Exploring Phenotypes for Disease Resilience in Pigs Using Complete Blood Count Data From a Natural Disease Challenge Model
Download2020-01-01
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...

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...

Genomic Analysis of IgG Antibody Response to Common Pathogens in Commercial Sows in Health-Challenged Herds
Download2020-10-23
Sanglard, Leticia P., PigGen Canada, Mote, Benny E., Willson, Philip, Harding, John C. S., Plastow, Graham S., Dekkers, Jack C. M., Serao, Nick V. L.
Losses due to infectious diseases are one of the main factors affecting productivity in the swine industry, motivating the investigation of disease resilience-related traits for genetic selection. However, these traits are not expected to be expressed in the nucleus herds, where selection is...

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...

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...

The genetic basis of natural antibody titersof young healthy pigs and relationshipswith disease resilience
Download2020-01-01
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...

Amat, Samat, Lantz, Hannah, Munyaka, Peris M., Willing, Benjamin P.
A diverse and dynamic microbial community (known as microbiota) resides within the pig gastrointestinal tract (GIT). The microbiota contributes to host health and performance by mediating nutrient metabolism, stimulating the immune system, and providing colonization resistance against pathogens....

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...

Kinome profiling of peripheral blood mononuclear cells collected prior to vaccination reveals biomarkers and potential mechanisms of vaccine unresponsiveness in pigs
Download2020-12-01
Lipsit, Sean W. L., Wilkinson, James, Scruten, Erin, Facciuolo, Antonio, Denomy, Connor, Griebel, Philip J., Kusalik, Anthony, Plastow, Graham, Napper, Scott
Inter-individual variance in host immune responses following vaccination can result in failure to develop protective immunity leaving individuals at risk for infection in addition to compromising herd immunity. While developing more efficacious vaccines is one strategy to mitigate this problem,...

Discovery of Predictors of Mycoplasma hyopneumoniae Vaccine Response Efficiency in Pigs: 16S rRNA Gene Fecal Microbiota Analysis
Download2020-07-22
Munyaka, Peris M., Blanc, Fany, Estelle, Jordi, Lemonnier, Gaetan, Leplat, Jean-Jacques, Rossignol, Marie-Noelle, Jardet, Deborah, Plastow, Graham, Billon, Yvon, Willing, Benjamin P., Rogel-Gaillard, Claire
The gut microbiota comprises a large and diverse community of bacteria that play a significant role in swine health. Indeed, there is a tight association between the enteric immune system and the overall composition and richness of the microbiota, which is key in the induction, training and...
