Fig. 4From: Continuous detection and genetic diversity of human rotavirus A in sewage in eastern China, 2013–2014Phylogenetic relationship of P[8] sequences (a), P[4] sequences (b), P[3], P[6] and P[9] sequences (c). The phylogenetic trees were constructed based on 664-nt RVA VP4 sequence according to nt position 142–805 of strain Human-tc/USA/Wa/1974 segment 4 (JX406750). ● and ▲ indicate sequences from sewage sample and reference strains from China, respectivelyBack to article page
