Humoral immune response in chinchillas to the capsular polysaccharides of Streptococcus pneumoniae. 1983

G S Giebink, and G Schiffman

Vaccines made from the capsular polysaccharides of Streptococcus pneumoniae have been shown to reduce the incidence of pneumococcal disease in certain populations and have recently been evaluated for their ability to elicit protection against experimental pneumococcal otitis media in a chinchilla model. In this study, chinchillas were vaccinated with a dodecavalent preparation of pneumococcal capsular polysaccharides (PCP) to obtain more information on the immunogenicity of these polysaccharide antigens. All 12 PCP types elicited an antibody response, but the optimum PCP dose and the kinetics of the antibody response varied among types. Immunological paralysis was demonstrated with an immunogenic dose of PCP after primary immunization with a large PCP dose (25 micrograms or more). Pertussis vaccine acted as neither an immunoadjuvant nor an immunosuppressant in the serum antibody response to type 7F PCP in chinchillas.

UI	MeSH Term	Description	Entries
D007700	Kinetics	The rate dynamics in chemical or physical systems.
D010567	Pertussis Vaccine	A suspension of killed Bordetella pertussis organisms, used for immunization against pertussis (WHOOPING COUGH). It is generally used in a mixture with diphtheria and tetanus toxoids (DTP). There is an acellular pertussis vaccine prepared from the purified antigenic components of Bordetella pertussis, which causes fewer adverse reactions than whole-cell vaccine and, like the whole-cell vaccine, is generally used in a mixture with diphtheria and tetanus toxoids.
