[Cell-free Pseudomonas vaccine. IV. Laboratory trials of the effectiveness of experimental Pseudomonas vaccines].
Partially purified water-soluble cellular protein antigens have been obtained from 2 newly isolated P. aeruginosa strains and 1 museum P. aeruginosa strain, belonging to immunotypes 2, 3 and 7, by the method of preparative ultracentrifugation. Such trivalent P. aeruginosa vaccine (PV) has proved to be effective in direct and cross experiments of the active protection of mice. The method of ultrafiltration has been used to prepare monovalent PV from a newly isolated strain belonging to immunotype 3/7. This monovalent PV has been found to stimulate immunity to infection with homologous or heterologous P. aeruginosa strains in mice. The comparison of the results obtained in the study of PV prepared by the methods of ultracentrifugation and ultrafiltration suggests that both these methods for the isolation and purification of P. aeruginosa protective protein antigens are equally effective.
