Genomes of cressdnaviruses, microviruses, a gyrovirus, and a caudovirus identified in the fecal samples of a mallard and double-crested cormorant.

Mallards and double-crested cormorants have a broad distribution across North America. In the fecal sample from two individual mallard and double-crested cormorant, we determined the genomes of a caudovirus, microviruses ( n = 6), cressdnaviruses ( n = 35), and a gyrovirus (chicken anemia virus, CAV). Here, we report double-crested cormorant as a CAV host.
