A Case Report of Avian Polyomavirus Infection in a Blue Fronted Parrot (Amazona aestiva) Associated with Anemia

Abstract

An adult Blue Fronted Amazon parrot (A. aestiva) presenting with emesis, apathy, undigested seed in feces, and severe anemia was treated for approximately 2 months. Upon radiographic examination, an enlarged kidney was the only alteration. PCR for avianBornavirus,Circovirus, and Polyomavirus was performed for the feces and blood. The results were positive for APV in both samples and negative for the other viruses. After 6 months, the feces from the same animal were negative for APV. Because the animal was positive for APV in both the feces and the blood, it is likely that these clinical symptoms were due to Polyomavirus infection. Severe anemia is an unusual clinical sign of Polyomavirus, and this study aims to identify novel differential diagnostic criteria for the disease.

First detection and molecular characterization of avian polyomavirus in young parrots in Pakistan

“…The Avian Polyomavirus is a highly infectious psittacine virus, reaching almost 100% infection rates in indoor aviaries (Philadelpho et al 2015). The disease has been described in USA (Dolz et al 2013;Varsani et al 2015), Europe (Johne et al 2006), South Africa (Tajbhai et al 2004), Asia (Ogawa et al 2006;Zhuang et al 2012), New Zealand (Tajbhai et al 2004) and Australia (Hulbert et al 2015).…”

<b>Caracterização molecular de bornavírus, poliomavírus e circovírus em aves de cativeiro, vida livre e criação comercial</b>

“…Apesar da distribuição mundial do vírus (ENDERS et al, 1997;PHALEN et al, 2000;BERT et al, 2005;WOLFF et al, 2006;DEB et al, 2010;ZHUANG et al, 2012;ALLEY et al, 2013;BENNETT;GILLETT, 2014), pouco se estudou sobre ele no Brasil (PHILADELPHO et al, 2015). O APV é comumente descrito em psitacídeos, entretanto, pode ocorrer em passeriformes também (GARCIA et al, 1993;ALLEY et al, 2013), apesar de ser menos descrito.…”
