Abstract excerpt

Porcine reproductive and respiratory syndrome virus (PRRSV) remains a major threat to the swine industry globally. In China, the dominance of PRRSV 2 is complicated by the emergence and co-circulation of genetically distinct strains, including a rising number of PRRSV 1 cases. In this study, the concurrent circulation of PRRSV 1 and PRRSV 2 was identified, and two novel strains AHB1 and Chah2022 were isolated...
