A generalized allergic reaction called
serum sickness is caused by an injection of serum or serum proteins from one species of
animal into another. The immune system of the recipient reacts against it, producing an illness characterized by itching, fever, joint pain, skin eruptions, and extensive swelling (edema). Serum sickness was more common in the past, when certain bacterial infections were treated with animal
serums, than today, when antibiotics have mainly replaced serums.
