title: Immunological studies on bee-keepers: specific IgG and subclass typing IgG against bee venom and bee venom components.
abstract: Specific IgE antibodies against bee venom and its components were studied in 23 bee-keepers. The highest IgG serum levels were observed for whole bee venom followed by phospholipase A. The serum levels of specific IgG antibodies against melittin and MCD-peptide were lower, the lowest serum levels being observed for apamin. After a 5 month absence from bee-keeping a fall in the serum levels of IgG antibodies was observed in all the bee-keepers studied. The investigation of the IgG subclass antibodies 1-4 against bee venom and phospholipase A demonstrated the highest serum levels for IgG 4 and IgG 2, the lowest levels were observed for IgG 1. The lowest IgG serum levels were associated with the least effective protection to bee stings. These findings support the concept that specific IgG antibodies prevent the development of allergic symptoms after bee sting.
