Effect of a corpuscular polyvalent Pseudomonas aeruginosa vaccine on the proliferation and differentiation of hematopoietic stem cells and erythropoiesis

: P. aeruginosa corpuscular polyvalent vaccine stimulates hematopoiesis in sublethally stimulated mice. The stimulating effect is dose-dependent. The most effective method of immunization is the intravenous injection of the vaccine. The degree to which the stimulation of hematopoiesis is manifested varies in different strains of mice. The stimulation of hematopoiesis is not linked with an increase in the content of erythropoietin. P. aeruginosa polyvalent corpuscular vaccine and monovaccine, prepared from P. aeruginosa strain 1313 and incorporated into the polyvalent vaccine, protect lethally irradiated mice in the postradiation survival test.
