| Abstract: | Monovaccines were prepared from seven P. aeruginosa immunotypes (according to Fisher's classification) and three P. aeruginosa production strains belonging to immunotypes 2, 3, and 7. The immunogenic potency of these monovaccines was studied in direct and cross experiments on the active protection of mice. The study revealed that the monovaccines prepared from P. aeruginosa of seven immunotypes possessed both specific and cross protective activity. Protective cross activity was revealed also in the vaccines prepared from the production strains. When tested in mice challenged with the corresponding homologous strains, the monovaccines prepared from immunotypes 2, 3, 4 and 7 proved to possess higher immunogenic potency than monovaccines prepared from immunotypes 1, 5 and 6. |
