Abstract
A new gammaherpesvirus, tentatively named cynomys herpesvirus 1 (CynGHV-1), was isolated from a black-tailed prairie dog (Cynomys ludovicianus). CynGHV-1 replicated cytopathogenically to moderate titers in various cell lines. Ten kb of the CynGHV-1 genome was sequenced using degenerate PCR and genomic cloning. Sequence similarities were found to different genes from known gammaherpesviruses. Phylogenetic analysis suggested that CynGHV-1 was in fact a novel virus closely related to representatives of different genera and unclassified members of the subfamily Gammaherpesvirinae. However, CynGHV-1 could not be assigned to any particular genus and therefore remains unclassified.

Figure S1.
Panoramic view alignment of complete pol aminoacid sequences of CynGHV-1 and similar sequences from GenBank obtained by Blast analysis. Alignment positions for which data was available were given a colored background. Sequence positions corresponding to gaps were given a black background (and thus are visualized as black boxes). Sequence positions that are missing (because of disparities in the length of sequences) are indicated with question marks (?) and have no background. (PDF 1333 kb)
Figure S2.
Parsimony tree of complete pol amino acid sequences of CynGHV-1 and similar sequences from GenBank as shown in Fig S1. Numbers on tree nodes indicate bootstrap (n=100) support. Branches with bootstrap supports lower than 50 were collapsed. Maximum Likelihood and Bayesian analyses (not shown) gave similar results. Branch lengths are proportional to the number of amino acid substitutions (bar = 10 substitutions). (TIFF 14080 kb)
