摘要
FIELD: medicine.;SUBSTANCE: invention can be used in manufacturing of vaccines for Streptococcus pyogenes - streptococci of group A (SGA) and Streptococcus agalactiae - streptococci of group B (SGB). Substance of the invention involves development of recombinant DNA pB1 derived from PCR with using chromosomal DNA of strain 090R Ia of serotype SGB, primers Pb1 and Pb2 and following cloning with using expression plasmid pQE-30 in E coli M15. Recombinant DNA pB1 codes recombinant protein PB1 expressing protective properties in relation to specified streptococci which has no enzymatic activity and causes synthesis of anti-Pb1 antibodies expressing protective properties in relation to Streptococcus pyogenes and Streptococcus agalactiae. In the invention there is developed recombinant plasmid DNA pQE-pB1 representing plasmid DNA pQE-30 that bears recombinant DNA pB1, and strain-producer E. coli M15-PB1 enabling to express recombinant protein PB1.;EFFECT: no enzymatic activity of produced recombinant protein allows application as an ingredient of the vaccine for Streptococcus pyogenes and Streptococcus agalactiae.;7 cl, 7 dwg, 4 tbl, 8 ex
