Figure 2. Phylogenetic analyses of sequences of Shandong rubella viruses based on the WHO standard sequence window.

Figure 2

(a) Phylogenetic analysis of sequences of 24 representative rubella viruses from 2000–2009 compared with the WHO reference sequences. Numbers in parentheses are numbers of identical sequences found in the same outbreak. Shandong rubella viruses are indicated by a solid circle. (b) Phylogenetic analysis of representative Shandong rubella virus strains of genotype 1E compared with rubella viruses from the other provinces of China. Seventy-seven genotype 1E rubella virus strains from other provinces isolated during 2001–2009 were obtained from Genbank. Shandong rubella viruses are indicated by red solid circles, the genotype 1E rubella virus strains from other countries are indicated by blue solid triangle. The Chinese vaccine strain BRD II with a green solid square was used as an out-group.
