Phylogenetic analysis of CCoV strains on the basis of partial S gene sequences.

<p>(A) Phylogenetic tree generated using the nucleotide sequences of the partial S gene of CCoV-IIa. (B) Phylogenetic tree generated using the nucleotide sequences of the partial S gene of CCoV-I. (C) Phylogenetic tree generated using the nucleotide sequences of the partial S gene of CCoV-IIb. Red circles represent the CCoV strains identified in our study.
