title: [Mitogenic action of the liquid phase of a microbial suspension of Bordetella pertussis].
abstract: The suspension of B. pertussis cells in 0.15 M NaC1 solution, used for the preparation of corpuscular pertussis vaccine contains components loosely bound to microbial cells and producing pronounced mitogenic effect on mouse splenocytes at a concentration of 10 micrograms/ml. The mitogenic activity of B. pertussis is due to complex substances (lipopolysaccharide, protein, nucleic acids) with a wide range of molecular weights (70,000 to greater than 400,000). The mitogenic factor showing no leukocyte-stimulating and protective activity has been isolated by sedimentation with ammonium sulfate and gel filtration on Sephadex G-200. The mitogenic activity of B. pertussis lipopolysaccharide in the blast transformation test has been confirmed.
