Symptoms.—Long wooled sheep are more susceptible to this tick as their wool provides shelter for both the tick and its eggs. After shearing the sheep the ticks have a tendency to leave the body and to migrate to the legs or to unshorn lambs where their snouts or trunks pierce the skin which appears to become infected, producing a swelling and inflammation. The infected sheep run, scratch and bite themselves. When these ticks become developed in large quantities, they produce a paleness of the mucous membranes of the eyes, mouth and nose, as the ticks suck large quantities of blood, which produces an anemic condition. The sheep become poor, weak and unthrifty.
Treatment.—Satisfactorily treated by dipping infected sheep in Coal Tar dips or Emulsions of Crude Petroleum. Shearing the sheep has a good effect, but care must be exercised as the ticks then rapidly migrate to the lambs.
