Ultrastructural Identification of Circovirus in the Liver of Saffron Finch (Sicalis flaveola spp.)

Circovirus are viral agents that cause disease in avian species. The main clinical symptoms of the disease are immunosuppression and, in young birds feather disorders. In neonates, the disease is known as "black spot" and characterized by abdominal enlargement, hepatobiliar congestion and...

The main clinical symptoms of the disease are immunosuppression and, in young birds feather disorders. In neonates, the disease is known as "black spot" and characterized by abdominal enlargement, hepatobiliar congestion and failure to thrive.
