Autor: S A, Bitko, N I, Briko, L O, Dynga

Publikováno v: Zhurnal mikrobiologii, epidemiologii i immunobiologii. (2)

The study of the kinetic curves of the lysis of group A S. pyogenes cell-walls (cells), serovars 29 and 12 M, variants M+ and M-; with endo-N-acetyl-muramidase revealed that the kinetics of the lysis of virulent and avirulent strains was different: v

[The biochemical and immunological properties of group A type M 29 streptococci cultured in the presence of a bovine blood serum preparation]

Autor: S A, Bitko, L O, Dynga

Publikováno v: Zhurnal mikrobiologii, epidemiologii i immunobiologii. (5)

The influence of the preparation of cattle blood serum on group A streptococcus, type M 29, has been studied. The study has revealed that the addition of 17% of dialysis water obtained from a fraction of cattle blood serum to the standard culture med

[A study of the variability of group A type M29 streptococcus on exposure to biologically active substances]

Autor: S A, Bitko, L O, Dynga, N I, Briko

Publikováno v: Laboratornoe delo. (9)

Biologically active substances spermidine and the compounds contained in the low-molecular fraction of cattle blood serum change the phenotype of type 29 group A Streptococcus. Amino acid analysis and enzymatic destruction of cell walls have demonstr

[The physicochemical and biochemical characteristics of the cell walls in M+ and M- variants of Streptococcus group A type 29]

Autor: S A, Bitko, L O, Dynga, A R, Shikhman, Z F, Shmakova, N I, Briko

Publikováno v: Zhurnal mikrobiologii, epidemiologii i immunobiologii. (4)

The amino acid composition of cell walls and surface proteins, isolated from virulent (M+) and avirulent (M-) streptococcal strains (group A, type 29) has been determined by the method of E. H. Beachey et al. The kinetics of the lysis and proteolysis
