Strangles in Equines: A Growing Concern
Strangles, a respiratory ailment caused by the bacterium Streptococcus equi subspecies equi, is a highly contagious disease among horses. Recently, this disease was confirmed in a 24-year-old Tennessee Walking Horse gelding in Livingston County, Michigan. This case serves as a stark reminder of its rapid transmission and the paramount importance of biosecurity on horse properties.The Michigan Case: A Wake-up Call
On December 22, the affected horse began to show clinical symptoms, including fever, nasal discharge, and coughing. A subsequent PCR test on January 5 confirmed the presence of strangles. Now, the gelding is on the road to recovery, but two other horses on the property are suspected of infection while three more have been exposed. Each movement of the horses during this time underscores the need for stringent hygiene practices in stables.Spreading Like Wildfire: Understanding Strangles Transmission
Strangles is known to be social—or, rather, it spreads easily through both direct and indirect contact. The bacterium thrives in environments where horses share buckets, feeders, and other equipment. Even horses not displaying obvious symptoms can be carriers, shedding bacteria long after showing clinical signs. In the absence of effective management, barns with high horse traffic are vulnerable to outbreaks, resulting in unpleasant surprises for horse owners.Symptoms of Equine Strangles
Clinically, strangles presents with a range of symptoms. Most horses experience fever, nasal discharge, and swollen lymph nodes. Others may endure severe symptoms like muscle swelling, coughing, and difficulty swallowing. Occasionally, the infection can spread deeper into the horse's body, turning a standard case of strangles into a severe threat.Diagnosing and Treating Strangles
Typically, veterinarians use PCR testing to accurately diagnose strangles. Testing samples can include nasal swabs, nasopharyngeal washes, or abscess tissues. For treating this pesky illness, supportive care aims to manage symptoms like fever, while abscess management is priority. Despite this, antibiotics are a last resort, reserved for severe cases where respiration is compromised, as antibiotics can interfere with the development of immunity in horses.Prevention: The Best Medicine
Preventative measures can indeed make a significant difference in curbing the impact of strangles. Though a vaccine exists, its efficacy varies, making it a part, not the totality, of a disease prevention strategy. The real power lies in robust biosecurity practices. Quarantining new arrivals, isolating ill horses, and maintaining high cleanliness standards are vital. Strategic management of horse traffic on and off the property can suppress potential outbreaks before they even start.The Role of the Equine Disease Communication Center (EDCC)
The EDCC plays a crucial role in monitoring and communicating about equine diseases. Operating as an independent nonprofit, the EDCC provides accurate and timely information about disease outbreaks. Thanks to programs like the EDCC Health Watch, crucial information is disseminated, assisting in the rapid response to emerging disease threats. In conclusion, as equine diseases continue to threaten horse populations, understanding and preventing diseases like strangles is of utmost importance. Effective communication, prevention strategies, and ongoing research are all indispensable tools for horse owners and operators, striving to provide healthier and safer environments for their horses.Source: Practical Horseman Magazine
