Introduction: Enterobacteriaceae produce the Extended-Spectrum Beta-Lactamases which is considered as an important resistant mechanism of beta-lactam antibiotics. The resistance to beta-lactam antibiotics is the main problem in the bacterial infections therapy. The prevalence of these enzymes changes in different geographical areas and with time. The present study aims to explore the frequency ...

background escherichia coli (e. coli) species are able to produce extended-spectrum β-lactamases (esbls) that cause high resistance to the beta-lactam antibiotics. therefore, determining the antibiotic susceptibility patterns in resistant organisms is necessary for suitable therapeutic approaches. patients and methods totally, 260 clinical isolates of e. coli were collected from hospitals in te...

background & objectives:extended-spectrum-b-lactamase (esbl)-producing strains of klebsiella pneumoniaare an important cause of many serious infections in hospitalized and nonhospitalized patients and delayed treatment of these infections in crease chance of death in patients. this study was performed to determine the prevalence of esbl-producing k. pneumonia and to evaluate the frequency o...

The occurrence of extended-spectrum beta-lactamases-producing bacteria is an important public health issue. The aim of this study was to investigate phenotypic and genotypic characteristics regarding the presence of extended spectrum β-lactamase ctx-m, per and ver producing Escherichia coli isolated from raw dairy samples. For this purpose, E. coli were isolated from 247 raw dairy samples (milk...

 Background and purpose: Escherichia coli (E.coli) is the most common cause of urinary tract infection. The treatment strategy has been hampered by the emergence of broad-spectrum beta-lactamase-producing E.coli and its resistance to most antibiotics. Bacteriophages are suggested as an alternative treatment option. This study aimed at evaluating the lytic activity of isolated phage from unpaste...

Antibiotic resistant ?-lactamases are diverse and complex enzymes produced by most of the Gram-negative bacteria that mediated number plasmids. The impact these has posed a major threat to health sectors challenged available treatment options for both community hospital acquired infections. These include uncomplicated severe life-threatening Moreover, with resistance cephalosporin drugs MDR str...
