Understanding Strangles in Horses: Recent Outbreak and Prevention
The recent report of three horses testing positive for strangles in Maryland reminds us of the lurking challenge this disease poses in the equine world. **Strangles**, a highly contagious bacterial disease, can lead to severe health issues among horses if not managed properly. Let's delve into what strangles is, how it spreads, and more importantly, how we can prevent it.
Spotlight on the Maryland Cases
Recently, one horse in Calvert County and two in St. Mary’s County were diagnosed with strangles. They are currently quarantined, a critical step to prevent further spread of the disease. The pathogen behind this condition, Streptococcus equi subspecies equi, tends to hop from one horse to another through **direct contact** or contact with contaminated objects like feed buckets and handlers' hands.
The Clinical Picture: Symptomes of Strangles
Strangles often manifests with some very tell-tale signs. Affected horses typically display:
- Fever
- Swollen or abscessed lymph nodes forming painful lumps under the jaw or in the throat
- Nasal discharge
- Coughing or wheezing
- Difficulty swallowing due to inflamed lymph nodes
Recognizing these symptoms early plays a vital role in managing and preventing the disease's spread.
Diagnosis and Treatment: Treading Cautiously
Strangles is diagnosed through **PCR testing** from nasal swabs or abscess samples to confirm the bacteria's presence. The severity of the symptoms dictates the treatment approach, with many cases being managed without antibiotics to avoid dampening the horse's natural immunity. **Antibiotics**, while necessary for severe cases, can interfere with immune response if overused, potentially lengthening the infectious period.
Biosecurity: The First Line of Defense
An effective vaccine is available, though it varies in its efficacy, making biosecurity the most reliable defense. Some key practices include:
- Quarantining new arrivals to prevent potential disease spread.
- Disinfecting surfaces and equipment regularly to lower contamination risks.
- Implementing hygiene practices such as handwashing for anyone handling horses.
- Keeping a close watch for early signs of illness to ensure swift isolation of affected horses.
The recent Maryland cases highlight why rigorous biosecurity protocols are indispensable. They serve as a robust measure against the potential spread of strangles, protecting both the horses and the broader equine industry.
The Role of Equine Disease Communication Center (EDCC)
The Equine Disease Communication Center is a significant linchpin in managing equine disease outbreaks. By collecting and disseminating verified information, the EDCC equips equine communities with the knowledge needed to tackle outbreaks promptly and effectively.

In conclusion, while strangles remains a quintessential risk in the equine community, understanding its dynamics and embracing solid preventative strategies are fundamental steps in safeguarding horse health. A little humor might remind us that if horses could speak, they'd likely say, "An ounce of prevention is worth a pound of feed!"
