CPV recombination network.
<p>The phylogenetic network was generated from alignment of 42 complete CPV genome sequences. There are two main clades encompassing CPV-2c and CPV-2a strains (circles), and an edge (split) that reveals a possible recombination event involving strain 364-rec (KM457139). The Phi test for recombination was significant at p = 0.003.</p

Phylogenetic incongruence analysis.
<p>Phylogenetic reconstructions were performed with non-recombinant fragments of the 4269-bp CPV coding region containing nt 1–2500 (A), and nt 2501–4269 (B). The 364-rec strain (arrowhead) associates with both the CPV-2c (A) and CPV-2a (B) clades. 2a-UY: Uruguayan CPV-2a clade; 2c-UY: Uruguayan CPV-2c clade; FPV-US.06: feline panleukopenia virus (EU659115); MEV-CH.09: mink enteritis virus (FJ592174); CPV2-US.79: Canine parvovirus type 2 (M38245); CPV2a-15 United States 2a isolate (M24003); CPV2a-s5/2010 Chinese 2a isolate (KF638400.1). CPV2c-56/00 Italian 2c isolate. CH: China; US: United States; UY: Uruguay.</p
