Mechanism of Antibody-Mediated Neutralization of PRRSV
One of the challenges in developing effective vaccines for PRRSV is the limited understanding of how neutralizing antibody inhibits PRRSV replication, and how variation in PRRSV leads to escape from...

Epitope Inclusion: Enhancing porcine reproductive and respiratory syndrome virus (PRRSv) vaccine cross-protective efficacy
Producers need better vaccines for controlling disease and spread associated with PRRSv infection. This has been an extremely different task because the face of PRRSv is constantly changing making an...

Evaluation of dietary soybean meal replacement on grow-finisher pig performance when challenged with PRRS and Mycoplasma
The amino acids requirements of growing-finishing pigs are met by utilizing a variety of protein rich ingredients, including soybean meal (SBM) and distillers dried grains with solubles, as well as...

Evaluating nutritional strategies to mitigate the negative impact PRRS has on grow-finisher pig performance
Of the health challenges the swine industry face, Porcine Reproductive and Respiratory Syndrome (PRRS) virus is arguably one of the most economically costly viruses to U.S. and world pork production....

Characterization of high passages of an interferon-inducing PRRSV strain
As stated in the contract, we require an industry summary of the project, suitable for immediate public release by the Board. The purpose of the industry summary is to provide producers...

Determination of the PRRSV minor glycoproteins contribution to antigenicity and protection
Porcine reproductive and respiratory syndrome virus (PRRSV) has been the most significant disease affecting swine in the U.S. for decades. Contemporary epidemiological methods rely on sequencing of...

Development of a Novel Self-Propagating PRSSV-VSV G Hybrid Replicon as a Vector for Inducing Broad PRRSV Protection
Throughout successive cycles of Pork Check-off funding, our laboratories (Pattnaik’s and Osorio’s labs) have consistently produced new and fundamental information on: (i) the...

Development of on-farm PRRSV surveillance guidelines for the modern pork industry
Oral fluids (OF) are a convenient surveillance sample because they (1) are easily collected by a single person; (2) can be collected frequently without stress to pigs or people; and (3) provide...

The effect of PRRSv infection on the thymus – a source of immune dysregulation?
PRRSv infection has been shown to cause an acute lymphopenia (loss of cells in the blood), lymphadenopathy (increased size of lymph nodes due to increased cell numbers) and thymic atrophy (decreased...

Use of interferon alpha as an immunomodulator and metaphylactic therapeutic during PRRSV outbreaks
The host response to virus infection begins almost immediately with recognition of virus by host cells leading to the production of antiviral substances such as interferons. One interferon,...

Development of next generation sequencing methodology for full genome characterization of porcine reproductive and respiratory syndrome virus (PRRSV) from oral fluids and nasal swabs
Porcine reproductive and respiratory syndrome virus (PRRSV) is one of the most significant swine diseases with near worldwide distribution. In the U.S., open reading frame 5 (ORF5) is commonly...
