From: Isolation and phylogenetic analysis of feline calicivirus strains from various region of China
ORF2 nucleotide sequence-based phylogenetic tree of 26 new isolates and reference strains retrieved from GenBank. Phylogenetic trees were constructed by the neighbor-joining method with 1000 bootstrap replicates using a Kimura 2-parameter model in the MEGA x software package. The 26 new isolates are marked with red triangles (
), and the vaccine strains are marked with black spot (●). The genotype I branch is marked in red, and the genotype II branch is marked in green. Reference strains and GenBank accession numbers are indicated on the branch, and VSD strain names are in red font
