The rapid expansion of antibiotic-resistant pathogenic bacteria is perceived as a global threat to humanity, which causes significant damage to human health and leads to huge economic losses. Antibiotic resistance is a multifaceted phenomenon, one of …

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.
