Herpesviridae

A second clade includes the alpha- and delta-like viral Pol from insect ascovirus (Ascoviridae), mammalian herpesviruses (Herpesviridae), fish lymphocystis disease virus (Iridoviridae) and chlorella virus (Phycoviridae).

Some have circular genomes (Baculoviridae, Papovaviridae and Polydnaviridae) while others have linear genomes (Adenoviridae, Herpesviridae and some phages).

Some viral infections can also be latent, examples of latent viral infections are any of those from the Herpesviridae family.

The pol genes of the African swine fever virus (Asfarviridae), baculoviruses (Baculoviridae), fish herpesvirus (Herpesviridae), T-even bacteriophages (Myoviridae) and poxviruses (Poxviridae) were not clearly resolved.
