Phylogenetic tree of amino acid sequences of human and animal smacoviruses (A and B) and pecovirus (C and D) of the replicase and capsid genes, respectively. The trees were constructed using the LG+G+I substitution model using RAxML, with the autoMRE flag, which enables a posteriori bootstrapping analysis. Only bootstrap values greater than 70% are shown. Bars indicate amino acid substitutions per site. Red, Cameroonian human strains; blue, previously known human smacoviruses or pecovirus.
