Porcine circovirus genotype 2a (PCV2a) and genotype 2b (PCV2b) recombinant mutants showed significantly enhanced viral replication and altered antigenicity in vitro.

Abstract excerpt

Two recombinant mutants of porcine circovirus type 2 (PCV2), which resulted from replacement of a genomic fragment containing the open reading frame 2 (ORF2) of genotype PCV2b with that of genotype PCV2a, were obtained initially from co-infection with PCV2a and 2b genotype viruses in vitro. The two mutant viruses contained the ORF1 sequence from genotype PCV2b and the ORF2 sequence from genotype PCV2a. They were...
