[Effect of Neisseria meningitidis on the humoral response of various strains of mice immunized with ram erythrocytes]. 1984

A B Petrov, and Iu V Filippov, and B F Semenov

The capacity of heat-killed meningococci and the polysaccharide-protein-lipopolysaccharide fraction ( PPLF ) isolated from the microbial cell wall for changing nonspecific immunological reactivity was studied. In this investigation CBA mice with high response and C57BL/6 mice with low response to sheep red blood cells (SRBC) were used. Heat-killed N. meningitidis, serogroup A, and PPLF , serogroups A and B, were found to enhance and suppress humoral response to the heterologous antigen. The effect of modulation depended on the dose of the antigen, the serogroup of meningococci, the scheme of the experiment and the strain of mice. The immune response of the vaccinated animals to the heterologous antigen was characterized by the following stages: the state of the adjuvant effect was replaced by the state of temporary immunodeficiency and then by enhanced response to SRBC.

UI	MeSH Term	Description	Entries
D007114	Immunization	Deliberate stimulation of the host's immune response. ACTIVE IMMUNIZATION involves administration of ANTIGENS or IMMUNOLOGIC ADJUVANTS. PASSIVE IMMUNIZATION involves administration of IMMUNE SERA or LYMPHOCYTES or their extracts (e.g., transfer factor, immune RNA) or transplantation of immunocompetent cell producing tissue (thymus or bone marrow).

D008810	Mice, Inbred C57BL	One of the first INBRED MOUSE STRAINS to be sequenced. This strain is commonly used as genetic background for transgenic mouse models. Refractory to many tumors, this strain is also preferred model for studying role of genetic variations in development of diseases.

D009345	Neisseria meningitidis	A species of gram-negative, aerobic BACTERIA. It is a commensal and pathogen only of humans, and can be carried asymptomatically in the NASOPHARYNX. When found in cerebrospinal fluid it is the causative agent of cerebrospinal meningitis (MENINGITIS, MENINGOCOCCAL). It is also found in venereal discharges and blood. There are at least 13 serogroups based on antigenic differences in the capsular polysaccharides; the ones causing most meningitis infections being A, B, C, Y, and W-135. Each serogroup can be further classified by serotype, serosubtype, and immunotype.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
