INTRODUCTION The aim of this study was to determine the prevalence of extended-spectrum beta-lactamase (ESBL) producing Escherichia coli (E. coli), Klebsiella pneumoniae (K. pneumoniae), and Proteus mirabilis (P. mirabilis). In addition, different methods for detection of these enzymes, including the newly introduced CHROMagar ESBL, were evaluated. METHODOLOGY A total of 382 Enterobacteriacea...

conclusions it was the first report on the blactx-m-15 gene emergence in clinical enterobacter spp. in iran. the current study demonstrated the predominant presence of the gene encoding ctx-m-15 among esbl producing enterobacter spp. commonly with a large plasmid, in the setting. background enterobacter spp. is increasingly recognized as an important nosocomial pathogen and implicated in many e...

The presence of extended-spectrum beta-lactamase-producing Escherichia coli (ESBL-E. coli) in food animals is a public health concern. This study aimed to determine prevalence of ESBL-E. coli on pig farms and to assess the effect of reducing veterinary antimicrobial use (AMU) and farm management practices on ESBL-E. coli occurrence on pig farms. During 2011-2013, 36 Dutch conventional pig farms...

Introduction: Extended-spectrum beta-lactamases (ESBLs) are rapidly evolving group of beta-lactamase enzymes commonly produced by the Gram negative bacteria, these enzymes have been derived from TEM and SHV genes by mutations. This study was done to look for TEM and SHV genes in ESBL positive E.coli and K. pneumoniae isolated from the cancer patients suffering with infections and admitted in a ...

Horizontal gene transfer is an important mechanism which facilitates bacterial populations in overcoming antimicrobial treatment. In this study, a total of 120 Escherichia coli and 62 Salmonella enterica subsp. isolates were isolated from broiler chicken farms Alberta. Fourteen serovars identified among isolates. Thirty one percent E. (37/120) multiclass drug resistant (resistant to ? 3 classes...

background: there is a growing concern on the impact of the presence of extended-spectrum β-lactamase (esbl) producing escherichia coli isolated from animals on public health. objectives: the aim of this study was to investigate the presence of three classes of esbl genes in e. coli isolates from sheep and broilers at a slaughter in urmia region, iran. methods: a total of 111 e. coli isolates w...

Despite the fact that selective pressure of antibiotics on wild birds is supposed to be very weak, they are considered potential vectors antimicrobial resistance (AMR). Obligate scavengers such as vultures can present high proportions extended-spectrum cephalosporins (ESC) and multi-drug-resistant (MDR) bacteria, partially due feeding stations provisioned with livestock carcasses from intensive...

BACKGROUND AND OBJECTIVE Nowadays, the presence of extended-spectrum β-lactamases (ESBLs) producing strains in Serratia genus causes the emergence of resistance to many antibiotics. So, the lack of proper diagnosis of ESBLs strains can lead to failure in the treatment. The objective of the present study was to investigate ESBLs production in Serratia strains isolated from the clinical blood sam...

Extended-spectrum β-lactamase (ESBL)-producing Enterobacteriaceae present an ever-growing burden in the hospital and community settings, across all ages and demographics. Infections due to ESBL-containing pathogens continue to be associated with significant morbidity and mortality worldwide. With widespread empiric broad-spectrum β-lactam use creating selective pressure, and the resultant emerg...
