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...

Maternal and fetal thyroid dysfunction following porcine reproductive and respiratory syndrome virus2 infection
Download2020-01-01
Pasternak, J. Alex, MacPhee, Daniel J., Harding, John C. S.
To better understand the host response to porcine reproductive and respiratory virus-2 (PRRSV2) we evaluated circulating thyroid hormone and associated gene expression in a late gestation challenge model. Pregnant gilts were inoculated at gestation day 85 and fetal samples collected at either 12...

Novel Resilience Phenotypes Using Feed Intake Data From a Natural Disease Challenge Model in Wean-to-Finish Pigs
Download2019-01-01
Putz, Austin M., Harding, John C. S., Dyck, Michael K., Fortin, F., Plastow, Graham S., Dekkers, Jack C. M., PigGen Canada
The objective of this study was to extract novel phenotypes related to disease resilience using daily feed intake data from growing pigs under a multifactorial natural disease challenge that was designed to mimic a commercial environment with high disease pressure to maximize expression of...

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...

Putting the microbiota to work: Epigenetic effects of early life antibiotic treatment are associated with immune-related pathways and reduced epithelial necrosis following Salmonella Typhimurium challenge in vitro
Download2020-04-01
Costa, Matheus O., Fouhse, Janelle, Silva, Ana Paula P., Wiling, Benjamin, Harding, John C. S.
Salmonella enterica serovar Typhimurium is an animal welfare and public health concern due to its ability to parasite livestock and potentially contaminate pork products. To reduce Salmonella shedding and the risk of pork contamination, antibiotic therapy is used and can contribute to...

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...

Costa, Matheus O., Nosach, Roman, Harding, John C. S.
Background:Most interactions between pathogenic microorganisms and their target host occur on mucosal surfaces of internal organs such as the intestine. In vitro organ culture (IVOC) provides an unique tool for studyinghost-pathogen interactions in a controlled environment. However, this...

Chen, Yulu, Tibbs Cortes, Laura E., Ashley, Carolyn, Putz, Austin M., Lim, Kyu-Sang, Dyck, Michael K., Fortin, Frederic, Plastow, Graham S., Dekkers, Jack C. M., Harding, John C. S., PigGen Canada
Background Disease resilience is the ability to maintain performance under pathogen exposure but is difficult to select for because breeding populations are raised under high health. Selection for resilience requires a trait that is heritable, easy to measure on healthy animals, and genetically...

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...
