Abstract

Over the past few decades, a large number of studies have identified herpesvirus sequences from many mammalian species around the world. Among the different nonhuman primate species tested so far for cytomegaloviruses (CMVs), only a few were from the New World. Seeking to identify CMV homologues in New World monkeys (NWMs), we carried out molecular screening of 244 blood DNA samples from 20 NWM species from Central and South America. Our aim was to reach a better understanding of their evolutionary processes within the Platyrrhini parvorder. Using PCR amplification with degenerate consensus primers targeting highly conserved amino acid motifs encoded by the herpesvirus DNA polymerase gene, we characterized novel viral sequences from 12 species belonging to seven genera representative of the three NWM families. BLAST searches, pairwise nucleotide and amino acid sequence comparisons, and phylogenetic analyses confirmed that they all belonged to the Cytomegalovirus genus. Previously determined host taxa allowed us to demonstrate a good correlation between the distinct monophyletic clades of viruses and those of the infected primates at the genus level. In addition, the evolutionary branching points that separate NWM CMVs were congruent with the divergence dates of their hosts at the genus level. These results significantly expand our knowledge of the host range of this viral genus and strongly support the occurrence of cospeciation between these viruses and their hosts. In this respect, we propose that NWM CMV DNA polymerase gene sequences may serve as reliable molecular markers with which to infer Platyrrhini phylogenetics.IMPORTANCE Investigating evolutionary processes between viruses and nonhuman primates has led to the discovery of a large number of herpesviruses. No study published so far on primate cytomegaloviruses has extensively studied New World monkeys (NWMs) at the subspecies, species, genus, and family levels. The present study sought to identify cytomegalovirus homologues in NWMs and to decipher their evolutionary relationships. This led us to characterize novel viruses from 12 of the 20 primate species tested, which are representative of the three NWM families. The identification of distinct viruses in these primates not only significantly expands our knowledge of the host range of this viral genus but also sheds light on its evolutionary history. Phylogenetic analyses and molecular dating of the sequences obtained support a virus-host coevolution.
