Differential responses in placenta and fetal thymus at 12 days post infection elucidate mechanisms of viral level and fetal compromise following PRRSV2 infection
Download2020-01-01
Van Goor, Angelica, Pasternak, Alex, Walker, Kristen, Hong, Linjun, Malgarin, Carolina, MacPhee, Daniel J., Harding, John C. S., Lunney, Joan K.
Background:A pregnant gilt infected with porcine reproductive and respiratory syndrome virus (PRRSV) can transmit the virus to her fetuses across the maternal-fetal-interface resulting in varying disease outcomes. However,the mechanisms leading to variation in fetal outcome in response to PRRSV...

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...

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...

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...

Comparison of host genetic factors influencing pig response to infection with two North American isolates of porcine reproductive and respiratory syndrome virus
Download2016-01-01
Hess, Andrew S., Islam, Zeenath, Hess, Melanie K., Rowland, Raymond R. R., Lunney, Joan K., Doeschl-Wilson, Andrea, Plastow, Graham S., Dekkers, Jack C. M.
Background:Porcine reproductive and respiratory syndrome (PRRS) is one of the most important swine diseases in the world and genetic selection of pigs for increased resistance to PRRS is an attractive method to improve the health status of the swine herd. This study compared phenotypic and...

Wilkinson, Jamie M., Ladinig, Andrea, Bao, Hua, Kommadath, Arun, Stothard, Paul, Lunney, Joan K., Harding, John C. S., Plastow, Graham S.
Porcine Reproductive and Respiratory Syndrome Virus (PRRSV) infection of pregnantfemales causes fetal death and increased piglet mortality, but there is substantial variationin the extent of reproductive pathology between individual dams. This study used RNA-sequencing to characterize the whole...

Ladinig, Andrea, Stothard, Paul, Wilkinson, Jamie M., Kommadath, Arun, Plastow, Graham S., Harding, John C. S., Bao, Hua, Lunney, Joan K.
Porcine Reproductive and Respiratory Syndrome Virus (PRRSV) infection of pregnant females causes fetal death and increased piglet mortality, but there is substantial variation in the extent of reproductive pathology between individual dams. This study used RNA-sequencing to characterize the whole...

Bai, Xuechun, Putz, Austin M., Wang, Zhiquan, Fortin, Frederic, Harding, John C. S., Dyck, Michael K., Dekkers, Jack C. M., Field, Catherine J., Plastow, Graham S., PigGen Canada
Disease resilience is a valuable trait to help manage infectious diseases in livestock. It is anticipated that improved disease resilience will sustainably increase production efficiency, as resilient animals maintain their performance in the face of infection. The objective of this study was to...

Fetal Metabolomic Alterations Following Porcine Reproductive and Respiratory Syndrome Virus Infection
Download2020-12-11
Malgarin, Carolina M., MacPhee, Daniel J., Harding, John C. S.
PRRSV infection in third-trimester pregnant sows can lead to fetal death and abortions, although the mechanisms triggering these effects are not well understood. Since resistant and susceptible fetuses can coexist in the same litter, we propose that there may be differential mechanisms used by...

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...
