Identification of Circovirus Genome in a Chinstrap Penguin ( Pygoscelis antarcticus ) and Adélie Penguin ( Pygoscelis adeliae ) on the Antarctic Peninsula
Circoviruses infect a variety of animal species and have small (~1.8–2.2 kb) circular single-stranded DNA genomes. Recently a penguin circovirus (PenCV) was identified associated with an Adélie Penguin ( Pygoscelis adeliae ) with feather disorder and in the cloacal swabs of three asymptomatic Adélie...
