Immunization against anthrax with aromatic compound-dependent (Aro-) mutants of Bacillus anthracis and with recombinant strains of Bacillus subtilis that produce anthrax protective antigen.

Abstract excerpt

The safety and efficacy of five prototype, live anthrax vaccines were studied in Hartley guinea pigs and CBA/J and A/J mice. Two of the strains, Bacillus anthracis FD111 and FD112, are Aro- mutants derived by Tn916 mutagenesis of B. anthracis UM23-1. Bacillus subtilis PA1 and PA2 contain a recombinant plasmid, pPA101 or pPA102, respectively, that carries the gene from B. anthracis encoding synthesis of protective...
