| Abstract: | The safety and immunological activity of P. aeruginosa vaccine were experimentally evaluated. The vaccine was prepared on the basis of the antigens of P. aeruginosa extracellular slime which was accumulated in medium K-4, obtained with the use of original technology. The immunization of animals with P. aeruginosa vaccine induced the synthesis of antibodies. The introduction of the vaccine in 2 or 3 injections resulted in a high level of antibody formation, differing with the use of various strains. Hyperimmune sera, obtained by the multiple immunization of rabbits with P. aeruginosa vaccine, ensured high protection of mice from P. aeruginosa infection. The vaccine proved to be safe when evaluated in experiments of acute and chronic toxicity, made on laboratory animals. |
