A genome-wide association study of fetal response to type 2 porcine reproductive and respiratory syndrome virus challenge
Download2016-02-05
Plastow, Graham, Ladinig, Andrea, Harding, John, Wang, Zhiquan, Wilkinson, James, Yang, Tianfu
Control of porcine reproductive and respiratory syndrome (PRRS) is economically important for the swine industry worldwide. As current PRRS vaccines do not completely protect against heterologous challenge, alternative means of control, including enhanced genetic resilience, are needed. For...

The emergence of high-throughput genomic data provides new opportunities for genetic analysis. Especially, in terms of genetic improvement of animals, genomic tools provide new tools for animal selection, while still suffering from some statistical issues due to the high-dimension of the genomic...

Genetic and genomic basis of antibody response to porcine reproductive and respiratory syndrome (PRRS) in gilts and sows
Download2016-01-01
Serao, Nick V. L., Kemp, Robert A., Mote, Benny E., Willson, Philip, Harding, John C. S., Bishop, Stephen C., Plastow, Graham S., Dekkers, Jack C. M.
Background:Our recent research showed that antibody response to porcine reproductive and respiratory syn-drome (PRRS), measured as sample-to-positive (S/P) ratio, is highly heritable and has a high genetic correlation with reproductive performance during a PRRS outbreak. Two major quantitative...

Genome wide association studies (GWAS) identify QTL on SSC2 and SSC17 affecting loin peak shear force in crossbred commercial pigs
Download2016-02-22
Miar, Younes, Wang, Zhiquan, Kemp, Robert A., Boddicker, Nicholas, Yang, Tianfu, Plastow, Graham, Zhang, Chunyan, Charagu, Patrick, Bruce, Heather
Of all the meat quality traits, tenderness is considered the most important with regard to eating quality and market value. In this study we have utilised genome wide association studies (GWAS) for peak shear force (PSF) of loin muscle as a measure of tenderness for 1,976 crossbred commercial...

Maternal and fetal predictors of fetal viral load and death in third trimester, type 2 porcine reproductive and respiratory syndrome virus infected pregnant gilts
Download2015-09-25
Wilkinson, Jamie M., Lunney, Joan K., Detmer, Susan E., Ladinig, Andrea, Harding, John C.S., Ashley, Carolyn, Plastow, Graham
Minimal research has focused on understanding mechanisms underlying porcine reproductive and respiratory syndrome virus (PRRSV) induced reproductive failure. We have completed a large-scale project investigating phenotypic and genotypic predictors of reproductive PRRS severity in which numerous...

Pathologic Evaluation of Type 2 PorcineReproductive and Respiratory SyndromeVirus Infection at the Maternal-FetalInterface of Late Gestation Pregnant Gilts
Download2016-03-10
Novakovic, Predrag, Harding, John C. S., Al-Dissi, Ahmad, Ladinig, Andrea, Detmer, Susan E.
The pathogenesis of fetal death caused by porcine reproductive and respiratory syndromevirus (PRRSV) remains unclear. The objective of this study was to improve our understand-ing of the pathogenesis by assessing potential relationships between specific histopatho-logical lesions and PRRSV RNA...

Relationships of CD163 and CD169 positive cell numbers in the endometrium and fetal placenta with type 2 PRRSV RNA concentration in fetal thymus
Download2016-08-05
Novakovic, Predrag, Harding, John C. S., Ladning, Andrea, Al-Dissi, Ahmad N., MacPhee, Daniel J., Detmer, Susan E.
Several routes of porcine reproductive and respiratory virus PRRSV transmission across the porcine diffuse epitheliochorial placentation have been proposed, but none have been proven. The objectives of this study were to investigate associations between numbers of CD163 and CD169 positive...

Transcriptomic and epigenetic profiling of the lung of influenza-infected pigs: A comparison of different birth weight and Susceptibility groups
Download2015-09-22
Harding, John C.S., Foxcroft, George R., Gunvaldsen, Rayna E., Dyck, Michael K., Plastow, Graham S., Detmer, Susan E., Wilkinson, Jamie M., Dixon, Walter T.
Influenza viruses are a common cause of respiratory disease in swine. Infections range in severity from asymptomatic to causing significant morbidity. The main objective of this study was to compare lung transcriptomic and epigenetic responses to influenza infection in pigs from high or low birth...

Type 2 porcine reproductive and respiratory syndrome virus infection increases apoptosis at the maternal-fetal interface in late gestation pregnant gilts
Download2017-03-01
Novakovic, Predrag, Harding, John C. S., Al-Dissi, Ahmad N., Detmer, Susan E.
The pathogenesis of fetal death associated with porcine reproductive and respiratory syndrome (PRRS) is hypothesized to be a consequence of PRRS virus-induced apoptosis at the maternal-fetal interface (MFI). The objectives of this study were to evaluate distribution and degree of apoptosis in the...
