Bayesian maximum clade credibility (MCC) tree representing the time-scale phylogeny of CCHFV, as obtained by analysis of 293 long genomic fragments of the nucleoprotein (S segment) coding sequences.

<p>The branches are colored on the basis of the most probable location state of the descendent nodes (see color codes). Numbers at the nodes indicate posterior probability values (clade credibilities ≥90%) and parallel maximum likelihood bootstrap replicates (≥70%). The scale at the bottom of the tree represents the years before the last sampling time (2012). The main clades (genotypes), subclades and Kosovar lineages (dotted squares) are indicated to the right of the tree. The human and tick-derived CCFHV strains are also indicated. Tick-derived sequences derived from this study are designated with “Kosovo I” and “Kosovo IIb”. All remaining sequences were extracted from public databases.
