Studying Porcine Epidemic Diarrhea Virus

Update on Porcine Epidemic Diarrhea Virus StudiesUnderstanding on PEDV Dr. Dane Goede and Dr. Bob Morrison provide an update on the ongoing Porcine Epidemic Diarrhea Virus (PEDV) research studies at the University of Minnesota. They look at production impact and share information about the Swine Health Monitoring Project.

Swine Influenza: Management and Challenges

Management and challenges of dealing with swine influenzaChallenges of Swine Influenza Dr. Dyneah Classen presents on the challenges of surveillance and management of swine influenza. Dr. Classen details several of the protocols that should be done for surveillance. Surveillance data is needed to help determine farm vaccination strategies. Dr. Classen concludes with observations that vaccination of the entire breeding herd can reduce viral shedding in both sows and suckling piglets plus suckling piglets may be a source of virus to other pigs.

Mr. Diaz suggested that wean pigs can be a source of influenza A virus to other swine populations and that the maternal immunity does not protect weaned pigs from influenza A virus infection but it did reduce transmission.
