Plain-English summary
A 4-year-old Thoroughbred mare was brought in due to issues with her placenta, including abnormalities and a retained piece after giving birth. Tests showed a specific type of bacteria (Amycolatopsis spp.) in her placenta. The vet treated her with a flushing procedure and oxytocin, which helped her expel the retained placenta shortly after delivery. Unfortunately, while the foal was initially healthy, it later died from complications during surgery at 7 weeks old, and the mare did not conceive again despite several attempts.

Abstract
CASE DESCRIPTION: A 4-year-old Thoroughbred mare was evaluated because of placental abnormalities and a retained placental remnant. CLINICAL FINDINGS: Microbial culture of the placenta yielded pure growth of Amycolatopsis spp. Histologic examination of the placenta revealed a focally expanding chorionitis with intralesional gram-positive filamentous bacilli and multifocal allantoic adenomatous hyperplasia on the apposing allantoic surface. TREATMENT AND OUTCOME: Treatment with lavage and oxytocin resulted in expulsion of the placental remnant within hours of parturition. The mare did not become pregnant again despite multiple breedings. The foal appeared healthy but died of complications during an elective surgical procedure at 7 weeks of age. CONCLUSIONS AND CLINICAL RELEVANCE: To the author's knowledge, all previously confirmed cases of nocardioform placentitis have been in mares bred in the central Kentucky region. Indications that the pathogen in the mare reported here is a different species than that isolated in Kentucky suggest that this is an emerging disease. Mares with nocardioform placentitis usually do not have the same clinical signs as mares with placentitis resulting from an ascending pathogen.
