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...

Assessment of the infectivity of asymptomatic carriers, to understand the dynamics of Mycoplasma hyopneumoniae infection in reproductive herds
October 31, 2006By Carlos Pijoan
Designing disease control and/or eradication protocols depends mostly in how much we know about the pathogen we want to eliminate. Regarding Mycoplasma hyopneumoniae, the causative agent of Enzootic...

Accurate ELISA test development: Evaluation of cysteine protease domain of non-structural protein 2 as a potential antigen
October 31, 2006By Ying Fang
Currently, in the absence of effective vaccines and therapeutic drugs, one of the key approaches to achieve the “National PRRS Elimination” is to identify PRRSV infected pigs, so such...

An Improved Method for PRRSV Surveillance and Monitoring
October 11, 2006By Jeffrey Zimmerman
Oral fluids are inexpensive to collect. Each pen sample requires a length of cotton rope, a plastic bag, and a snap-cap plastic tube. Labor costs include the time required to place and recover the...
