Strangles: How to Protect Your Horse
 
Horses are traveling more than ever before, and whether they’re heading down the road or across the country, factors associated with transportation can leave your horse at risk for disease threats. One of the most common equine diseases—as well as one of the most contagious—is strangles.
 
Strangles, caused by the bacteria Streptococcus equi, is a highly contagious upper respiratory disease most common in young horses. It also has several potentially fatal complications and the capability to cause persistent infections in populations of asymptomatic carrier horses.
 
Clinical signs of strangles can include fever, nasal discharge, difficulty swallowing, abnormal breathing, and swelling and/or abscesses of the lymph nodes.
 
“Commonly, a horse with strangles will have profuse nasal discharge and swollen submandibular lymph nodes,” said Kevin Hankins, DVM, MBA, senior equine technical services veterinarian for Zoetis. “With strangles, about 10% of horses don’t fully recover from the disease and can then become persistent carriers. Unfortunately, persistent carrier horses don’t show the outward clinical signs that sick horses do.”
 
Due to the lack of outward signs in carrier horses, strangles can spread quickly and easily through a barn or herd because of its ability to be transmitted through direct animal-to-animal contact or by objects such as bridles, buckets, or human hands.
