Effect of intrauterine infusion on embryo recovery, interferon tau concentration, serum progesterone, and anti-Müllerian hormone. Cows were synchronized and inseminated on day 130 post-infusion of either LB broth vehicle medium (vehicle; n = 11) or pathogenic E. coli and T. pyogenes in LB broth (bacteria; n = 12). Uterine content was collected ex vivo, 16 days post-insemination. All recovered embryos were filamentous in morphology (A). Interferon tau (IFNT) concentration (B) was quantified in uterine fluid by ELISA. Serum progesterone (C) was quantified 15 days after insemination. Each dot represents a cow and the solid line is the mean. Anti-Müllerian hormone (D) was quantified on day −2 prior to intrauterine infusion and day 145 after infusion. Each dot represents a cow.
