[The effect of gram-negative bacteria lipopolysaccharides on the development of Rauscher leukosis in BALB/c mice].
The dose-dependent action of Shigella sonnei lipopolysaccharide (LPS) on the development of acute erythroleukocytosis, as well as Rauscher chronic myeloid and lymphoid leukosis, in BALB/c mice sensitive to Rauscher virus was shown. Bordetella pertussis LPS in the doses used in this investigation stimulated the development of both acute erythroleukosis and chronic myeloid and lymphoid leukosis in BALB/c mice infected with Rauscher virus. Lipid A isolated from B. pertussis LPS was found to produce a stimulating effect on the development of Rauscher leukosis in mice. After the treatment of B. pertussis LPS with polymyxin B blocking lipid A no stimulating effect of B. pertussis LPS on the development of Rauscher leukosis was observed. A suggestion is made that lipid A is the active principle contributing to the stimulation of the development of Rauscher leukosis in BALB/c mice.
