Strangles in Horses Michigan has once again made headlines as a second horse at an Oakland County facility tested positive for the infectious disease. This article covers the recent cases, signs of strangles, diagnostic procedures, treatment options, and preventive measures every horse owner should know.
Recent Cases in Oakland County
On October 27, 2025, a 22-year-old draft gelding in Oakland County, Michigan, tested positive for strangles in horses Michigan, following a previous case at the same facility on October 10. The horse is currently recovering under veterinary care, highlighting the importance of monitoring and timely reporting in preventing outbreaks.
Understanding Strangles in Horses
Strangles in horses is caused by the bacterium Streptococcus equi subspecies equi. The infection spreads through direct contact between horses or via contaminated surfaces. Even horses that appear healthy can carry and transmit the bacteria, making early detection crucial. Recovered horses can remain contagious for at least six weeks, posing a long-term risk for outbreaks.
Symptoms of Strangles
Infected horses may display a range of symptoms, including:
- Fever
- Swollen or abscessed lymph nodes
- Nasal discharge
- Coughing or wheezing
- Muscle swelling
- Difficulty swallowing
Diagnosis and Treatment
Veterinarians typically confirm strangles in horses Michigan using polymerase chain reaction (PCR) tests, which may involve nasal swabs, washes, or abscess samples. Treatment is generally based on clinical signs, with antibiotics reserved for severe cases. Overuse of antibiotics can hinder immunity development, so careful veterinary guidance is essential. Most horses recover fully within three to four weeks.
Prevention and Biosecurity Measures
While vaccines are available, they are not always fully effective. Horse owners can reduce the risk of outbreaks through strict biosecurity measures, such as:
- Quarantining new horses before introducing them to the facility
- Maintaining high standards of hygiene
- Regularly disinfecting surfaces and equipment
