Plain-English summary
A 14-year-old Quarter Horse gelding in western Montana developed a serious neurological condition caused by a larva from a warble fly, known as Hypoderma bovis. The horse showed signs of trouble walking, circling to the left, tilting its head to the right, partial paralysis on the right side of its face, and poor vision in its right eye. Just two and a half hours after the symptoms were first noticed, the horse collapsed and had to be put to sleep. A significant amount of bleeding was found in the right side of the brain, but there was no tissue death or major inflammatory response. Unfortunately, the treatment did not work, and the horse could not be saved.
Abstract
Acute neurologic disease associated with intracranial migration of a first instar larva of a warble fly, Hypoderma bovis (Linnaeus), was observed in a 14-year-old Quarter Horse gelding in western Montana. The disease was characterized by incoordination of gait, circling to the left, head tilt to the right, partial paralysis of the right side of the face, and impaired vision in the right eye. Two and one-half hours after it was first noticed sick, the horse collapsed and was euthanized. Massive hemorrhage unaccompanied by necrosis or significant cellular response was present in the right side of the midbrain and pons.
