The molecular genetic evolution tree of CIAV strains based on the whole genome nucleotide sequence. Sequences from the present study are named as CIAV-Dog and CIAV-Mouse which are shown with a “black triangle.” GenBank sequences were given the strains name followed by country name and time. The three major groups were identified as Group I, Group II, and Group III. The whole sequences were analyzed by using MEGA5.1 software with neighbor-joining (NJ) phylogenetic tree methods together with the novel sequence. Each tree was produced using a consensus of 1000 bootstrap replicates.
