Enterococcus faecalis

Objective. To evaluate the ability of bovhyaluronidaze azoximer to destroy biofilms formed by clinical strains of microorganisms. Materials and Methods. The study included 50 clinical strains of Staphylococcus aureus (n = 25), Staphylococcus epidermidis (n = 6), Enterococcus faecalis (n = 8), Escherichia coli (n = 9), Candida albicans (n = 2). Antimicrobial susceptibility testing was performed using broth microdilution method. Biofilm formation culturing in presence of antibiotics, or bovhyaluronidaze azoximer, or their combinations was assessed in Mueller-Hinton broth and brain heart broth in 96-well plates.

Objective. To study virulence genes in E. faecium and E. faecalis isolated from the blood cultures of patients with hematological diseases. Materials and Methods. Virulence genes were studied in E. faecium and E. faecalis strains isolated from blood culture from hematological patients in four Russian hospitals (2002–2020). Susceptibility to vancomycin was determined by broth microdilution method (CLSI, 2022). Virulence genes (esp, hyl, asa1, cylA and gelE) in E. faecium and E.
