Type 1 wild-vaccine recombinant polioviruses were isolated from poliomyelitis patients in China from 1991 to 1993. We compared the sequences of 34 recombinant isolates over the 1,353-nucleotide (nt) g
The analyses were done with the SRD06 substitution model and a relaxed molecular clock model implementing either an uncorrelated exponential (UCED) or an uncorrelated lognormal (UCLN) distribution of
tMRCA estimations for NS5B data sets. Results correspond to Bayesian Skyline Plots run under the GTR+Γ+I model of nucleotide substitution using a relaxed clock model (uncorrelated lognormal) and setti
