 Abstract


A 27-year-old woman suffered from anaphylaxis after being stung by Solenopsis invicta ants while she was handling wood from South America. The patient reported no previous adverse reactions to stings by other hymenopteran species. Intradermal skin tests
with hymenoptera venom (Vespula vulgaris, Polistes species, Apis melifera) were negative. Serum specific immunoglobulin (Ig) E yielded positive results for S invicta (5.28 kU/L) and negative results for A melifera, Ves v 5 and Pol a 5. Immunodetection assays showed the presence of serum IgE against the Sol i 2 allergen. The patient had probably been stung previously although inadvertently by red fire ants while she handled infested wood from South America, and precautionary measures are thus advisable when this material is to be handled.
To our knowledge this is the first case of anaphylaxis from red fire ant stings reported in Europe.

Key words: Red fire ant venom. Allergens. Anaphylaxis. Solenopsis invicta. Hymenoptera. Europe.
