Genome organization of the Kresse strain of porcine parvovirus: identification of the allotropic determinant and comparison with those of NADL-2 and field isolates

Abstract excerpt

The Kresse strain of porcine parvovirus (PPV) was cloned into pUC19, and independent infectious clones were sequenced. The PPV Kresse and NADL-2 strains, which have different pathogenicities, shared an identical genomic organization and a high degree of sequence identity. Partial genomes (1.5 or 1.6 kb) of 15 field isolates were also amplified by PCR in regions with significant sequence differences between the...
