Objective: To document the incidence of high-level gentamicin resistance (HLGR) in enterococcal isolates at Johannesburg Hospital.
Design: Survey of laboratory isolates.
Setting: Academic hospitals. BACTERIAL STRAINS: Consecutive samples of enterococcal isolates.
Main outcome measure: The incidence of HLGR in enterococcal isolates.
Results: The incidence of HLGR was 26.5% of Enterococcus faecalis isolates and 20% of E. faecium isolates grown during the study period.
Conclusions: High-level gentamicin resistance is common among enterococci isolated at Johannesburg Hospital, and this observation must be considered in defining strategies for the management of invasive enterococcal infections in the future.
