Molecular Diversity of Sapovirus Infection in Outpatients Living in Nanjing, China (2011–2013)

Figure 1

Phylogenetic analysis of the partial N terminal capsid gene (358 bp to 364 bp) of SaV strains identified in outpatients in Nanjing, China, between April 2011 and October 2013. The tree was constructed on the basis of the Kimura 2-parameter and neighbor-joining methods with MEGA5 software (http://www.megasoftware.net/) as described in Methods. The analysis involved 60 nucleotide sequences, 14 strains found in Nanjing presented as the year of detection and strain number, and 46 additional worldwide sequences presented with the NCBI accession number and details. GI, GII, GVI, and GV were genogroups, and GI.1, GI.2, GI.3, GI.4, and GI.5 were genotypes.
