| Assesment of swine influenza occurence in wild boars in Poland, based on serological study |
| Wild boars (Sus scrofa) are widely distributed in many countries in the world. In last years this population is expanding in most of the regions, despite hunting. Wild boars are known reservoirs for a number of infectious diseases that are transmissible to pigs and human. Swine influenza (SI) is viral respiratory diseases of pigs of substantial importance for both, the economy of swine production sector and public health. The aim of the paper is to describe the exposure to SIV of 2801 wild boars hunted in 12 voivodeships of Poland, from 2011 till 2014. It was assessed by HI test. In 2011/2012 the antibodies against H1N1 were evidenced in 6.43% wild boars’ sera. In 3.07% of sera the seroconversion to H3N2 was noted. In 2012/2013 6.23% of sera were examined positive to H1N1, 2.67% of sera were positive to H3N2 and 3.76% of sera had antibodies to A(H1N1)2009pdm-like. In the following hunting season antibodies to H1N1, H3N2 and A(H1N1)2009pdm-like were detected in 7.74%, 2.27% and 1.74% of samples, respectively. In 2011-2014 there were no sera samples positive to H1N2 virus. In total the percent of wild boars with antibodies to SIV range from 0 to 6.25, depending of the subtype. In some animals mixed infections with different subtypes of SIV were evidenced. In general the antibodies titers were low. In summary, we confirm exposure of wild boar’s population to SIV in Poland. Based on the obtained results we suggest that their role in SIV transmission to pig or human is limited. This situation might change therefore further monitoring of wild boar’ health status should be continued. |
