IgA1-protease allocated from the culture N. meningitidis serogroup A. As original materials were used three different intermediate products of vaccine production: cultural fluid, cetavlon supernatant and cetavlon precipitate. IgA1-protease was used to evaluate their protectivity and immunogenity. It was shown, that isolated IgA1 protease from the meningococcus serogroup A is able to protect mice, infected by meningococcus serogroup B.IgA1 ΠΏΡΠΎΡΠ΅Π°Π·Π°, Π²ΡΠ΄Π΅Π»Π΅Π½Π½Π°Ρ ΠΌΠ΅ΡΠΎΠ΄Π°ΠΌΠΈ ΠΏΡΠ΅ΠΏΠ°ΡΠ°ΡΠΈΠ²Π½ΠΎΠΉ Ρ

Microbial capsular polysaccharides for many years provided a highly practical public health vaccines for preventing meningococcal, pneumococcal and Haemophilus influenza infection, and typhoid fever. Their application in the form of conjugates with protein carriers eliminate the gap in protection against these infections in children under one year. Extremely promising turned out offered us a new generation of vaccines, which have synthetic peptides conjugated to a meningococcal polysaccharide. Thus, new approaches to the solution of the problem of meningococcal disease vaccination serogroup B were open. In recent years, Russian researchers first suggested to use IgA1 protease (one of the major virulence factors of microbes and almost identical for mentioned below infections) for prevention of such diseases as meningococcal of all serogroups, pneumococcus and hemophilia infections. Patented processes for producing of the vaccine define domestic priority of its production and use.ΠΠΈΠΊΡΠΎΠ±Π½ΡΠ΅ ΠΊΠ°ΠΏΡΡΠ»ΡΠ½ΡΠ΅ ΠΏΠΎΠ»ΠΈΡΠ°Ρ

Isolation and determination of the activity of IgA1 protease from Neisseria meningitidis
A method of the isolation and purification of IgA1 protease from a culture of Neisseria meningitidis serogroup A has been developed. Three inactivated intermediates of the production of the meningococcal vaccine, a culture liquid, as well as a supernatant and precipitate obtained by the precipitation of bacterial cells by cetavlon, served as a starting material. The purity of IgA1 protease was determined by SDS-PAGE. An immunoenzyme assay for determining the IgA1 protease activity has been developed. The yield of the enzyme with a specific activity of 0.5 to 4 million units/mg from 103 g of the cetavlon precipitate (40 l of culture liquid) was about 600 ΞΌg. It was shown that IgA1 protease isolated from serogroup A meningococcus is capable of protecting experimental animals (mice) infected with meningococcus of serogroup B.
