Prevention of Edema Disease Using a Probiotic Expressing Shiga Toxin 2e Receptor Mimic
Edema disease is a naturally occurring infection of weaned piglets caused by E. coli bacteria that produce Shiga toxin. This toxin is absorbed from the gut into the blood stream and causes the...

Interaction of PRRSV and Porcine Dendritic Cells: Potential Role in Viral Persistence
Porcine reproductive and respiratory syndrome virus (PRRSV) may persist in tissues of pigs for months. How the virus persists in certain pigs remains to be determined. It is possible that a subset of...

Macrophage cell-lines for in vitro propagation of porcine reproductive and respiratory syndrome virus
Vaccination of pigs against PRRSV is the most prudent and logical way of controlling this economically important disease. Production of vaccines requires large scale propagation of PRRSV in the...

Development of a Killed Subunit PRRS Vaccine
The focus of our research funded by the National Pork Board was to develop second generation killed PRRS vaccines. The portion of the PRRS virus responsible for stimulating the neutralizing immune...

Construction of Dynamic Aerosol Toroid Chambers
PRRSV costs the US swine industry 560 million dollars each year in lost productivity. We can now successfully eliminate PRRSV from individual farms, but we cannot keep herds from becoming...

A pilot project to determine the feasibility of controlling PRRS within a selected region
The purpose of this project was to determine if pork producers within a defined region were willing to test their herds for PRRS virus, share the results with other cooperating producers, and share...

Assesment Of Vertical Transmission From Parity One Sows Infected With A Low Dose And Mild Pathogenic Prrsv Isolate
In order to generate a protocol to sample lactating piglets to evaluate PRRSV chronically infected herds twelve PRRSV naïve pregnant sows were individually housed and assigned to three different...

Attempt to transmit swine hepatitis E virus (HEV) by consumption of fresh and frozen pork loin or liver
Hepatitis E virus (HEV) infects pigs but does not cause clinical disease in pigs. There is concern that hepatitis E virus from pigs may infect people and that pigs may be an important reservoir for...

Rational Design of a New Generation of PRRSV Differential (Marker) Vaccines
We started this project with the conviction that the use of vaccines will always be a cost-efficient method and the preferred approach to control PRRSV infections , provided the efficacy and safety...

Evaluation of live vaccine strains of Actinobacillus pleuropneumoniae
Even though improved husbandry has reduced the level of porcine pleuropneumonia caused by Apl, this disease is still a significant problem for the swine industry. Current vaccines do not adequately...
