About equine strangles
Equine strangles is a severe, common, and highly contagious horse disease where the horse develops fever, nasal discharge, cough, and sometimes large abscesses in the lymph nodes of the head and neck. Equine strangles is caused by the streptococcus bacteria Streptococcus equi. The onset of the disease can range from mild cold-like symptoms to severe abscesses in the throat that can burst, leading to breathing difficulties. The mortality rate is up to 10 percent in infected herds, but more typically around 2 percent. Equine strangles can also cause secondary infections such as pneumonia or abscesses in other parts of the body. It affects horses worldwide, except for Iceland where the import of horses is prohibited. Some of the horses that recover from strangles remain persistently infected. These silent carriers are perceived by others as completely healthy animals, but they spread the bacteria to the environment and to other horses with which they come into contact. Outbreaks of equine strangles often have significant consequences for horse owners, as isolation, closure, and other measures are required. The Swedish National Veterinary Institute (SVA) recommends isolating all horses on the premises, both sick and asymptomatic, for four to six weeks from the day of the last symptoms observed in the last affected horse.
