resistance to oxyimino cephalosporins antibiotics in enterobacteriaceae is primarily done by the extended spectrum β-lactamases (esbls). clear identification of risk factors for esbl-producing infections is necessary. therefore, efficient strategies can be developed to decrease outbreak of these infections. the aim of this study was to determine the antibacterial susceptibility and esbls patter...

Objective(s): Escherichia coli is the key pathogen in the family producing ESBL (extended spectrum β-lactamase) and associated with community-acquired infections. Therefore, this study was planned to determine the antibiotic susceptibility pattern of uropathogenic E. coli, prevalence of the ESBL gene group and class 1 integrons.Materials and Methods: Clinical isolates of uropathogenic E. coli w...

patients and methods in this cross-sectional study, a total of 250 isolates (134 e. coli and 116 k. pneumoniae) were collected and antimicrobial resistances to ampicillin, amoxicillin-clavulanic acid, amikacin, gentamycin, ceftriaxone, ceftazidime, ciprofloxacin and imipenem were evaluated by disc diffusion method and confirmed by e-test. moreover, risk factors for mdr e. coli and k. pneumoniae...

BACKGROUND Prevention of infection due to multi-drug resistant organisms is particularly challenging because of the spread of resistant bacteria beyond hospitals into the community, including nursing homes. This study aimed to identify risk factors for the acquisition of a multidrug resistant (MDR) Escherichia coli in a local outbreak. METHODS Study participants were all aged over 65 years. C...

The emergence of plasmid-mediated multidrug resistance (MDR) among enteric bacteria presents a serious challenge to the treatment of bacterial infections in humans and animals. Recent studies suggest that avian Escherichia coli commonly possess the ability to resist multiple antimicrobial agents, and might serve as reservoirs of MDR for human extraintestinal pathogenic Escherichia coli (ExPEC) ...

Background: This study aimed to describe the association between age groups and antimicrobial susceptibility patterns, also integron presence in Escherichia coli and Klebsiella pneumoniae  isolates from Tabriz, Iran. Materials and methods: 140 isolates of E. coli and 150 isolates of K. pneumoniae, both comprising the same number of children and adult isolates were examined for susceptibil...

The aim of this study was to determine the potential association between housing type and multiple drug resistance (MDR) in Escherichia coli and Enterococcus faecalis isolates recovered from 283 laying-hen flocks. In each flock, a cloacal swab from four hens was collected and produced 1102 E. coli and 792 E. faecalis isolates. Broth microdilution was used to test susceptibility to antimicrobial...

BACKGROUND Escherichia coli and Klebsiella pneumoniae are common human pathogens that cause a wide spectrum of infections. Antimicrobial resistance is a basic obstacle in the management of these infections which has different patterns in various regions. OBJECTIVES In this study, the antibiotic resistance patterns and risk factors for multidrug-resistant (MDR) E. coli and K. pneumoniae were d...

background: extended spectrum beta lactamases (esbls) are an important cause of transferable multidrug resistance (mdr) in gram-negative bacteria. the most described esbl genes are generally found within integron-like structures as mobile genetic elements. the aim of this study was to identify the accompanying of class 1 integrons and esbls in the mdr e. coli isolates. methods: susceptibility t...
