Genome arrangement of DPyV-1 (accession number: KC594077).

<p>Possible intron in VP2 indicated, containing three in-frame stop codons. Truncation of the VP2 by any of these stop codons considered unlikely as the region downstream of the intron (a) shows strong homology to VP2.</p

Phylogenetic trees based on complete A) early (T Antigen) and B) late (VP1, VP2 and VP3) transcripts.

<p>Alignments were generated using Muscle (executed in Geneious V6.0.4), and Maximum Likelihood trees generated in Mega V.5.</p

There is multifocal attenuation and necrosis of the epithelium and filling of the lumen with debris and sloughed epithelial cells.

<p>Multifocal sloughed cells demonstrate karyomegaly with basophilic intranuclear inclusions (arrows). HE stain at 20× magnification.</p
