The Duck circovirus (DuCV) is a type of virus found in ducks. Strains of the virus have predominantly been found in China,[1] though strains have also been isolated from ducks in Germany[2] and the United States.[3]

Duck circovirus is a small nonenveloped virus with a monomeric single-stranded circular DNA genome.[2][4] DuCV has been clustered in the Circoviridae family genus Circovirus, according to the eighth report of the International Committee on Taxonomy of Viruses.[4]

Pathogenicity[edit]

Scientists have studied the Duck circovirus by using polymerase chain reaction (PCR)-based methods and dot blot hybridisation (DBH) tests. Infection with DuCV appears to cause growth disorders in ducks as well as eventual immunosuppression due to depletion of lymphatic cells.[5]

Transmission[edit]

It was found that ducks between the ages of 40∼60 days were more susceptible to Duck circovirus. There was no evidence showing that the DuCV virus was capable of vertical transmission.[6]

Symptoms[edit]

The symptoms are immunosuppression, stunting in growth, and also feather abnormalities.

Research[edit]

The PCR and dot blot hybridization (DBH) test was used in 2006–2007. 742 ducks from 70 duck farms were tested. The overall infection rate was 33.29%. Ducks at 3–4 weeks of age where more susceptible to DuCV virus.[5]

Type of Ducks Affected[edit]

Anas platyrhynchos, Cairina moschata, and the American Pekin Duck are the ducks most affected by the DuCV virus. These ducks come from various regions of the world.[5]

Prevention[edit]

A vaccination against Duck circovirus has not been found.[4] Researchers are still actively trying to find a vaccine.[citation needed]
