From: Prevalence of Korean cats with natural feline coronavirus infections
Phylogenetic relationships between partial spike gene sequences of 46 coronaviruses. The samples were comprised of 16 FCoVs from Korea, 23 FCoVs from around the world, five CCoVs, one RDCoV, and one CFBCoV. All sequences except the 16 FCoV sequences derived from the current study (in boldface) were obtained from GenBank. An unrooted phylogenetic tree was constructed from aligned sequences by the neighbor-joining (NJ) method using MEGA 4.0 software. Bootstrap percentages are shown above those branches that are supported in at least 60% of the 1,000 replicates. Scale bar indicates nucleotide substitutions per site.
