Abstract excerpt
Evolutionary studies on the recently discovered TT virus (TTV) are currently focused on approximately 220 nts of the N22 region, since this is the region for which most sequence information is available. Regarding the extensive sequence heterogeneity in this region, within group classification can be sufficiently reliable, however, between group classification becomes problematic. We observed high divergence at...
