A 44 yo man receives penicillin V from his GP for tonsillitis. He becomes very unwell with a rash, flushing, wheezing and he collapses. He is told that he has had an anaphylactic reaction to penicillin. This type of allergic reaction is mediated by which one of the following antibodies? - IgA - IgD - IgE - IgG - IgM

IgE IgA is found in mucosal areas, such as the gut, respiratory tract and urogenital tract, and prevents colonization by pathogens, it is also found in saliva, tears, and breast milk.

IgM is the most primitive antibody and eliminates pathogens in the early stages of B cell-mediated (humoral) immunity (primary response) before there are sufficient IgG. IgE is in response to parasites and is responsible for anaphylaxis.
