Abstract

We tested antimicrobial susceptibility of retrospective collection of clinical strains group С and G streptococci (69 strains including 58 strains of Streptococcus dysgalactiae subspecies equisimilis and 11 strains of Streptococcus anginosus). Susceptibility testing was performed by discdiffusion method according to Russian national guidelines. Penicillins, as well as cephalosporins and vancomycin were active against all tested strains. Susceptibility of S. anginosus and S. dysgalactiae subspecies equisimilis to macrolides was from 5.8% to 26.1%, to tetracyclines – from 10.1% to 18.8%, respectively.
