| Abstract: | Two porcine circovirus type 2(PCV-2),strains DY01 and HN01 were isolated from highly pathogenic porcine reproductive and respiratory syndrome virus-infected samples.The PCV-2 isolates were identified by PCR method.The complete genomes of these PCV-2 isolates were sequenced and their molecular variations analyzed using DNAStar software.Comparison analysis of the complete genomic sequences of two PCV-2 isolates indicated that they were closely related to each other(95.9%)and to other PCV-2 strains in GenBank(93.5%-99.6%).There was 68.9% to 69.3% sequence identity among PCV-2 and PCV-1 isolate genes.Phylogenetic analysis revealed that the two isolates belonged to genotype PCV-2b.This two PCV-2 strains isolated from Henan and Shandong provinces were both belong to PCV-2b type,and this two PCV-2 strains have area lvariation on gene evolution. |
