Abstract Objects The retrospective study aimed to determine the prevalence rate and
antimicrobial susceptibility of extended-spectrum beta-lactamases (ESBLs)–producing …

Objective To provide data on the molecular characteristics of extended-spectrum β-
lactamase (ESBL)-producing Klebsiella pneumoniae clinical isolates in Japan. Methods A …

Background The extended-spectrum beta-lactamase (ESBL)-producing Klebsiella
pneumoniae has increasingly become a major contributor to nosocomial infections and can …

Klebsiella pneumoniae is an extended-spectrum β-lactamase (ESBL)-producing bacterium
(ESBL-KP). Recently, K. quasipneumoniae and K. variicola were reclassified from K …

The aim of this work was to investigate the epidemiological and genetic characteristics of
ESBL-producing Klebsiella pneumoniae (ESBL-Kp) causing community-onset infections. K …

Objectives The aim of this study was to evaluate the risk factors for pneumonia due to
extended-spectrum β-lactamase-producing Klebsiella pneumoniae (ESBL-KP) and to …

Background Extended-spectrum β-lactamases (ESBLs)-producing Klebsiella pneumoniae is
reported worldwide increasingly. However, studies on ESBLs are still scarce in Ethiopia …

Purpose. Fluoroquinolone resistance (FQ-r) in extended-spectrum β-lactamase (ESBL)
producers is an urgent health concern in countries where ESBL-producing K. pneumoniae …
