Key result
The causative agent of duck beak atrophy and dwarfism syndrome (BADS) in Cherry Valley ducks in Chongqing, China, was identified as a novel duck-origin goose parvovirus (DGPV).
Why the study?
An unidentified disease causing short beak and growth retardation occurred in Cherry Valley ducks, prompting an investigation to identify the causative agent of beak atrophy and dwarfism syndrome.
Observational
The study identifies a novel duck-origin goose parvovirus as the causative agent of duck beak atrophy and dwarfism syndrome in China.
Hypothesis-generating for DGPV in emerging duck syndromes; leaves open surveillance needs and cross-species risks in waterfowl.
Duck beak atrophy and dwarfism syndrome (BADS) is a newly emerged disease in China since 2015. In October 2017, an unidentified disease occurred in Cherry Valley ducks, Chongqing municipality, the southwest of China. The affected birds showed short beak and growth retardation clinical signs. The disease caused approximately 20.00% morbidity and serious weight loss due to retarded growth. In order to identify the causative agent of BADS, liver, spleen, lung and heart samples were collected for virus isolation, hemagglutination test, PCR identification, and partial gene sequencing. The isolated virus was tentatively named SC16. Hemagglutination test indicated that the virus was negative to chicken red blood cells. Based on the PCR and sequencing results, the causative agent of BADS was a novel duck-origin goose parvovirus (DGPV) while no another co-infection pathogen was found in this case. Further analysis could provide insights into the control strategies of DGPV in ducks.
