Fig. 2From: Clinical and molecular analyses of norovirus-associated sporadic acute gastroenteritis: the emergence of GII.17 over GII.4, Huzhou, China, 2015Phylogenetic analysis based on RdRp (RNA-dependent RNA polymerase) genes a and partial capsid protein (VP1) genes a of genogroup I noroviruses. Phylogenetic analysis based on RdRp genes a and partial VP1 genes b of GI NoVs. The trees were constructed by the neighbor-joining method with by the neighbor-joining method with the Maximum Composite Likelihood model in MEGA (version 6.0), validated by 1000 bootstrap replicates. Bootstrap values more than 70% was shown on the branches. NoV strains identified in Huzhou are designated by location, year and sample number (indicated by black triangles). Reference sequences are indicated by their genotypes and accession numbers. The GIII.2 strain (AY126474) was used as outgroupBack to article page
