[Application of SP-RIA in the antibody surveillance and serologic diagnosis of epidemic cerebrospinal meningitis].

This paper reports the effectiveness of SP-RIA in the antibody surveillance on population, the observation of immune persistence after vaccination with Group A Neisseria meningococcal capsular polysaccharide vaccine, as well as its use in the serological diagnosis of Neisseria meningitis. In comparison with other assays used presently, SP-RIA might be better and more sensitive for quantitative assay of the antibody. The results showed the practical value of SP-RIA in the study of epidemiology and serology of epidemic cerebrospinal meningitis.
