Strangles in Horses: Understanding the Latest Outbreak
A recent case of strangles has been confirmed at a stable in St. Johns County, Florida. This incident serves as a critical reminder of the importance of stringent biosecurity measures and well-informed veterinary practices to manage this highly contagious equine disease.
What is Strangles?
Strangles is caused by the bacterium Streptococcus equi subspecies equi, which targets horses' upper respiratory tracts and lymph nodes. The disease is notorious for spreading quickly via direct or indirect contact, making barns and stables particularly susceptible to outbreaks. Interestingly, some horses can appear clinically normal yet continue to shed the bacteria for weeks, acting as silent carriers.
Recognizing the Symptoms
Horses afflicted with strangles often display several hallmark symptoms:
- Fever and depression
- Reduced appetite and thick nasal discharge
- Painful, swollen lymph nodes around the head and neck
- In severe cases, difficulty swallowing or breathing
It's crucial to keep a close eye on these symptoms to manage and contain an outbreak effectively.
Diagnosis and Treatment
To confirm strangles, veterinarians typically rely on polymerase chain reaction (PCR) testing, a highly sensitive technique that can identify the organism even in asymptomatic carriers. Diagnosis can also involve collecting cultures from nasal swabs or abscess contents.
Treating strangles focuses on supportive care, as the use of antibiotics is somewhat controversial. For most straightforward cases, rest, hydration, and anti-inflammatory medications are recommended. Antibiotics are only advised for severe instances where the horse experiences respiratory distress or other complications.
Preventive Measures and Vaccination
In dealing with strangles, prevention is undoubtedly better than cure. Vaccinations are available and can be administered as either intranasal or intramuscular products. While vaccination doesn't completely prevent infection, it can reduce disease severity and limit its spread. However, it's essential to follow the correct vaccination protocols to ensure efficacy and avoid complications.
Lessons from the Florida Case
The recent Florida outbreak underscores several critical points for managing strangles:
- Promptly impose movement restrictions and isolate affected horses.
- Adopt strict biosecurity measures, such as dedicated equipment and proper hand hygiene.
- Monitor temperatures of exposed horses daily to identify new cases swiftly.
- Engage with a veterinarian to tailor treatment, vaccination, and carrier screening.
The role of organizations like the Equine Disease Communication Center (EDCC) is invaluable. Their efforts in collecting and distributing data on outbreaks provide a framework for quick and effective responses.

Conclusion
Strangles remains a significant challenge in equine health, but with coordinated efforts involving diagnostics, appropriate therapy, and facilitations like those from the EDCC, outbreaks can be managed and controlled. Especially for those in the equine community, awareness and responsiveness are paramount in protecting our cherished equine companions.
