Tanglegram of phylogenies of GBV-A virus (right) with the New World monkeys species from which they were isolated (left). Monkey species: SM, Saguinus mystax; SL, Saguinus labiatus; SO, Saguinus oedipus; SN, Saguinus nigricollis; CJ, Callithrix jacchus; AT, Aotus trivirgatus. In the case of SL and SN two phylogenetically distinct lineages were observed in each species data set, denoted ‘a’ and ‘b,’ respectively
