The aim of this study is to investigate the genetic aspects of PCV2 and to enhance our understanding of the virus's molecular epidemiology and evolution in swine. We collected all available PCV2 ORF2 sequences from the literature, considering the country of collection, date, and host, to analyze the viral population dynamics, spread, and evolutionary patterns. Specifically, we compared the selective pressures acting on strains circulating in domestic pigs and wild boars. The results provide insights into viral dispersal patterns and how different hosts, due to their biological characteristics and immunity (largely influenced by vaccination), may contribute to viral evolution.
L’obiettivo di questo studio è indagare gli aspetti genetici del PCV2 e migliorare la nostra comprensione dell’epidemiologia molecolare e dell’evoluzione del virus nei suini. Abbiamo raccolto tutte le sequenze disponibili dell’ORF2 del PCV2 dalla letteratura, considerando il paese di raccolta, la data e l’ospite, per analizzare le dinamiche della popolazione virale, la diffusione e i modelli evolutivi. In particolare, abbiamo confrontato le pressioni selettive che agiscono sui ceppi che circolano nei maiali domestici e nei cinghiali. I risultati forniscono approfondimenti sui modelli di dispersione virale e su come diversi ospiti, a causa delle loro caratteristiche biologiche e dell’immunità (largamente influenzata dalla vaccinazione), possano contribuire all’evoluzione del virus.

Abstract
The aim of this study is to investigate the genetic aspects of PCV2 and to enhance our understanding of the virus's molecular epidemiology and evolution in swine. We collected all available PCV2 ORF2 sequences from the literature, considering the country of collection, date, and host, to analyze the viral population dynamics, spread, and evolutionary patterns. Specifically, we compared the selective pressures acting on strains circulating in domestic pigs and wild boars. The results provide insights into viral dispersal patterns and how different hosts, due to their biological characteristics and immunity (largely influenced by vaccination), may contribute to viral evolution.File | Dimensione | Formato | |
