“…11 In dairy cows, pyometra is often the result of ovulation occurring before uterine involution is complete that results in the formation of a corpus luteum and closure of the cervix before the uterus is cleared of all pathogens. 12 In both dairy and beef cows, pyometra can also result from pathogen introduction during insemination or breeding, as can be the case with Tritrichomonas foetus infections. 12 In canines, pyometra occurs frequently in conjunction with cystic endometrial hyperplasia due to the effects of progesterone on the uterine lining during the diestrus stage of the female cycle.…”

“…Systemically affected cows with metritis are usually termed as having septic and/or toxic metritis, which has different treatments and implications than a metritis localized to the uterus. 12 In female dogs, metritis is a disease of the puerperal period and occurs 0-7 days after whelping frequently resulting in systemic illness. 18 In mares, metritis also extends through the uterine wall, making equids more prone to developing perimetritis and peritonitis which can lead to laminitis and septicemia.…”

“…Classifications of clinical and subclinical endometritis in cows have recently been proposed, depending on the presence of discharge or lack thereof, respectively, and is limited to diagnosis in animals > 21 days after calving, as cows have an extended uterine involution period. 12 In female dogs, endometritis may present as part of a cystic endometrial hyperplasia-pyometra complex 14 or on its own as a source of infertility. 22 In sows, endometritis is associated with infertility that can be either temporary or permanent.…”

A second parity, late pregnant, commercial mixed-breed sow was examined on a farm with a 5-day history of inappetence and lethargy that was unresponsive to treatment with flunixin meglumine. Clinical signs were suspected due to an enlarged, fluid-filled hollow abdominal organ identified via transabdominal ultrasonography. Further characterization of abdominal viscera and fluid was limited by the sensitivity of the imaging equipment. Flunixin meglumine was discontinued and a dietary supplement was added to the feed to encourage intake. Repeat transabdominal ultrasonography was performed 4 days later due to a lack of improvement with worsening lethargy, continued inappetence, and fever. The sow was euthanized because of poor prognosis, chronicity of disease, and lack of pregnancy. On necropsy, the uterine horns measured 20 cm in diameter and occupied ~ 80% of the abdominal cavity, compressing the intestines and liver. The uterine lumen contained watery, turbid fluid. The left ovary had multiple grossly appreciable corpora lutea, and right ovary had multiple corpora albicantia. Although uterine disease is poorly defined in swine, based on the gross and histologic findings this sow was diagnosed with nonpuerperal chronic endometritis with intrauterine accumulation of purulent fluid (consistent with pyometra). Additionally, the sow was diagnosed with salpingitis, interstitial nephritis, lymphadenitis, and gastric ulceration, all likely contributing to her declining health and systemic illness.
