Understanding Strangles in Horses
Strangles in horses is an infection caused by Streptococcus equi subspecies equi that is spread through direct contact with other equids or contaminated surfaces. Notably, horses that aren’t showing clinical signs can still harbor the bacteria and potentially spread the disease. In fact, recovered horses remain contagious for at least six weeks, thereby upping the potential to cause outbreaks in the long term.
Beware of Strangles Symptoms
As a horse owner, you must be extra vigilant about your horse's health. Watch out for the following clinical signs of infection in horses:
- Fever
- Swollen and/or abscessed lymph nodes
- Nasal discharge
- Coughing or wheezing
- Muscle swelling
- Difficulty swallowing
Veterinary Diagnosis
When a horse displays these symptoms, qualified veterinarians use polymerase chain reaction (PCR) testing with either a nasal swab, wash, or an abscess sample to make a diagnosis. Treatment is usually based on the severity of clinical signs, with antibiotics for severe cases. However, overuse of antibiotics can prevent an infected horse from developing immunity. Despite the trials of the infection, most horses make a full recovery in three to four weeks.
Prevention is Better Than Cure
While a vaccine is available, its effectiveness cannot always be guaranteed. Hence, other biosecurity measures may be more reliable. For example, quarantining new horses at a facility and maintaining high standards of hygiene and disinfecting can substantially lower the risk of an outbreak, or contain one if it occurs. Remember, outbreak prevention is always better than chasing cures.
Case Report: Strangles in Ottawa County, Michigan
Three horses in Ottawa County, Michigan, were confirmed positive for strangles on March 13 after developing clinical signs in February. The affected horses include a 9-year-old Quarter Horse gelding, 2-year-old Quarter Horse filly, and 8-year-old Quarter Horse gelding. As a result, they are under quarantine, and 31 horses are potentially exposed. It's crucial to keep the equine community informed about such instances to prevent further spread of the disease.
In conclusion, horse owners, trainers, veterinarians, and equine enthusiasts must remain vigilant about the health and welfare of their horses. Through early detection of symptoms, appropriate veterinary care, and rigorous biosecurity measures, the risk of strangles and other diseases can be significantly reduced. Remember, healthy horses mean happy owners!Source: TheHorse.com
