Current study was conducted to determine prevalence and antimicrobial susceptibility patterns, ESBL, AmpC and carbapenemase- producers among clinical isolates of Enterobacteriaceae. Three hundred and seven non-duplicative clinical isolates were collected from hospitalized patients in five medical centers in Azerbaijan, Iran. Initial screening for β-lactamase production was performed using disc ...

urinary tract infections (utis) are significant health problem, with escherichia coli as the primary pathogen in proximally 80% of cases. the adhesion of e coli to the host cell can be influenced by cell surface hydrophobicity (csh) and is an important factor for the development of infections. this study was conducted to find the relation between csh and one of the adhesions (mannose resistant ...

Introduction: Extended spectrum β-lactamase producing gram negative bacilli has emerged and spread worldwide as an important cause of urinary tract infections indicates a major threat. The study aimed to determine the prevalence multidrug resistant extended beta-lactamase bacterial uropathogens among females in tertiary level hospital. Methods: A hospital-based cross-sectional was conducted Pok...

background extended-spectrum beta-lactamases (esbls) are a group of enzymes that hydrolyze antibiotics, including those containing new cephalosporins, and they are found in a significant percentage of escherichia coli and klebsiella pneumoniae strains. with the widespread use of antibiotics, difficulties with infection therapy caused by drug resistant organisms, especially those that have acqui...

We characterized 12 clinical isolates of Klebsiella oxytoca with the extended-spectrum β-lactamase (ESBL) phenotype (high minimum inhibitory concentration [MIC] values of ceftriaxone) recovered over 9 months at a university hospital in Japan. To determine the clonality of the isolates, we used pulsed-field gel electrophoresis (PFGE), multi-locus sequence typing (MLST), and PCR analyses to detec...

Objective. To study the sensitivity level of extended spectrum beta-lactamase-producing Enterobacteriaceae to Carbapenems (Imipenem, Ertapenem) marketed in Morocco and discusses the place of Ertapenem in the treatment of extended spectrum-beta-lactamase-producing. Materials and Methods. A retrospective study of 110 extended spectrum beta-lactamase-producing Enterobacteriaceae. Isolates obtained...

Introduction: Bacterial resistance to β-lactam antibiotics has risen dramatically, with extended spectrum βlactamase (ESBL) contributing to this increase. Early identification of ESBL production is becoming increasingly important. Methodology: A total of 367 consecutive, urine samples from patients suspected to have UTI, were processed. All Escherichia coli and Klebsiella species isolated in si...

To identify the reservoirs of shiga toxin-producing Escherichia coli O157, sensitive detection andisolation methods are necessary. The sensitivity of traditional culture methods can be improved significantlyby the inclusion of an immunoconcentration step, resulting in less false-negative results. In this study,enrichment procedure and immunomagnetic separation (IMS) were compared for use in con...
