Subtyping, a form of polymorphism, is when calling code can be agnostic as to whether an object belongs to a parent class or one of its descendants. For example, a function might call make_full_name() on an object, which will work whether the object is of class Person or class Employee.
The history may include inappetance, or loss of appetite, lethargy, and fever. Severely affected horses may have a history of high fever (105 â 106Â° F), depression, ventral edema, weight loss, ataxia, or incoordination, and epistaxis, or nosebleed.he virus is transmitted primarily by blood-feeding horseflies and deerflies. Infection with EIAV results in recurring, cyclic episodes of fever, lethargy, thrombocytopenia, or low platelets, anemia, and in some cases, weight loss, ventral edema, petechiation, or pinpoint bleeding in the skin, hemorrhage, and death.
This decreased sensitivity may partially explain the lack of clinical signs often seen in sick neonates with corneal ulcers. Corneal healing in the horse. The thickness of the equine cornea is 1.0 to 1.5 mm in the center and 0.8 mm at the periphery.yelid melanomas are found in grey horses, with Arabians and Percherons also at increased risk. Melanomas may be single or multiple. Treatment is cimetidine, surgical excision and/or cryotherapy. Sarcoids are solitary or multiple tumors of the eyelids and periocular region of the horse.
