Sequence analysis of PCR productsUsing DNAstar software, the sequencing data from eight CPVstrains from Shandong and three MEV strains were aligned andcompared with the sequences of 18 strains from GenBank, includ-ing CPV-N (M19296), CPV-Y1 (D26079), MEV-d (U22190), MEV-e(U22191), and FPV-d (U22189).
