Expanding the immune toolkit for assessing pig health and improving swine disease and vaccine studies
May 8, 2007By Joan K. Lunney
Swine disease and vaccine research will be advanced by the development of sophisticated tools to measure swine antibodies or immunoglobulins (Igs). Swine produce antibodies, or Igs, in response to...

Development of cost-efficient herd testing protocols based on testing of pooled samples using ELISA
April 2, 2007By Claudia Munoz-Zanai
The objective of this study was to evaluate the feasibility of using pooled serum samples for detection of PRRSV-infected sow herds by ELISA. In order to achieve this objective, 113 true positive...

Pilot surveillance system for emerging diseases in swine-
November 15, 2006By Peter Davies
Regional spread of PRRS and other swine diseases continues to place a major burden on North American swine producers. Advances in computers and communications technology are creating new...

Development and Optimization of a Blocking ELISA for Type 1 and Type 2 Strains of Porcine Reproductive and Respiratory Syndrome Virus
November 1, 2006By Christopher Chase
The NPB Initiative recognizes that the most effective way to control PRRS is to eliminate the virus from domestic swine herds. Control and elimination strategies should include diagnostic tools that...

Accurate ELISA test development: Evaluation of cysteine protease domain of non-structural protein 2 as a potential antigen
October 31, 2006By Ying Fang
Currently, in the absence of effective vaccines and therapeutic drugs, one of the key approaches to achieve the “National PRRS Elimination” is to identify PRRSV infected pigs, so such...

The role of downtime in pathogen contamination of swine facilities
October 9, 2006By Dr. Sandra Amass
The effectiveness of decontamination procedures and downtimes in reducing PRRSV and bacterial contamination of wean-finish and nursery rooms of a commercial swine farm was tested. The herd was...

PCR-on-a-Chip for the Identification and Control of Porcine Reproductive and Respiratory Syndrome Virus
August 17, 2006By Sheila Grant PhD
We have been working on the development of a micro-fluidic DNA assay with the goal to quickly identify the introduction of PRRSv in pig herds in order to eliminate the transmission and spread of the...

Macrophage cell-lines for in vitro propagation of porcine reproductive and respiratory syndrome virus
February 9, 2006By Subramaniam Srikumaran
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...

Construction of Dynamic Aerosol Toroid Chambers
January 18, 2006By Jeffrey Zimmerman
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...

Investigation into the Ability of Anti-Idiotypic Antibodies to Protect Pigs from Porcine Reproductive and Respiratory Syndrome Virus
February 10, 2005By En-Min Zhou
PRRS is the most costly disease U.S. swine producers confront and little progress has been made in recent years to improve the situation. Prevention and control of PRRS has been difficult, in part...

Optimization of Methods for the Study of Swine Viral Pathogens in Aerosols
July 30, 2004By Jeffrey Zimmerman
Understanding the routes of PRRSV transmission and doses required to cause infection within and between herds is critical for control and eradication of PRRSV. Aerosol research is dynamic and...

Development of Real-time, multiplex PCR/RT-PCR assays for improved PRDC pathogen detection
June 28, 2004By Steven B. Kleiboeker
A number of pathogens (both viruses and bacteria) cause respiratory disease in swine. Often the clinical signs of disease are similar for infected pigs. Therefore to accurately diagnose the cause,...
