Global Gene Expression Profiling of PRRSV-infected Alveolar Macrophages
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
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...

Analysis of prevalent environmental conditions in cases of suspected PRRSV lateral transmission between pig farms
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.
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...

Implementation of a PRRSV Strain Database (Renewal)
The PRRSV strain database (http://prrsv.ahc.umn.edu) has been supported by the National Pork Board for three years. The database (PRRSVdb; 7,627 unique sequences) is freely available for web-based...

Enhancement of efficacy of PRRSV vaccines by altering the glycosylation pattern of viral glycoproteins
In previous studies, we have demonstrated that virus-neutralizing antibodies are important for protective immunity against PRRSV. These neutralizing antibodies constitute a significant correlate for...

Elimination of PRRS virus from two regions in Minnesota
This project is an attempt to eliminate PRRS virus from all sites having pigs within two defined regions in Minnesota; eastern Rice county and Stevens County. We have completed our fourth year and...

A study on the feasibility of using a porcine alveolar macrophage cell line to produce a PRRS modified live virus vaccine
The goals of this project was: 1) to determine the feasibility of using an innovative porcine alveolar macrophage cell line, designated ZMAC-1, for the production of a PRRS modified live virus (MLV)...
