Phylogenetic tree of C region.

<p>Phylogenetic tree constructed by the Neighbor-joining method based on the partial nucleotide sequence of the norovirus VP1 capsid protein gene C region. Highlighted strains identified by “Sapê”, originated in fecal samples from “Quilombola” children and were analyzed along with the prototype norovirus genotypes of GI, GII and GIV taken from the “GenBank.” All strains were identified by genotype/accession number/year/origin. Sapovirus/AB630067.2/2008/JP was added as a reference group. Values of “Bootstrap (2,000 replicates) are shown at the junction of the branches. • Samples Q51, Q151 and Q220 belong to another study site near the Quilombola communities. ♦ Samples of this study.
