Neutralization of bee venom lethality by immune serum antibodies.

The lethal effects of Africanized honey bee venom depend on the absorption of venom delivered during simultaneous sting attacks by large numbers of bees. The hypothesis that antibodies to whole bee venom and bee venom components could neutralize the lethal effect of bee venom was tested. Antibodies from beekeepers and immunized rabbits were incubated with bee venom and neutralization was studied by survival of intravenously injected mice. Beekeeper serum antibodies were found effective in protecting mice challenged with whole venom, and serum from rabbits immunized with phospholipase A2 (PLA2) was effective in protection against lethal effects of PLA2. Serum antibodies from rabbits immunized with whole venom or melittin were ineffective in neutralizing whole venom in vivo and had low titers in a venom enzyme-linked immunosorbent assay. The results suggest the need for development of more effective methods for raising antitoxic antibodies to bee venom components in other animals as a means of developing an antiserum that would be effective for treatment of human victims of multiple bee stings.

[Preparation of immune serums for the identification of rhinoviruses].

Six schedules of immunization of rabbits, guinea pigs and rats for production of antirhinovirus immune sera were studied. Sera with virus-neutralizing antibody titers of 1:1000 to 1:50,000 were obtained in rabbits immunized into popliteal lymph nodes. The resulting sera had high titers of antibody to cell components and neutralized the cytopathic effect induced by heterologous strains. Sera from which cell components had been absorbed showed strict type-specificity in the neutralization and indirect immunofluorescent tests. A mixture of sera has been shown to be useful for identification of rhinoviruses by the immunofluorescent procedure.
