The Duck circovirus (DuCV) is a type of virus found in ducks. Strains of the virus have predominantly been found in China, though strains have also been isolated from ducks in Germany and the United States.
Contents
Duck circovirus is a small nonenveloped virus with a monomeric single-stranded circular DNA genome. DuCV has been clustered in the Circoviridae family genus Circovirus, according to the eighth report of the International Committee on Taxonomy of Viruses.
Pathogenicity
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.
Transmission
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.
Symptoms
The symptoms are immunosuppression, stunting in growth, and also feather abnormalities.
Research
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.
Type of Ducks Affected
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.
Prevention
A vaccination against Duck circovirus has not been found. Researchers are still actively trying to find a vaccine.
