Tracing the Origin and Northward Dissemination Dynamics of HIV-1 Subtype C in Brazil
Figure 5
Time-scaled Bayesian MCC tree of the HIV-1 CBR-I lineage.
Branches are colored according to the most probable location state of their descendent nodes as indicated in the legend and map shown on the left. The dotted boxes highlight the position of the Brazilian sub-clade characteristic of Rio Grande do Sul (CBR-RS). The median age (with 95% HPD interval in parentheses) and the PSP values of some key nodes are shown. Key nodes with a high (> 0.85) PP support are marked with an asterisk. Horizontal branch lengths are drawn to scale with the bar at the bottom indicating years. The tree was automatically rooted under the assumption of a relaxed molecular clock.
