Swine Health - PRRS
Identification of a peptide sequence in nsp2 that can function as a deletion marker for the differentiation of vaccinated from naturally infected pigs
May 27, 2008By Raymond R. Rowland
The implementation of an effective control plan for PRRS will require safe and effective vaccines. Future modified live virus (MLV) vaccines will require a mechanism that can be used to 1) identify...

Development of stable cell lines permissive for PRRSV replication and production
May 23, 2008By Dongwan Yoo
PRRS virus (PRRSV) infects only a specific line of simian cells in culture for productive infection. The use of these cells for vaccine development is patent-protected, which severely hampers the...

Characterizing level of PCV type 2 virus in serum and expression of PMWS in different populations of pigs
May 19, 2008By Rodger Johnson
Selection for resistance to PCV2 virus is possible. It can be accomplished by serially scoring pigs for symptoms of PCVAD from 60 to 125 d of age, weighing pigs at these ages, and measuring serum...

In vivo evaluation of genetic markers in the nsp2 region of PRRSV: Implications for future recombinant marker vaccine development
May 15, 2008By Ying Fang
Porcine reproductive and respiratory syndrome (PRRS) virus (PRRSV) continues to be a major problem to the pork industry worldwide. The limitations offered by current PRRSV vaccines require the...

Global Gene Expression Profiling of PRRSV-infected Alveolar Macrophages
April 30, 2008By John Neill
This study examined the effect of porcine reproductive and respiratory virus (PRRSV) on how genes are expressed in porcine alveolar macrophages (PAMs). PAMs were chosen for this study because they...

Evaluation of a new etiological agent of PMWS/PDNS in conventional pigs
March 25, 2008By Gregory W. Stevenson
Porcine circovirus-associated disease (PCVAD) is considered a multifactorial disease since a variety of cofactors, including infectious agents, seem to be necessary for full expression of clinical...

PRRSV infection of pig macrophages
February 19, 2008By William Cafruny
A. Objectives. The objective of this small grant were to was to investigate the regulation of PRRSV infection in cultured pig macrophages. The purpose of the work was to learn more about how PRRSV...

Analysis of prevalent environmental conditions in cases of suspected PRRSV lateral transmission between pig farms
January 4, 2008By Robert Morrison
It is not uncommon for swine herds to become infected with PRRS virus with no obvious source of the infection. In such cases, the producer and veterinarian having explored all possible routes of...

The “Kansas Cluster” of severe PMWS cases: characterization of a novel PCV2 as the possible etiological agent.
October 31, 2007By Raymond R. Rowland
The proposal was submitted in response to a request for proposals to investigate PCV2 associated disease. The three objectives were (1) analyze PCV2 genetic sequences from herds experiencing an...
