Genetic Diversity of Porcine Circovirus Types 2 and 3 in Wild Boar in Italy.

Five PCV2 strains identified in this study showed the highest nt identities (99.2-100%) to PCV2 strains retrieved from the GenBank database whilst strain ITA/2021/434 was more distantly related (88.8% nt identity) to strain 71b Vicenza 36 (GenBank accession nr KP231135) identified from a domestic pig in Italy in 2008. The complete PCV genome sequence was obtained only from 11 (5 PCV2 and 6 PCV3) Italian wild boar (Table S4). The prevalence of PCV3 in wild boar in our survey was nearly as high (71%) as in Sardinia Island (77.39% in free ranging pigs and 61.54% in wild boar) [[17]], but higher than the prevalence of PCV3 detected in the Campania region (49.32%) [[15]] and in other Mediterranean countries (e.g., 42.66% in Spain) [[11]].
