However, pregnancy is less likely to occur if cows had a postpartum bacterial infection of the uterus, even after the resolution of disease. We hypothesized that uterine bacterial infection alters the endometrial transcriptomic signature of pregnancy after the resolution of disease. To examine the endometrial transcriptomic signature of pregnancy, cows were inseminated 130 days after intrauterine infusion of pathogenic <jats:italic>Escherichia coli<\/jats:italic> and <jats:italic>Trueperella pyogenes<\/jats:italic>, subsequently endometrium was collected 16 days after insemination for RNA sequencing. We found 171 pregnancy regulated genes in cows 146 days after bacterial infection. When comparing our findings with previous studies that described the endometrial transcriptomic signature of pregnancy in healthy cows, 24 genes were consistently differentially expressed in pregnancy, including <jats:italic>MX1<\/jats:italic>, <jats:italic>MX2<\/jats:italic> and <jats:italic>STAT1<\/jats:italic>. However, 12 pregnancy regulated genes were found only in the endometrium of healthy cows, including <jats:italic>ISG15<\/jats:italic> and <jats:italic>TRANK1<\/jats:italic>. Furthermore, 28 pregnancy regulated genes were found only in the endometrium of cows following bacterial infection and these were associated with altered iNOS, TLR, and IL-7 signaling pathways. Although 94 predicted upstream regulators were conserved amongst the studies, 14 were found only in the endometrium of pregnant healthy cows, and 5 were found only in cows following bacterial infection, including AIRE, NFKBIA, and DUSP1. In conclusion, there were both consistent and discordant features of the endometrial transcriptomic signature of pregnancy 146 days after intrauterine bacterial infusion. These findings imply that there is an essential transcriptomic signature of pregnancy, but that infection induces long-term changes in the endometrium that affect the transcriptomic response to pregnancy.<\/jats:p>","DOI":"10.1371\/journal.pone.0265062","type":"journal-article","created":{"date-parts":[[2022,3,31]],"date-time":"2022-03-31T17:55:01Z","timestamp":1648749301000},"page":"e0265062","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":19,"title":["The endometrial transcriptomic response to pregnancy is altered in cows after uterine infection"],"prefix":"10.1371","volume":"17","author":[{"given":"Mackenzie J.","family":"Dickson","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jeanette V.","family":"Bishop","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas R.","family":"Hansen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"I.
