Strangles is a highly contagious bacterial infection that affects horses, caused by the bacterium Streptococcus equi. This illness can lead to serious health complications if not properly managed, making it vital for horse owners and caregivers to understand its causes, symptoms, and treatment options.

What is Strangles?

Strangles primarily affects young horses, although any horse can contract the infection. It is characterized by swelling of the lymph nodes and abscess formation, leading to symptoms such as fever, difficulty swallowing, and nasal discharge. The disease is transmitted through direct contact with infected horses or contaminated equipment, making biosecurity measures essential in preventing outbreaks.

Symptoms of Strangles

Common symptoms of strangles include:

• Fever (often above 101.5°F or 38.6°C)
• Swollen lymph nodes, especially around the jaw and throat
• Nasal discharge, which may be yellowish or green
• Coughing and difficulty breathing
• Loss of appetite and lethargy

Diagnosis and Treatment

If a horse is suspected of having strangles, a veterinarian will perform an examination and may take nasal swabs to confirm the presence of Streptococcus equi. Treatment typically includes:

• Antibiotics to manage the infection
• Supportive care such as hydration and anti-inflammatory medications
• In some cases, surgical drainage of abscesses may be necessary

Preventing Strangles

Preventing strangles is essential for maintaining a healthy environment for horses. Here are some key preventive measures:

• Isolate new horses for at least 2-3 weeks before introducing them to existing horses.
• Maintain good hygiene practices, including regular cleaning and disinfection of stalls and equipment.
• Vaccination may also be considered under the guidance of a veterinarian, especially in areas where strangles is prevalent.

Conclusion

Strangles is a serious bacterial infection that can significantly impact horse health. Understanding its symptoms, diagnosis, treatment, and prevention strategies is crucial for horse owners. By staying informed and proactive, you can help protect your horse and reduce the risk of spreading this contagious disease.
