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...

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

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...

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...

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...

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...
