Antimicrobial Resistance among Enterococci Isolated from the First Bethune Hospital

Enterococci have become an important cause of nosocomial and community-acquired infections since the late 1980s. The present study aimed to evaluate the antibiotic resistance profiles of Enterococci isolated in the First Bethune Hospital. Disk diffusion method was used to study the antimicrobial resistance. The data were analyzed by WHONET 5 software according to Clinical and Laboratory Standards Institute (CLSI). The majority of 1446 strains of Enterococci were collected from urine (640, 44.3%), sputum (315, 21.8%), secretions and pus (265, 18.3%). The percentage of high-level aminoglycoside resistance (HLAR) in Enterococcus faecalis and Enterococcus faecium were 71.2% and 87.1%, respectively. The Enterococci isolates were sensitive to vancomycin. Enterococci strains were frequently resistant to multiple antibiotics. Antimicrobial resistance of Enterococcus faecium was more serious than that of Enterococcus faecalis. These results suggest that surveillance of antimicrobial resistance among Enterococci is necessary.
