Mechanisms of Failed Protection Against PRRS in Sow Herds
February 28, 2007By Michael Murtaugh
We have established a set of standard protocols and reagents for whole genome PRRSV sequencing and assembly. Phylogenetic comparisons amongst 10 pairs of homologous strains confirmed several regions...

Evaluation of diagnostic assays for Mycoplasma hyopneumoniae: Their potential role in eradication success
February 20, 2007By Eileen Thacker
Respiratory disease induced by Mycoplasma hyopneumoniae (Mhyo) is a problem recognized by the swine industry world-wide. Due to the significant production costs associated with Mhyo-induced...

Investigation into the ability of the anti-idiotype to block PRRS virus infection and characterization of a putative receptor on MARC-145 cells and porcine alveolar macrophages
November 25, 2006By Jeffrey Zimmerman
PRRS is the most costly disease U.S. swine producers confront and little progress has been made in recent years to improve the situation. Prevention and control of PRRS has been difficult, in part...

Implementation of a PRRSV Strain Database (Renewal)
November 7, 2006By Kay S. Faaberg
A PRRSV ORF5 database, accessible worldwide, was improved for swine producers, practitioners and researchers (http://prrsv.ahc.umn.edu/). This database, established to fulfill one objective of the...

ub-typing of PRRSV isolates by means of measurement of cross-neutralization reactions
November 3, 2006By Fernando Osorio
One of the major obstacles for PRRSV control is the significant variability of this virus in the field. Such variability of PRRSV is expressed at the level of the genetic information of the strains (...

Analyzing PRRS status of piglets on multiple farms after serum exposure to validate production of negative piglets
November 3, 2006By Jeff Feder
Based on these results, serum exposure can be an effective way of stabilizing a sow herd and weaning negative piglets on a consistent basis in large, commercial sow units faced with a variety of PRRS...

Investigating the pathogenicity of pestiviruses or pesti-like viruses isolated from recent swine epidemics
November 1, 2006By Kelly Lager
Bovine viral diarrhea virus (BVDV) is a virus usually found in domestic and wild ruminants. However, a BVDV was recently isolated from a case of severe mortality (about 55%) in finishing swine. This...

Development and Optimization of a Blocking ELISA for Type 1 and Type 2 Strains of Porcine Reproductive and Respiratory Syndrome Virus
November 1, 2006By Christopher Chase
The NPB Initiative recognizes that the most effective way to control PRRS is to eliminate the virus from domestic swine herds. Control and elimination strategies should include diagnostic tools that...
