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...

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...
