Intrahost Diversity of Feline Coronavirus: A Consensus between the Circulating Virulent/Avirulent Strains and the Internal Mutation Hypotheses?
Neighbour-joining MCL phylogenetic tree of the M gene partial sequences of FCoV (positions from 26293 to 26907 regarding strain FCoV UU47). The tree was constructed using a canine coronavirus sequence as an outgroup (GQ477367). Numbers on the nodes indicate the bootstrap support from 1,000 replications. Only bootstrap values >50 are shown. The scale bar represents the number of substitutions per nucleotide. The numbers from 1 to 15 identify each cat.
