Abstract


Due to the fact that an inactivated anthrax vaccine may lark its immunogenicity and stability of immunogen a number of spore vaccines were exclusively used worldwide. In these studies a number of important factors were emphasized to achieve the following: selection of non or less allergic strain of anthrax bacillus, capsulation of bacteria. obtaining of non sporulatinng but vegetative organisms, adequate inactivation of B. anthraccis by means of formalin, adsorption of immunogen to aluminum hydroxide gel.
Non or less allergic strains of anthrax bacillus which is inactivated with formalin was selected by a hyperimmunization and shock test in rabbits. Obtaining capsular material and vegetative immunogen, a virulent anthrax organisms were cultivated on sodium bicarbonate medium with of without adding of l-alanine in which B, anthracis grew luxuriantly without forming spores. Inactivation was carried out at 37℃ water bath for 3 days after the bacterial culture was mixed with formalin, in a final concentration of two per cent of formalin. Aluminum hydroxide gel was added to the mixture of anthrax and blackleg bacterin. Vaccines were injected guinea pig via subcutaneous or intramusoular route and challenged after three weeks and the possibilities of protection was tested.
Throughout the studies. the above mentioned vaccines possibly protected the vaccinated guinea pigs more than 80 per cent compared to that of the controls. This experimental results strongly suggest that the vaccine may possibly applicable to bovine.
