A phylogenetic tree based on amino acid sequences between the detected CDV and reference strains. Bootstrap values (> 50%) are shown at each node of the tree using 10,000 replicates. The scale bar below the tree represents a genetic distance of 0.04 amino acid substitutions per site. The CDV isolate identified in this study is indicated in red and with an asterisk. Sequences are labelled using GenBank accession numbers. SA1/EU: South America 1/Europe; AM1: America 1; AM2: America 2; AS1: Asia 1; AS2: Asia 2; PDV: Phocid distemper virus (was included as an outer group).
