Abstract

Avian polyomavirus can infect multiple bird species and cause inflammatory disease with high mortality in young psittacine birds. In this study, we sequenced and analyzed an avian polyomavirus isolated from a pigeon in China, strain APV-P, which is closely related to a polyomavirus in psittacine birds.

Highlights

  • Avian polyomavirus can infect multiple bird species and cause inflammatory disease with high mortality in young psittacine birds

  • Frame (ORF) is located within the VP2 ORF, and the amino acid sequence of VP3 is identical to the sequence of the C terminus (235 aa) of VP2

  • The VP4Delta protein shares the same amino acid sequence with VP4 except it is truncated between amino acids 68 and 131

Summary

Introduction

Avian polyomavirus can infect multiple bird species and cause inflammatory disease with high mortality in young psittacine birds. The genome of the APV-P isolate was found to be circular and 4,981 bp in length, with 49% GC content. The genome structure of the APV-P isolate is similar to those of avian polyomaviruses and contains a noncoding control region (NCCR) and early and late regions.
