Characterization and Antimicrobial Susceptibility Patterns of Species Isolated from Nosocomial Infections in a Saudi Tertiary Care Hospital over a Ten-Year Period (2012-2021).

Introduction: The Enterococcus genus is a common cause of nosocomial infections, with vancomycin-resistant enterococci (VRE) posing a significant treatment challenge.

Method: This retrospective study, spanning ten years (2012 to 2021), analyzes antimicrobial susceptibility patterns of species from clinical samples in a Saudi Arabian tertiary care hospital.

Result: A total of 1034 Enterococcus isolates were collected, 729 from general wards and 305 from intensive care unit (ICU) patients.
