Seroprevalence of antibodies against swine influenza virus in farm swines of different age in Croatia

The results of this study indicate that SIV subtypes H1N1 and H3N2 are circulating in commercial pig herds in the eastern part of Croatia. However, it is evident that the subtype H1N1 is predominant. The obtained results also demonstrated that the occurrence of antibodies depends on the age of animals and show that sows and gilts have higher antibody prevalence against SIV. This might be explained by the fact that sows represent a reservoir for continuous circulation of influenza viruses since most of them have been on the farm longer than the finishing pigs and have more exposure to infection (3). The animals sampled in this study have not been vaccinated against SIV so the seropositive animals may have been exposed to the virus at some point in their life-time from other infected pigs or even humans.
