Extended-spectrum β-lactamase (ESBL)- and plasmid-encoded ampC (pAmpC)-producing Enterobacteriaceae might spread from farm animals to humans through food. However, most studies have been limited in number of isolates tested and areas studied. We examined genetic relatedness of 716 isolates from 4,854 samples collected from humans, farm animals, and foods in Sweden to determine whether foods and...

The resistance of pathogenic bacteria to antibiotics is increasing due with incorrect doses, wrong diagnostics, and the target. Bacteria that have been resistant several are called multi-drug organisms (MDRO) bacteria. Bacterial some requires alternative herbal treatments, one which Chromolaena odorata L. Research must therefore be conducted on antibacterial activity ethanol extract fraction C....

background :  pathogenic bacteria because of beta-lactam antibiotic resistance genes are dangerous to society. this resistance due to esbl genes, plasmids and transposons that by receiving or mutation occurs. the most important factor beta-lactam antibiotic resistance is beta lactamase enzymes. the purpose of this study was to evaluate the frequency of hospital opportunistic pathogenic bacteria...

BACKGROUND/AIM The aim of this study was to determine the prevalence of fecal carriage of extended-spectrum beta-lactamase (ESBL)-producing bacteria, enzyme types, and risk factors affecting colonization. MATERIALS AND METHODS A total of 576 stool samples from outpatients were examined between October 2012 and May 2013. Screening was done with selective EMB plates. ESBL were detected by doubl...

BACKGROUND & OBJECTIVES Extended spectrum beta lactamases (ESBLs) have been observed in virtually all the species of family Enterobacteriaceae. The enzymes are predominantly plasmid mediated and are derived from broad-spectrum beta lactamase TEM-1, TEM-2 or SHV-1 by a limited number of mutations. This study was undertaken to characterize ESBL producers among Escherichia coli and Klebsiella pneu...

OBJECTIVES Plasmid-mediated AmpC beta-lactamase-producing (pAmpC) Enterobacteriaceae are increasing worldwide, difficult to identify and often confounded with extended-spectrum beta-lactamase (ESBL) producers. The low prevalence precludes routine universal admission screening. Therefore, we evaluated potential risk factors for carriage of pAmpC-producing Enterobacteriaceae that would allow targ...

BACKGROUND AND OBJECTIVES The emergence of extended-spectrum β-lactamase (ESBL)-producing Shigella spp. is of increasing clinical concern specially in children worldwide. The aim of this study was to investigate the occurrence of extended-spectrum β-lactamase producing Shigella spp. in Tehran, Iran. MATERIALS AND METHODS The study included all Shigella isolates recovered from pediatric patien...

Urinary tract infections are gaining much importance among community acquired infections. Poor personal hygiene may act as a contributory factor in such frequent developing countries. The condition becomes serious with antimicrobial resistance uropathogens. Specifically, surge of Extended Spectrum beta Lactamase (ESBL) producers poses concern the available treatment options. Present work was ai...

Urinary tract infections (UTIs) due to extended-spectrum-β-lactamase (ESBL)-producing Enterobacteriaceae in children are becoming more frequent, and they are commonly treated initially with a second- or third-generation cephalosporin. We developed a murine model of ascending UTI caused by ESBL-producing Escherichia coli. Using this model, we investigated the renal bacterial burden, interleukin-...

Abstract Background The prevalence of antimicrobial resistance (AMR) among Gram-negative bacteria is alarmingly high. Reintroduction colistin as last resort treatment in the infections caused by drug-resistant has led to emergence and spread resistance. This study was designed determine drug-resistance beta-lactamase-producing strains Escherichia coli Klebsiella pneumoniae, isolated from clinic...
