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...

Real-time PCR detection of PRRSv and rapid identification of vaccine in serum and semen
July 28, 2004By Dr. Richard Oberst
The detection of PRRSv in boars is critical for developing and maintaining a biosecure breeding program, however it is complicated by many variables. Correlating the current PRRSv infectious status...

Immunomodulation of humoral immunity in PRRSV-infected piglets
July 7, 2004By John Butler
PRRS is caused by a virus that causes the host's immune system to malfunction much in the same manner in which infectious agents can trigger the onset of autoimmune syndromes like Lupus or rheumatoid...

Environmental Factors that Induce the Expression of Receptors for F18+ Enterotoxigenic Escherichia coli
June 30, 2004By David Francis
This study was conducted to determine why pigs become highly susceptible to F18+ enterotoxigenic E. coli shortly after weaning. It was suspected that the change in susceptibility was triggered by...

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,...

Development of an Antiviral and Vaccine Approach to Control Foot-and-Mouth Disease
June 15, 2004By Marvin J. Grubman
Foot-and-mouth disease virus (FMDV) causes a highly contagious disease of cloven-hoofed animals including swine, cattle, sheep and goats. The economic impact of an FMD outbreak can be devastating as...

Characterization of West Nile Virus Infection in Swine
May 9, 2004By K. B. Platt DVM|Professor of Veterinary Microbiology
West Nile virus (WNV) infects weanling pigs. These infections appear to be mostly inapparent but can result in a reduction of weight gain during the time that WNV is found in the blood. The lesions...

Genomic Quasispecies Associated with the Persistence of PRRS Virus
March 26, 2004By David Benfield
What is the significance of these results for producers? First, the most likely primary site for replication of the PRRS virus is lymphoid tissue, either tonsil and/or lymph nodes. The early...

Assessment of Mycoplasma hyopneumoniae strain variability and relationship to virulence
February 26, 2004By F. Chris Minion
Mycoplasma hyopneumoniae isolated from different pig herds showed variation in disease potential. This is not unexpected since differences in disease symptoms occur widely in the field. There have...
