Figure 2. Bayesian coalescent analysis of sequence differences of Kyasanur Forest disease virus isolates from India (1957–2006), People’s Republic of China (1989), and Saudi Arabia (1995–2004). Analysis was conducted by using the general time reversible model incorporating invariant sites, a relaxed molecular clock, constant population size, and the BEAST, BEAUTi, and Tracer analysis software (26). The maximum clade credibility tree is depicted. Posterior probability values are indicated for clades of interest with the time to most recent common ancestor shown below. Scale bar indicates nucleotide substitutions per site.
