STRANGLES: NEW MILLENNIUM, SAME DISEASE
Strangles was one of the first equine diseases to be described by the early writers of veterinary science. Unfortunately, not a great deal about the disease has changed over the centuries.
Strangles is still widely reported in North America and all other areas with major populations of horses. One of the main factors contributing to the spread of the disease is the movement of horses, particularly those that no longer show clinical signs but still shed the organism in their nasal secretions.
The organism that causes strangles is a bacterium called Streptococcus equi. Transfer from horse to horse usually involves direct face-to-face contact, or exposure of horses to such things as contaminated feed, water, hands, veterinary instruments or grooming tools. A stall or van recently used to house or transport a horse that is shedding the organism may also be a source of infection.
Classic signs of the disease include sudden onset of fever as high as 106 degrees F, thick yellow nasal discharge, and swollen lymph nodes under the jaw. Because strangles is so contagious, strict measures to control its spread must be taken. Without control measures, a strangles outbreak will ultimately affect all susceptible horses, last longer, and have a greater chance of leading to complications.
Contact your veterinarian to learn more about this disease and how to prevent it.
