Determination of the importance of porcine parvovirus type 2 (PPV2) in porcine circovirus associated disease (PCVAD) outbreaks by elimination of PPV2 through vaccination at weaning
December 2, 2016
Despite widespread porcine circovirus type 2 (PCV2) vaccination in the growing pig population, occurrence of porcine circovirus associated disease (PCVAD) can be observed particularly in larger...Determination of the virulence of an emerging porcine parvovirus (PPV2) and its possible interaction with PCV2 in PCVAD
April 26, 2016
The objective of this study was to characterize a novel PPV previously designated as PPV2 in pigs and to determine the interaction of PPV2 and PCV2. Colostrum-deprived pigs experimentally infected...Characterization of emerging porcine parvovirus types in the U.S. pig population
July 21, 2014
A new porcine parvovirus (PPV), provisionally designated asPPV5, was identified in U.S. pigs. PPV5 is most closely related to PPV4 with overall genomic...Determination of the virulence of a mutant PCV2 (PCV2d) recently identified in cases of apparent vaccine failure and the ability of commercial PCV2a vaccines to protect against PCV2d
July 4, 2014
PCV2d (formerly known as mutant or mPCV2) emerged in the U.S. in 2012 and important questions on virulence of this novel strain and vaccine protection by currently used vaccines needed to be...Characterization of porcine astrovirus infection in the U.S. pig population
February 16, 2014
Many astrovirus (AstV) species are associated with enteric disease. In this study, the prevalence rates of porcine AstV types 1–5 (PAstV1–PAstV5) in the U.S. pig population were...Comparison of PCR and serological assays for reliable, early and fast detection of PRRSV in boar studs
December 16, 2012
The high economic impact of porcine reproductive and respiratory syndrome virus (PRRSV) dictates the need for rapid and accurate diagnosis. The high mutation rate, rapid evolution and genetic...Monitoring of a bacterial infection (Erysipelothrix rhusiopathiae) via oral fluid testing
August 9, 2012
Swine erysipelas, when uncontrolled, is an economically important disease caused by Erysipelothrix rhusiopathiae. Pen-based collection of oral fluids has recently been successfully utilized for...Characterization of emerging porcine parvovirus types in the U.S. pig population
August 9, 2012
Recent evidence suggests that changes are occurring with porcine parvovirus (PPV). New strains of paroviruses have been identified in pigs in some parts of the world and questions are being asked...Comparison of the efficacy of vaccines based on subtype PCV2a or PCV2b in their ability to protect against PCV2b or PCV2a/b challenge
June 27, 2012
Essentially all of the current commercial porcine circovirus type 2 (PCV2) vaccines are based on genotype 2a (PCV2a) and are effective in protecting against PCV2b challenge which is the current...
