Serum sickness in humans is a reaction to proteins in antiserum derived from a non-human animal source, occurring 5–10 days after exposure. Symptoms often include a rash , joint pain , fever , and lymphadenopathy .
They include serum sickness, shortness of breath, and allergic reactions including anaphylaxis. [1] Antivenom is traditionally made by collecting venom from the relevant animal and injecting small amounts of it into a domestic animal. [2] The antibodies that form are then collected from the domestic animal's blood and purified. [2]
A bee sting is the wound and pain caused by the stinger of a female bee puncturing skin. Bee stings differ from insect bites, with the venom of stinging insects having considerable chemical variation. The reaction of a person to a bee sting may vary according to the bee species. While bee stinger venom is slightly acidic and causes only mild ...
It sounds as if Mary has never had allergy treatment for bee stings. So, if she had a strong reaction to one as a child, there is a significant chance her body might respond similarly today.

A type IV hypersensitivity reaction is mediated by T cells that provoke an inflammatory reaction against exogenous or endogenous antigens. In certain situations, other cells, such as monocytes, eosinophils, and neutrophils, can be involved. After antigen exposure, an initial local immune and inflammatory response occurs that attracts leukocytes.
Insect sting allergy is the term commonly given to the allergic response of an animal in response to the bite or sting of an insect. [1] Typically, insects which generate allergic responses are either stinging insects ( wasps , bees , hornets and ants [ 2 ] ) or biting insects ( mosquitoes , ticks ).
Laboratory abnormalities include normal or mild decreases in serum C3, C4, and CH50 levels, and mild proteinuria. In contrast to true serum sickness, renal and hepatic involvement is rare. Significant decreases in serum C3, C4, and CH50, reported in the literature for true serum sickness, are rarely described in serum sickness–like reaction.
