Plain-English summary
A 10-year-old pony sadly passed away just five days after showing signs of a nervous system problem. A thorough examination after death revealed a small yellowish area in the brain, indicating damage. Under the microscope, the brain showed signs of inflammation and cell death. The findings included tiny organisms that looked like those responsible for equine protozoal myeloencephalitis, a serious disease affecting horses. Unfortunately, the treatment options for this condition were not effective in saving the pony.
Abstract
A 10-year-old pony died 5 days after the onset of a nervous disorder. Necropsy revealed a yellowish area of discoloration (1.5 by 1 cm) in the medulla oblongata. Microscopically, necrosis and nonsuppurative myeloencephalitis were found in the medulla oblongata. Immature and mature meronts (25 by 10 microns) were seen in neural tissue and in capillaries of the brain stem. Organisms were similar structurally to those seen in equine protozoal myeloencephalitis of horses.
