2001

Seven PPV isolates from different natural hosts were compared on the base of amino acid sequences of their coat protein genes.The results obtained allowed the division of that isolates into two subgroups - A and B.Two of the isolates, PPV-C and PPV-NL showed high level of identity with D and AT isolates and were placed into subgroup A. PPV-P48, PPV-P45 and PPV-II/7 shared significant sequence homology also with D and AT strains, but they all had deletions in their coat proteins and formed a detached subcloster into subgroup A. PPV-A and PPV-P isolates were placed into subgroup B, on the base of high level of identities with the Hungarium isolate SK-68.
