We document a case series of abortions and placentitis in domestic pigs from the Midwest United States where aerobic bacterial cultures consistently isolated Trueperella abortisuis. Cases were submitted between 2017-2020 to the Kansas State Veterinary Diagnostic Lab. Microscopically, there was suppurative placentitis with necrosis and intralesional, gram-positive coccobacilli. In all cases, molecular diagnostics were negative for major causes of abortion in pigs. This is the first known report of T abortisuis isolated from swine abortions or placentitis in the United States.
