Popis: We have isolated 4 naturally-occurring strains of CPV in mainland China and have identified them as CPV-2, 2a, 2b and 2c genotypes according to their VP2 sequences which also revealed substitutions within their right terminal regions. To determine if these substitutions affected the growth characteristics of the 4 strains, we constructed plasmids based on their genomic sequences minus their right terminal sequences, with the latter replaced by a single right terminal region. Analysis of rescued recombinants showed that the substitutions within their natural right termini had no significant effect on their growth characteristics.
