Complete genome sequence of cercopithecine herpesvirus 2 (SA8) and comparison with other simplexviruses.
We have obtained the complete sequence of the herpesvirus simian agent 8 (SA8; cercopithecine herpesvirus 2) a baboon simplexvirus closely related to the monkey B virus and herpes simplex virus types 1 and 2. The genome of SA8 is 150,715 bp long, with an overall G/C content of 76%, the highest among the simplexviruses sequenced so far. The sequencing has confirmed that the genomic arrangement of SA8 is similar to that of other simplexviruses: unique long and unique short regions bordered by two sets of inverted repeats. All genes identified in SA8 are homologous and collinear with those of the monkey B virus, including the lack of the RL1 open reading frame, a gene responsible for neurovirulence in human herpes simplex viruses. This latter finding supports the hypothesis that a different pathogenetic mechanism may have developed in human simplexviruses, after their divergence from monkey simplexviruses.[1]References
