Age Susceptibility of Ducks to the Rous Sarcoma Virus and Variation of the Virus in Ducks

This report from SRUC VS highlighted a suspected case of Schmallenberg virus infection in a calf born to an imported heifer, noting consistent clinical signs and seroconversion in the dam.

This study explored the relationships between virus susceptibility to infection and several factors, finding that higher heat tolerance and larger virus size correlated positively with infection susceptibility, while high humidity and higher mutation rates correlated inversely among eight RNA viruses, including SARS-CoV-2 and influenza.

This study found that among eight RNA viruses, susceptibility to infection is directly related to heat tolerance and virus size, while inversely related to high humidity and mutation rate. Additionally, larger viruses had higher mutation rates.

This study found that the Msx2 gene may regulate goose feather follicle development by influencing cell viability and gene expression, with potential implications for improving down production.

In this study, researchers found that pigs with genetically disrupted ANTXR1 were resistant to Senecavirus A infection, showing no clinical symptoms, and provided a model for human GAPO syndrome, while confirming ANTXR1 as a receptor for the virus.
