The Michigan Department of Agriculture and Rural Development (MDARD) has received a reported case of strangles in a 17-year-old miniature horse gelding from Oakland County. The case was discovered unexpectedly when the animal was sent to MSU’s Large Animal Clinic with signs of head trauma. While undergoing further testing, clinic staff discovered some mucopurulent discharge (“pus”), which was sampled and subsequently cultured positive for the bacteria that causes strangles.

In this case, it is believed that the horse was infected some time ago and did not fully clear the disease. The animal was not vaccinated against the disease, and it is being isolated and treated at MSU.
