Serotype G12 Rotaviruses, Lilongwe, Malawi
Figure 2. Phylogenetic tree based on VP7 nucleotide sequences from representative Malawi G12 strains and G12 strains deposited in DNA databases. Strain designations are followed by country of origin. Malawi strain KCH1051 is genotype G12P and has an indeterminate RNA profile. Horizontal lengths are proportional to the genetic distance calculated with the Kimura 2-parameter method. Number adjacent to the node represents the bootstrap value of 1,000 replicates and values <80% are not indicated. Scale bar shows genetic distance expressed as nucleotide substitutions per site.
