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.
Lyme disease is a bacterial disease of humans and animals transmitted by ticks. In horses, the most common clinical sign is arthritis, but horses can also experience lameness, neurologic disease, eye disease, and dermatitis.ymptoms in horses can range from no signs of disease to depression, trouble walking or paralysis, convulsions, or other neurologic signs and death. Horses are dead-end hosts to EEE, WEE, and SLEV, which means that they usually do not spread these viruses to other animals or humans.
