Phylogenetic analysis of STLV-3 pX -LTR sequences. Inference of PTLV-3 phylogeny using 900-bp tax-pX-LTR sequences. Reference sequences used were as follow: STLV-3 (Cto604_AF391797, Cto-NG409_AY222339, Ppa-F3_AF517775, TGE-2117_AY217650, Pha969_Y07616, Lal01CM2090_AM712666, Lal01CM3086_AM712667, Lal01CM4009_AM712672, Lal01CM2008_AM712673, Cag01CM4031_AM712670, Cag01CM2279_AM712669, Cmo8699AB_EU231644, Cni7867AB_EU152281, Cni3034_FJ957877, Cni3038_FJ957878), HTLV-3 (Pyl 43_DQ462191, Loback 18_EU649782, 2026ND_DQ093792, Cam2013_GQ463602). Numbers correspond to internal branch support derived from 1000 bootstrap replications (only values ≥ 80% are shown and represented by an asterisk except for the non-significant bootstrap percentage (59.6%) for the putative new STLV-3 subtype CtoOMGAB57). Scale bar represents the number of nucleotide substitution per site. Groves’ primate taxonomy nomenclature is used [40]. Non-human primates are coded using the first letter of the genus followed by the first two letters of the species name: Cto = Cercocebus torquatus, Cag = Cercocebus agilis, Lal = Lophocebus albigena, Cni = Cercopithecus. Nictitans, Ppa = Papio hamadryas papio, Tge = Therppithecus gelada, Pha = Papio hamadryas. Sequences in bold text and in grey rectangles are from the current study.
