[Characteristics of the mechanism of the development of the epidemic process in meningococcal infection in organized collectives]. 1988

E I Efimov

The specific features of the epidemiology of meningococcal infection in organized groups have been established after comprehensive (epidemiological, microbiological and immunological) studies, evaluated from the viewpoint of the law of the autoregulation of the epidemic process. The studies have revealed the phenomenon of the adaptive biological variability of meningococci with their prolonged reservation due to the transformation of typical bacterial forms of meningococci characterized by strict serogroup specificity and typical fermentative activity into serologically and biochemically undifferentiated forms, capable of prolonged persistence in human populations. The model demonstrating the development of the epidemic process in meningococcal infection in an organized group has been worked out.

UI	MeSH Term	Description	Entries
D007136	Immunoglobulins	Multi-subunit proteins which function in IMMUNITY. They are produced by B LYMPHOCYTES from the IMMUNOGLOBULIN GENES. They are comprised of two heavy (IMMUNOGLOBULIN HEAVY CHAINS) and two light chains (IMMUNOGLOBULIN LIGHT CHAINS) with additional ancillary polypeptide chains depending on their isoforms. The variety of isoforms include monomeric or polymeric forms, and transmembrane forms (B-CELL ANTIGEN RECEPTORS) or secreted forms (ANTIBODIES). They are divided by the amino acid sequence of their heavy chains into five classes (IMMUNOGLOBULIN A; IMMUNOGLOBULIN D; IMMUNOGLOBULIN E; IMMUNOGLOBULIN G; IMMUNOGLOBULIN M) and various subclasses.

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.
