Swine Health - PRRS
Assessing the use of biofilters and antimicrobial filters to reduce the excretion of PRRS virus into the environment
January 22, 2009By Scott Dee
As area-based PRRSV control and eradication programs move forward, the ability to minimize the risk of PRRSV-excretion into the environment from infected populations becomes important. This study...

Implementation of a PRRSV Strain Database (Renewal of NPB project #06-127)
January 7, 2009By Kay S. Faaberg
The PRRSV strain database (http://prrsvdb.org) has been supported by the National Pork Board for four years. The database (PRRSVdb; 9,531 sequences) is...

Development of Edible Vaccines against PRRSV: A Proof of Concept Study
December 22, 2008By Chenming (Mike) Zhang
The overall objective of this project is to develop edible vaccines to combat the devastating porcine reproductive and respiratory syndrome (PRRS) as an alternative to current MLVs. The goal is to...

Identification of protective epitopes toward developing a vaccine providing broad cross-protection against various PRRS viruses
December 15, 2008By Won-Il Kim
Enormous genetic and antigenic variation impedes effective control and prevention of PRRS. Since PRRS virus vaccination is shown to be effective only against homologous or closely related viruses,...

Induction of Cross-Protective Immunity Without Exposure to Live PRRSV
December 1, 2008By Luis Enjuanes
Explanation of the objectives. The development of more efficacious vaccines was one of the objectives for NPB 2007 funding. The work reported here is focused on the engineering of a...

Inactivation of PRRSV using ultraviolet light
November 11, 2008By Jeffrey Zimmerman
The objective of this study was to calculate the inactivation of PRRSV by dose of UV254 in a “static” (i.e., virus-in-liquid solution) system. This study is the first step in...

The Comparative T-cell Repertoire Response in PRRSV, SIV and PCV2 Infected Piglets
October 13, 2008By John Butler
Viral infection exposes the host immune system to epitopes that are normally recognized by T cells and which leads to both cytotoxic responses against virus-infected cells and to B cells that make...

Development of a simple on-site diagnostic test to detect PRRSV acute infection in boar studs
October 8, 2008By Claudia Munoz-Zanai
Because PRRSV can be transmitted through artificial insemination with semen from infected animals, boar studs are constantly being monitored for the presence of PRRSV. Current monitoring protocols...

B Cell Repertoire Diversification and Class Switch in PRRS
September 26, 2008By John Butler
Successful PRRSV vaccines and vaccination strategies are best employed when the host’s immune response to the pathogen is understood. Since it was generally known that PRRSV caused non-virus...

Porcine Adenovirus 3 Based Vaccine for Porcine Respiratory and Reproductive Syndrome (PRRS).
July 7, 2008By Dr. Suresh K. Tikoo
Porcine reproductive and respiratory syndrome (PRRS) virus imposes devastating effects on swine health and productivity. Vaccination of animals is one way to reduce losses from infectious diseases...
