In vitro activity of fosfomycin against extended-spectrum-beta-lactamase-producing Escherichia coli and Klebsiella pneumoniae: comparison of susceptibility testing procedures.
نویسندگان
چکیده
The agar dilution, broth microdilution, and disk diffusion methods were compared to determine the in vitro susceptibility of 428 extended-spectrum-beta-lactamase (ESBL)-producing Escherichia coli and Klebsiella pneumoniae to fosfomycin. Fosfomycin showed very high activity against all ESBL-producing strains. Excellent agreement between the three susceptibility methods was found for E. coli, whereas marked discrepancies were observed for K. pneumoniae.

Introduction: This study is aimed to compare phenotypic test methods and determine antibiotic susceptibility pattern of AmpC beta-lactamase producing uropathogenic Escherichia coli and Klebsiella pneumoniae in clinical isolates. Method: E. coli and K. pneumoniae were identified by standard microbiological procedures. Screening of AmpC beta-lactamase production was done by using cefoxitin disc (...

BACKGROUND The incidence of urinary tract infections (UTIs) caused by extended-spectrum-beta-lactamase (ESBL) producing Escherichia coli (ESBL-EC) and Klebsiella pneumoniae (ESBL-KP) has been on the rise limiting oral treatment options. Fosfomycin was reported to be highly efficacious against these organisms, however, data is lacking in Lebanon and the Middle East. OBJECTIVE To determine the ...

Background & Aims: Considering the importance of drug resistance among pathogenic bacteria and their treatment problems, this study aimed to determine the prevalence of extended-spectrum beta-lactamases (ESBLs), including TEM, SHV, and OXA genes among the isolated Escherichia coli and Klebsiella pneumoniae obtained from urine specimens of kidney transplant patients. Materials & Methods: The ba...
متن کاملThe Prevalence of TEM and SHV Genes among Extended-Spectrum Beta-Lactamases Producing Escherichia Coli and Klebsiella Pneumoniae
Objective(s) Production of extended-spectrum beta-lactamases (ESBLs) by enteric bacteria continues to be a major problem in hospitals and community. ESBLs producing bacteria cause many serious infections including urinary tract infections, peritonitis, cholangitis and intra-abdominal abscess. The aim of this study was to determine the prevalence of ESBLs producing Escherichia coli and Klebsiel...
