Swine Health - PRRS
Sampling of adult boars during early infection using a new serum collection technique for PRRS PCR testing prior to semen collection
April 1, 2005By Darwin L. Reicks
In the study, serum had a higher quantity of virus than the blood swab samples as expected. The blood swab method can be done on boars each collection day, thus is user-friendly when compared with...

A prospective observational study of periparturient sow mortality
February 11, 2005By John Deen
In this study, as well as others, it has been shown that the probability of dying is seven times as high during the period from day 111 of gestation to weaning (approximately 21 days) as compared to...

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...

The immunological significance of PRRS virus genetic variation
February 4, 2005By Kyoung-Jin Yoon
A high rate of genetic and antigenic variability is known to exist among PRRS viruses and has garnered great attention from the swine industry since such a phenotypic variation is perceived to...

A novel PRRS vaccine in a bacterial vector known to stimulate strong cell-mediated and humoral immunity
November 5, 2004By MVSc|PhD|Ramesh Vemulapalli BVSc&AH
The results of this research project suggest that, despite several unique, advantageous properties, Brucella abortus RB51 is not very useful for developing effective recombinant PRRS vaccines.

Efficacy of Multiplex SIV TaqMan? RT-PCR and PRDC Microarray Hybridization in Predicting Swine Influenza Virus Genotype
November 1, 2004By Kay S. Faaberg
New Multiplex TaqMan? RT-PCR genotyping assays for HA and NA genes of SIV were developed. These new diagnostic tests will advance available SIV diagnostics, both in speed and accuracy. We found that...

Protective Immunity against Porcine Reproductive and Respiratory Syndrome Virus (PRRSV)Obtained by Passive Administration of Antibodies: Optimization of the Conditions
October 7, 2004By Fernando Osorio
Neutralizing antibodies are those antibodies produced by a pig infected with PRRSV which, when mixed with PRRSV in a test tube, render it uninfectious by inactivation. Based on the results of...

The influence of maternal antibody against porcine reproductive and respiratory syndrome virus (PRRSV) infection and the effect of a killed PRRSV vaccine in increasing the level of maternal antibody
October 7, 2004By Eileen Thacker
PRRSV-positive sow herds can produce PRRSV-negative pigs. This phenomenon is important in herd stabilization against PRRSV-induced disease. One possible explanation of this phenomenon would be that...

Clostridium difficile as a Cause of Enteritis in Neonatal Pigs
October 5, 2004By J. Glenn Songer
Strains of C. difficile from piglets are quite uniform genetically, which suggests that a single immunoprophylactic product, when developed, will be effective across the industry. Furthermore, the...

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...
