Facilitating the U.S. Swine Health Improvement Plan Feed Biosecurity Working Group
March 30, 2025By Jordan T. Gebhardt
The objective of this project was to determine appropriate application of best practices for responsible import of feed and ingredients from ASF/CSF affected countries and to develop industry standards for feed biosecurity that can be rapidly implemented across the swine and feed industry in the event that ASFV or CSFV enters the US domestic and/or feral swine population.

Systematic Discovery of ASFV Determinants of Virulence to Improve the Safety Profile of First Generation Live-Attenuated ASFV Vaccines
March 15, 2024By Douglas Gladue
In this study we aimed to identify proteins in ASFV using serum containing antibodies from animals with live-attenuated vaccinated animals, that could be used as targets for a serological assay to differentiate between vaccinated and infected animals, these identified proteins were attempted to be deleted from a field isolate of highly pathogenic ASFV, to determine if they could be deleted.
