Isolation and DNA characterization of a simian retrovirus 5 from a Japanese monkey (Macaca fuscata).

Abstract

An SRV-like virus was isolated from a colony-born Japanese monkey. To identify this SRV-like virus, we designed universal primers at regions that were conserved among the reported SRV sequences in the 5'-LTR and the short ORF and we obtained plasmid clones containing the complete gag, prt, pol and env genes. The full-length sequences of the isolate were determined from the plasmids and by direct sequencing. Sequence comparisons and phylogenetic analyses indicated that this SRV-like virus had a sequence identical to the reported 626 bp of SRV-5. In this study, we isolated SRV5/JPN/2005/V1 from a Japanese monkey and characterized the full-length SRV-5 sequence.
