Abstract

A comparative study was made of the effect of anti-bee venom phospholipase A2 serum and antir-bald face hornet venom serum on the activity of phospholipase A2 present in yellow hornet, yellow jacket, bald face hornet, and honeybee venoms. Activity of phospholipase A2 present in the venoms was measured titrimetrically using egg yolk dispersion as the substrate. Antiserum against pure bee venom phospholipase A2 activity completely suppressed bee venom phospholipase A2 activity but failed to inhibit phospholipase A2 activity in yellow jacket, yellow hornet, and bald face hornet venoms. Anti-bald face hornet venom serum suppressed the activity of phospholipase A2 present in the four insect venoms with the inhibitory effect decreasing in the order: bald face hornet > yellow hornet > yellow jacket > honeybee. A combination of immunoelectrophoresis and immunodiffusion techniques gave indication of common antigenic sites in a component of yellow hornet venom and a component of bald face hornet venom. The results suggest that IgG antibodies against pure bee venom phospholipase A2 may not give any protection against the reaction(s) due to the phospholipase A2 in yellow hornet, yellow jacket, and bald face hornet venoms, while antibodies against bald face hornet venom phospholipase A2 may give some cross-protection.
