Abstract

In these studies, a serological correlate of protection against anthrax was identified in New Zealand white (NZW) rabbits that had been given one or two injections of various amounts of recombinant protective antigen (rPA) combined with aluminum hydroxide adjuvant (Alhydrogel). Rabbits were subsequently challenged by the aerosol route with spores of the Ames isolate of Bacillus anthracis. Results suggested that the antibody response, as determined by the quantitative anti-rPA IgG ELISA and toxin neutralizing antibody (TNA) assay, were significant predictors (P<0.0015) of protection against a B. anthracis aerosol spore challenge in rabbits.
