Antimicrobial resistance surveillance of Klebsiella spp. isolated from the First Bethune Hospital

摘要

Klebsiella spp. are opportunistic pathogens which frequently cause community and nosocomial infections. The present study aimed to evaluate the antibiotic resistance profiles of Klebsiella spp. isolated from 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 3149 strains of Klebsiella spp. were collected from sputum (1890, 60.0%) , blood (378, 12.0%) and secretions (315, 10.0%) . The percentage of extended-spectrum β-lactamases (ESBLs) in Klebsiella spp. was 53.8% (1694/3149). Klebsiella spp. strains were frequently resistant to multiple antibiotics. Antimicrobial resistance of ESBL-producing Klebsiella spp. was more serious than that of non-ESBL-producing isolates. The results suggest that surveillance of antimicrobial resistance in Klebsiella spp. is necessary.
