The effects of different carbon dioxide concentrations on the growth of virulent anthrax strains : pathogenicity and immunity tests on guinea pigs and sheep with anthrax variants derived from virulent strains
(1) Virulent anthrax strains grew mucoid and produced avirulent rough dissociants on serum agar, in a number of different carbon dioxide concentrations. (2) A relatively small close of avirulent spores immunized sheep against anthrax. (3) The immunizing power of the avirulent rough strains was
not associated with the carbon dioxide concentration in which they developed.
