[Latent sensitization to bee and wasp venoms]. / Latente Sensibilisierung auf Bienen- und Wespengift.

IgE-RAST with bee and wasp venom was performed on 200 persons without any allergic history. Specific IgE antibodies against bee and/or wasp venom were found in 55 persons (27, 5%); in 14 persons of these against bee, in 29 against wasp and in 12 against bee and wasp venom. Specific IgG antibodies were only found in 16, 4% of the silently sensitizated persons. Therefore, the lack of symptoms in the remainder of this group cannot be explained by the presence of blocking IgG antibodies.
