title: Phylogenetic analysis of canine parvovirus CPV-2 strains and its variants isolated in Poland.
abstract: Canine parvovirus disease appeared in the world and in Europe during the second half of the 1970s. Over the course of 40 years the original CPV-2 strains mutated and variants 2a, 2b and 2c appeared. Their appearance is connected with specific amino acid changes, mainly in the capsid protein VP2. Strains isolated by the authors were adapted for in vitro cell culture. Phylogenetic analysis revealed differences between strains isolated in Poland in 1982-1985 and in 1995-2009. Strains from the 1980s were shown to belong to variant CPV-2a (11 strains) and variant 2b (2 strains), while no fundamental differences were found among the genetic profiles of the strains from 1995-2009, which were classified as belonging to variant 2c.
