Mechanisms of defense formation against meningococcal infection in mice immunized with synthetic peptides

Immunization of mice with synthetic peptide fragments of conservative sites of meningococcal outer membrane proteins led to defense formation against infection with virulent serogroup A and B Meningococci. The role of cellular immunity in the formation of defense against meningococcal infection after immunization with the peptides and the possibility of stimulating lymphocyte population with these peptides were demonstrated.
