Pyometra is a chronic uterine infection, typically caused by a cervix that does not open normally. It overlaps with the diagnosis of endometritis.
In a pyometra, infection takes hold and continues because the uterus cannot empty or clear the infectious agents. The uterus fills with pus and becomes akin to a huge abscess. In cases of a severe pyometra, the uterus may contain 5 gallons of pus or more.
This closed infection makes the mare feel terrible, causing lack of appetite, fever, and colic signs due to stretch on the uterine wall. Treatment involves a combination of opening of the cervix, drainage of pus, uterine flushing with antibiotic treatment. Ultimately, surgical removal of the uterus (hysterectomy), may be required. In most cases, mares that have a pyometra become permanently infertile.
