The study on the molecular characteristics and variation patterns of the recombinant Muscovy duck parvovirus strain GD-23.

As the virus continues to spread, the frequency of contact between different parvovirus strains has increased. In recent years, recombinant Muscovy duck parvovirus (rMDPV) has been widely prevalent in China. In 2023, a strain of rMDPV, designated GD-23, was isolated from Guangdong.

Synergistic pathogenicity of novel duck Orthoreovirus and salmonella typhimurium in ducks.

Co-infection with Novel Duck Orthoreovirus (N-DRV) and Salmonella Typhimurium (S. Typhimurium) poses significant threats to duck health. The disease associated with N-DRV is characterized by epizootic outbreaks featuring hepatosplenomegaly, hemorrhage, and necrosis.
