Figure 6. Phylogenetic analysis of the norovirus sequences from FPV-cases and healthy controls using the capsid protein amino acid alignment and the LG+F+R3 amino acid substitution model. The norovirus sequence from the FPV-case cat #202 is coloured in blue and from the healthy control cat #CPS73 in red. The scale bar represents the number of amino acid substitutions per site. The tree was midpoint rooted for clarity only.
