Partial Analysis of the Capsid Protein (VP1) of Human Sapovirus Isolated from Children with Diarrhoea in Rural Communities of South Africa

Figure 2

Phylogenetic analysis of the partial polyprotein of human SV-GI detected in Vhembe district (South Africa) and reference strains selected from the GenBank database. The percentage of replicate trees in which the associated taxa clustered together in the bootstrap test (1000 replicates) are shown next to the branches. A bar scale representing a genetic distance scale. The phylogenetic tree was deduced by the maximum likelihood method and the Kimura 2-parameter model using MEGA 11 [20, 21], based on a 709-nucleotide sequence fragment of the polyprotein (a VP1 segment) showing relationships of SV strains. The porcine SV (MF766258) was selected as an outgroup strain.
