Nachweisrate von antikörpern gegen sieben pathogene in wildschweinen (Sus scrofa) aus baden-württemberg

In November and December 2016, blood samples were collected from 219 hunted wild boars in Baden-Wurttemberg, Germany by puncture of the heart. The serum samples were assigned to six different areas and five weight classes. Samples were examined via serological methods for antibodies directed against classical swine fever virus (CFSV), porcine circovirus type 2 (PCV2), swine influenza virus A (SIV A), porcine reproductive and respiratory syndrome virus (PRRSV), pseudorabies virus (PRV), Salmonella spp. and Brucella spp. (B. suis, B. abortus, B. melitensis). No antibodies were detected against CSFV or PRRSV. For SIV A, PCV2, Salmonella spp. and PRV a detection rate of antibodies of 7.4., 79.7., 16.9 and 2.8% have been revealed, respectively. Brucella spp. specific antibodies were detected in 11.2 % of samples and a significant correlation between counts of Brucella antibody positive animals and area 6 (p<0.001) could be found. Our data confirm that wild boars are carriers of pathogens relevant for humans and domestic pigs and are therefore a potential risk for pathogen introduction into swine herds. Regular studies, preferably using comparable laboratory methods, are needed in order to monitor the regional distribution of diseases within wild boar populations.
