First Report on Ovariohysterectomy for the Treatment of Pyometra in a Golden Retriever Dog in Mongolia

Abstract

A 4-year-old female Golden Retriever dog was brought to the Animal Health Centre with complaints of anorexia, purulent and blood-tinged discharge, and white foamy vomit. The dog was clinically diagnosed with pyometra and was successfully treated with ovariohysterectomy. Bacteriological testing revealed a bacterial infection with Proteus vulgaris that was resistant to antibiotics including vancomycin, novobiocin, and penicillin. Histopathological examination showed multifocal cystic hyperplasia of the endometrial glands, severe abscessation of the glandular lumen, and severe infiltration of lymphocytes and plasma cells in the muscle layer. The dog recovered and showed normal hematology and biochemical parameters after ovariohysterectomy, antibiotics administrations, and supportive care. This case report including the diagnosis and surgical management of pyometra will be a very important resource for the development of small animal clinical skills and clinical training in Mongolia.
