Study reports first detection of Influenza D Virus in French fattening pigs with genetic data on the swine strain.
- Influenza D virus (IDV) was detected in fattening pigs in France, with the genetic data of the swine origin strain provided.
- The IDV strain from the pigs was found to be a reassortant strain, reflecting transmission from bovines to swine.
- Serologic data indicated that IDV spread within the pig herd, including possibly among piglets and farrowing sows.
- Unique mutations in the hemagglutinin-esterase fusion protein of the IDV strain may have facilitated adaptation to the pig host.
- The findings suggest that IDV can be transmitted from bovines to swine and highlight the importance of surveillance for IDV in animal health.
