Maximum likelihood phylogenetic tree of the LMP1 gene from the Brazilian samples in this work (n = 82, red circles) and those available in the GenBank database (n = 472, gray circles). Six main clades were observed, marked by different shadings, according to the legend at center (Mediterranean—grouping the references Med+, Med− Daudi, and Mutu; Asian II—grouping the references HKNPC1, M81, Cao, Akata, NPC, and China1; Asian II—grouping the NC, Alaskan, and China2 references; America/Europa—grouping sequences from different countries without a reference strain. The aLRT branch support values are displayed in key branches. Branch lengths are scaled with the bar indicating nucleotide substitutions per site.
