LTR phylogenetic tree constructed by the neighbor-joining method with 47 HTLV-1 strains, including 6 new strains from Guyana (with the prefix Gya, in bold), 4 new strains from Suriname (with the prefix Sur, in bold), and 3 previously published strains from French Guiana (CAM, NAR, and NM1626, in bold) for a portion of 480 bp from the LTR. Strain PTM3 (STLV-I strain) was used to root the tree. The numbers along the ancestral segments indicate the robustness of each node, as estimated from 1,000 bootstrap samplings of the data. The geographical origins of the strains other than those from Guyana, Suriname, and French Guiana reported in the cosmopolitan HTLV-1 subtype A are as follows, from top to bottom: BOI, French Caribbean; TSP1, Japan; Cr1, Caribbean; AFS911, South Africa; FCR, MASU, MAQS, AMA, and JCP, Brazil; CMC, Taiwan; CH, Caribbean; MT2-LB, Japan; P73RM, United States; YS, MT4-LB, HKN, H5, HCT, ATK, and ATM, Japanese group; and HS35, Caribbean. The sequences in the LTR phylogenetic tree are reported elsewhere (12, 13, 23, 24, 46, 49, 50).
