus (ADV), porcine influenza A virus (PIV), porcine circovirus type 2 (PCV2), porcine parvovirus (PPV), Mycoplasma hyopneumoniae, Erysipelothrix rhusiopathiae, Salmonella spp., and Toxoplasma gondii. Four wild boars were suspicious for CSFV, but the infection was discarded with a virus neutralization test, and infection with a border disease virus was confirmed. Negative results were obtained against ASFV and PVDV. Antibodies were detected against PRRSV (3%), ADV (0.8%), PIV (6.4%), PCV2 (64.6%), PPV (54.7%), M. hyopneumoniae (26.6%), E. rhusiopathiae (5.3%), Salmonella spp. (11.3%), and T. gondii (43.5%). In SLM, we detected a higher seroprevalence for PIV and M. hyopneumoniae and a lower seroprevalence for E. rhusiopathiae than in the other two areas. In PTB, seroprevalence was higher for PPV, Salmonella spp., and PCV2. Adult wild boar displayed higher seroprevalence for PPV, PIV, and M. hyopneumoniae, whereas presence of antibodies for Salmonella spp. was higher in juveniles compared with adults and piglets.
