Placentitis has been reported as the most important cause of equine abortions, stillbirths, and perinatal deaths in horses. Most cases are caused by bacteria and less commonly by fungal elements. The aim of this report is to describe the clinical presentation of a fungal placentitis caused by Aspergillus terrerus. A 5-year-old thoroughbred maiden mare at the 217th day of gestation presented with some classic signs of placentitis (premature udder development and milk dripping). All ultrasonographic findings were consistent with a live fetus and a severe placentitis. On vaginal examination, purulent discharge was found coming from the external cervical os. Samples sent for culture yielded very small numbers of mixed growth including Enterococcus faecalis (by matrix-assisted laser desorption/ionization time-of-flight mass spectrometer), Streptococcus viridans, and Aspergillus terreus, and polymerase chain reaction was positive for Aspergillus terreus and Pseudomonas. The mare was placed on broad-spectrum antimicrobials, nonsteroidal anti-inflammatories, and hormonal and antifungal treatment. The fetus kept on developing and growing despite the placentitis for 14 days until the demise of the fetus in utero occurred. Aspergillus terreus was isolated from the chorionic surface but not from the fetus. Fungal placentitis is not very commonly found in mares. The extent of the placental lesions and the severity of the placentitis contributed to the death of the fetus. This is one of the few case reports available describing fungal placentitis. Aspergillus terreus has not been previously reported as a cause of placentitis.
