Figure. Phylogenetic tree of 10 bovine ICV isolates compared with 1 porcine and 195 human ICV isolates (not labeled), United States. Some subtrees containing only human isolates were collapsed to decrease the size of the image. A representative taxon identification number for each collapsed subtree is shown with the number of taxa in the subtree in parentheses. The percentage of trees in which the associated taxa clustered together is shown above the branches. The tree with the highest log likelihood is shown. The tree is drawn to scale, with branch lengths in the same units as those of the evolutionary distances used to infer the phylogenetic tree. Scale bar indicates the relative distance of 0.005, which indicates a 0.5% sequence difference. ICV, influenza C virus.
