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...

Genetic Resistance to Porcine Reproductive Respiratory Syndrome Virus (PRRSV)
February 10, 2004By Rodger K. Johnson
In the experiment pigs of two distinctly different populations were challenged with PRRS virus. The lines differed in physiological responses to virus (body temperature, weight gain, ability to...

PCV-2 viral DNA(s) are Infectious for Gnotobiotic Swine
January 23, 2004By Steven Krakowka
Porcine circovirus type 2 (PCV-2) infection is now recognized to be a common subclinical infection of swine of all ages. Disease expression as postweaning multisystemic wasting syndrome (PMWS) is...

Effect of Sow Dietary Glutamine Intake on Subsequent Nursery Pig Growth After an Intestinal Disease Challenge
November 17, 2003By Philip S. Miller
The data from this experiment suggest that increased sow consumption of glutamine does not improve the immune response of endotoxin-treated progeny following weaning. However, it appears that...

Evaluation of a Chlorate Treatment on Post-Weaning Diarrhea Caused by E. Coli in Weaned Pigs
September 15, 2003By Tom S. Edrington PhD
In a series of five experiments, we evaluated the effect of chlorate on reducing gut populations of the E. coli capable of causing post-weaning diarrhea. In three of the experiments, we had a model...
