| Abstrakt: |
The immunogenic potency, toxicity, homologous and heterologous protective activity of lipopolysaccharide preparations obtained from serogroup A N. meningitidis (LPS A) were studied in animal experiments. These preparations were shown to possess very high protective activity. The alkaline treatment of native LPS A decreased the toxicity of the preparation almost 20 times and did not affect its immunogenic potency. Detoxified LPS A was capable of protecting mice from fatal meningococcemia resulting from infection with N. meningitidis strains, serogroups A, B and C; the adsorption of the preparation on aluminium hydroxide did not affect its protective activity. In view of the properties of detoxified LPS A revealed in this investigation, it may be regarded as a possible vaccinal preparation. |
