Fig. 3From: Continuous detection and genetic diversity of human rotavirus A in sewage in eastern China, 2013–2014Phylogenetic relationship of G9 sequences (a), G2, G4, G6 and G8 sequences (b). The phylogenetic trees were constructed based on 884-nt RVA VP7 sequence according to nt position 49–932 of strain Human-tc/USA/Wa/1974 segment 9 (JX406755). ● and ▲ indicate sequences from sewage sample and reference strains from China, respectivelyBack to article page
