Characterization of the genomic sequence of a circo-like virus and of three chaphamaparvoviruses detected in mute swan ( Cygnus olor ).

We report the complete genomes of four ssDNA viruses: a circular replication-associated protein-encoding single-stranded DNA virus belonging to a clade previously detected only in mammals, and three chaphamaparvoviruses, which were detected by viromic surveillance of mute swan ( Cygnus olor ) fecal samples from the United Kingdom.
