AI Technical Summary
Existing technologies are unable to effectively control duck diseases caused by duck short-beaked dwarf syndrome virus, resulting in high morbidity and mortality rates and causing economic losses to the duck farming industry.
By continuously passaged the duck short-beaked dwarf syndrome virus (SBDSV) M15 strain in Muscovy duck embryo fibroblasts, the SBDSV MA strain, which has good safety, stable genetic traits, and strong immunogenicity, was obtained and applied to live vaccines.
The obtained SBDSV MA strain was used to prepare a live vaccine that can effectively prevent duck short-beaked dwarf syndrome virus disease, reduce morbidity and mortality, protect the health of duck flocks, and meet the requirements for preparing attenuated live vaccines.
