Background:Porcine reproductive and respiratory syndrome virus (PRRSV) is the causative agent of porcine reproductive and respiratory syndrome (PRRS) and porcine circovirus type 2 (PCV2) is associated with post-weaning multisystemic wasting syndrome (PMWS) in piglets.Recently,coinfection with highly pathogenic PRRSV (HP-PRRSV) and PCV2 in the field has become global.As previously reported,there is a synergistic pathogenicity in PRRSV and PCV2 coinfection;however,the consequences of sequential infection of pigs with these two viruses have remained unknown.
