Chicken infectious anemia virus
Chicken infectious anemia virus (CIAV) is a spherical, non-enveloped, single-stranded virus that is a member of the Circoviridae family of viruses. This family contains two genera, Circovirus and Gyrovirus. CIAV is a type of Gyrovirus which has only been found to affect chickens.
CIAV causes the disease called chicken infectious anemia, which is associated with the depletion of cortical thymocytes and erythroblastoid cells in the chicken's bone marrow.
