The contribution of integrated and non-integrated pig farms to epidemiological dynamics of porcine reproductive and respiratory syndrome virus in Italy.

ABSTRACT: Porcine reproductive and respiratory syndrome (PRRS) is a global challenge for swine production. Due to its high variability and limited cross-protection, immune-based control measures are only partially effective, emphasizing the critical role of biosecurity. A prior study on Italy's largest integrated pig production company demonstrated the effectiveness of hierarchical organization in separating pig flows but, through biostatistical estimations, highlighted vulnerabilities, particularly the role of non-integrated farms in introducing new variants into the integrated system. Over 500 PRRSV sequences from integrated and non-integrated farms in central-northern Italy were analysed in the present study using phylogenetic, phylodynamic, and phylogeographic approaches. Two main PRRSV clades w
