Figure 4 . Phylogenetic analysis of the Mamastrovirus2 sequences identified in FPV-cases and healthy controls using
the ORF1b and capsid protein amino acid alignment and LG+R3 and LG+F+R8
amino acid substitution model, respectively. The Mamastrovirus 2sequences from the FPV-case libraries are presented in blue, the
sequences from the healthy control libraries in red and the feline
astrovirus species and Mamastrovirus 2 sequence identified in the
pilot study in green. The scale bar represents the number of amino acid
substitutions per site. The tree was midpoint rooted for clarity only.
