Genome maps of four PCV2 recombinant strains. HN0907 was an intra-genotypic recombinant between PCV2b strains, nucleotides (Position 51 to 413) were from ZhuJi2003 (AY579893, PCV2b) and nucleotides (Position 414 to 995) were from 09CQ (HQ395024, PCV2b). 09HaiN-1 was an inter-genotypic recombinant between PCV2a and PCV2b strains, it exhibited greater similarity to 336 (AY256459, PCV2a) before the breakpoint 309 of ORF2, and shared higher sequence similarity with GSLN-PCV2 (FJ948168, PCV2b) after the breakpoint 309 of ORF2. SXXYA-01 was an inter-genotypic recombinant between PCV2a and PCV2b strains, nucleotides (Position 1034 to 1391) were most from ZhuJi2003 (AY579893) and the remaining sequences were most from DTC (DQ104423). SXXYB-01 was an inter-genotypic recombinant between PCV2a and PCV2b strains, its sequence exhibited higher similarity to DTC (DQ104423, PCV2a) before the breakpoint 1034Â nt and higher similarity to ZhuJi2003 (AY579893, PCV2b) after the breakpoint 1034Â nt. Note: The recombinant regions were presented using red squares and blue squares.
