Characterisation of pseudorabies virus in domestic pigs and wild boars in Croatia

Serological data implies that pseudorabies is present in domestic pigs and wild boars in Croatia. Therefore, this study included testing of brain tissue samples collected from 200 domestic pigs and 105 wild boars originating from seventeen districts in Croatia. The presence of PrV DNA was confirmed in samples originating from six domestic pigs (3%) and one wild boar (0.95%). Positive samples were sequenced and analysed on the basis of a gC genome fragment. PrV strains have shown to be genetically identical and they are strongly related to some representative strains in relatively heterogeneous Clade A. The results clearly show that PrV is still circulating among domestic pig population in Croatia. Furthermore, the presence of pseudorabies virus in wild boars underlines the importance of this species as PrV reservoirs. The continued surveillance is necessary to track the viral spread which may lead to final eradication of the disease.
