TL;DR: A 2.4-kb phi29 polymerase amplification product from serum of a diseased chicken was cloned and sequenced, showing limited similarities to a representative genome of chicken anemia virus, and it is proposed that the newly identified virus is a new species in the genus Gyrovirus.

TL;DR: The characterization of the faecal virome of healthy chickens described here not only provides a description of the viruses encountered in such niche but should also represent a baseline for future studies comparing viral populations in healthy and diseased chicken flocks.

TL;DR: Analysis using inverse PCR and Sanger sequencing led to the characterization of four new putative members of the family Circoviridae with genome size ranging from 1,608 to 1,790 nt, two inversely arranged ORFs, and canonical nonamer sequences atop a stem loop.

TL;DR: The findings provide evidence for the possibility of contamination of poultry vaccines with CAV and AGV2 and they also emphasize the need of searching for these agents in vaccines in order to ensure the absence of such potential contaminants.

TL;DR: Evidence is provided thatAGV2 seems fairly distributed in chickens in Southern Brazil and that AGV2 also circulates in the Netherlands, and the occurrence of variants of AGV 2, which may reflect differences in geographical origin and/or in biological properties.
