Protective properties of synthetic peptides of outer meningococcal membrane.

摘要

Peptide fragments of conservative sites of PorA, OpaB, and NspA proteins of the outer membrane of serogroup B meningococci were synthesized. These peptides caused a pronounced protective effect in immunized mice infected with virulent homologous and heterologous strains of serogroups B and A meningococci. The protective effect appreciably increased, if the studied peptides were associated in a polycomponent preparation, which can be used in the construction of meningococcal bivalent B+A vaccine.
