Here, we use a rat model of congenital RVF to identify tropisms, pathologies, and immune responses in the placenta during vertical transmission. Infection of late-gestation pregnant rats resulted in vertical transmission to the placenta and widespread infection throughout the decidua, basal zone, and labyrinth zone. Some pups from infected dams appeared normal while others had gross signs of teratogenicity including death. Histopathological lesions were detected in placenta from pups regardless of teratogenicity, while teratogenic pups had widespread hemorrhage throughout multiple placenta layers. Teratogenic events were associated with significant increases in placental pro-inflammatory cytokines, type I interferons, and chemokines. RVFV displays a high degree of tropism for all placental tissue layers and the degree of hemorrhage and inflammatory mediator production is highest in placenta from pups with adverse outcomes. Given the potential for RVFV to emerge in new locations and the recent evidence of emerging viruses, like Zika and SARS-CoV-2, to undergo vertical transmission, this study provides essential understanding regarding the mechanisms by which RVFV crosses the placenta barrier.<\/jats:p>","DOI":"10.1371\/journal.pntd.0010898","type":"journal-article","created":{"date-parts":[[2022,10,31]],"date-time":"2022-10-31T13:53:09Z","timestamp":1667224389000},"page":"e0010898","update-policy":"https:\/\/doi.org\/10.1371\/journal.pntd.corrections_policy","source":"Crossref","is-referenced-by-count":13,"title":["Congenital Rift Valley fever in Sprague Dawley rats is associated with diffuse infection and pathology of the placenta"],"prefix":"10.1371","volume":"16","author":[{"given":"Cynthia M.","family":"McMillen","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Devin A.","family":"Boyles","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stefan G.","family":"Kostadinov","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ryan M.","family":"Hoehl","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Madeline M.","family":"Schwarz","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joseph R.","family":"Albe","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matthew J.","family":"Demers","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0857-2973","authenticated-orcid":true,"given":"Amy L.","family":"Hartman","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"340","published-online":{"date-parts":[[2022,10,31]]},"reference":[{"issue":"3","key":"pntd.0010898.ref001","first-page":"1137","article-title":"Factors associated with rift valley fever in south-west Saudi Arabia","volume":"25","author":"AA Elfadil","year":"2006","journal-title":"Rev Sci Tech"},{"issue":"5","key":"pntd.0010898.ref002","first-page":"941","article-title":"Rainfall and epizootic Rift Valley fever","volume":"63","author":"FG Davies","year":"1985","journal-title":"Bulletin of the World Health Organization"},{"issue":"9","key":"pntd.0010898.ref003","doi-asserted-by":"crossref","DOI":"10.1128\/JVI.01394-19","article-title":"Rift Valley Fever: a Threat to Pregnant Women Hiding in Plain Sight?","volume":"95","author":"CM McMillen","year":"2021","journal-title":"Journal of virology"},{"key":"pntd.0010898.ref004","first-page":"77","volume-title":"Contributions to Epidemiology and Biostatistics","author":"BJ Erasmus","year":"1981"},{"issue":"4","key":"pntd.0010898.ref005","first-page":"205","article-title":"The pathology of Rift Valley fever.
