The impact of late gestation PRRSV-2 infection is highly variable within a litter, with a subset of fetuses displaying varying degrees of compromise following infection while others remain viable despite significant systemic viral load. To understand

Abstract Porcine reproductive and respiratory syndrome virus (PRRSV) in late gestation causes a profound suppression of circulating maternal and fetal thyroid hormone during a critical window of development. To understand this relationship, we evalua

Abstract Porcine reproductive and respiratory syndrome virus (PRRSV) infection during late gestation negatively affects fetal development. The objective of this study was to identify the fetal organs most severely impacted following infection, and ev

Abstract Background Mechanisms of fetal death following maternal PRRSV2 infection remain uncharacterized, although hypoxia from umbilical cord lesions and/or placental detachment due to apoptosis are hypothesized. We performed two experiments examini

Abstract 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 ge

To protect the health of sows and gilts, significant investments are directed toward the development of vaccines against infectious agents that impact reproduction. We developed an intrauterine vaccine that can be delivered with semen during artifici

Understanding why intrauterine growth restricted (IUGR) fetuses are more resilient to transplacental porcine reproductive and respiratory syndrome virus-2 (PRRSV-2) infection compared to normal fetuses may lead to alternative approaches to control PR

Background Silicosis develops after inhalation of dust containing respirable crystalline silica (RCS) and is recognized as an occupational disease. Workers also develop accelerated and acute silicosis after shorter exposure to respirable silica dust
