Designing PRRSV Vaccines for Heterologous Protection Dr. X.J. Meng, VA-MD College of Veterinary Medicine, Virginia Tech, looks at designing Porcine Reproductive and Respiratory Syndrome Virus (PRRSv) vaccine for heterologous protection. Dr. Meng states that PRRS remains a major problem to the global swine industry. Dr. Meng also mentions there is an emergence of new and more virulent PRRSv strains, like “porcine high fever disease” caused by a highly pathogenic PRRSv. A conclusion from developing a PRRSv vaccine: DNA shuffling offers an opportunity for rational design of PRRSv MLV vaccines that confer heterologous protection [video].
Genetics of Host Resistance to PRRS and PCV2 Dr. Jack Dekkers, Iowa State University, presents information around the genetics of host resistance to Porcine Reproductive and Respiratory Syndrome Virus (PRRSv) and Porcine Circovirus Type 2 (PCV2). Dr. Dekkers presents data and research to use genomics to identify genes / genomic regions associated with resistance / susceptibility to PRRS virus infection. Some take aways: Vaccination-co-infection design is good model for PCVAD; and PRRS and PCV2b viremia controlled by different genomic regions with versus without vaccination [video].

Antibiotic Stewardship Human and animal health experts came together in Atlanta, GA to discuss issues related to antibiotic resistance and to work toward increased antibiotic stewardship, in both human medicine and animal health. Throughout the dialogue, attention was focused on specific areas which can be measured in order to verify the progress made in reducing antimicrobial resistance.
Convened by the National Institute for Animal Agriculture (NIAA) and supported by several industry stakeholders, commodity groups, and public health entities, this national symposium brought together a broad cross-section of professionals to share relevant science and develop consensus on those key areas in which the most progress may be made [Conference Connection].
