Fig. 3From: Molecular epidemiology analysis of symptomatic and asymptomatic norovirus infections in Chinese infantsSite variability was calculated at nucleotide level using Shannon entropy for norovirus strains isolated from our study. Diversity nucleotide plots, were shown the difference site of the ORF2 (A) and RdRp (B) sequence. Sequence locus information is referenced to GII.4 Sydney 2012 genome (JX459908)Back to article page
