orthopedic infection

Objective. To study effects of bacteriophages on biofilm formation and formed biofilm by S. aureus isolated from patients with orthopedic infection. Materials and Methods. A total of 50 clinical strains of S. aureus were tested. Species identification was performed by MALDI-TOF MS, antibiotic susceptibility – in accordance with the EUCAST v21. Isolates susceptibility to bacteriophages «Sextafag» (Microgen, Russia) was determined by MPA medium. The antibacterial activity of phages against S.

Objective. To evaluate the resistance rate and production of carbapenemases in Klebsiella pneumoniae with phenotypic resistance to carbapenems isolated from patients with orthopedic infection. Materials and Methods. The materials for the study were tissue samples, aspirates and removed orthopedic devices of patients with orthopedic infection at the Vreden Russian Research Institute of Traumatology and Orthopedics, between 2017 and 2019. K. pneumoniae strains were identified in Microlatest by iEMS ReaderMF. These strains were tested for susceptibility to 15 antimicrobial agents by disk diffusion methods, as described by the EUCAST.
