| butcherbird polyomavirus isolated from a grey butcherbird (cracticus torquatus) in queensland, australia. | a novel avian polyomavirus was detected in peri-ocular skin lesions collected from a grey butcherbird (cracticus torquatus), using a combination of multiply primed rolling circle amplification, nested pcr and long range pcr. the sequence of butcherbird polyomavirus was determined by combining next generation sequencing and primer walking techniques. the circular double-stranded dna genome of butcherbird polyomavirus consisted of 5084 bp, and encoded six open reading frames (orf-x, vp2, vp3, vp1, ... | 2014 | 24355535 |
| serological cross-reactions between four polyomaviruses of birds using virus-like particles expressed in yeast. | polyomaviruses are aetiological agents of fatal acute diseases in various bird species. genomic analysis revealed that avian polyomavirus (apyv), crow polyomavirus (cpyv), finch polyomavirus (fpyv) and goose hemorrhagic polyomavirus (ghpyv) are closely related to each other, but nevertheless form separate viral species; however, their serological relationship was previously unknown. as only apyv can be grown efficiently in tissue culture, virus-like particles (vlps) were generated by expression ... | 2012 | 22933666 |
| characterization of two novel polyomaviruses of birds by using multiply primed rolling-circle amplification of their genomes. | polyomaviruses are small nonenveloped particles with a circular double-stranded genome, approximately 5 kbp in size. the mammalian polyomaviruses mainly cause persistent subclinical infections in their natural nonimmunocompromised hosts. in contrast, the polyomaviruses of birds--avian polyomavirus (apv) and goose hemorrhagic polyomavirus (ghpv)--are the primary agents of acute and chronic disease with high mortality rates in young birds. screening of field samples of diseased birds by consensus ... | 2006 | 16537620 |
