The amino acid-producing organism Corynebacterium glutamicum cannot utilize glycerol, a stoichiometric by-product of biodiesel production. By heterologous expression of Escherichia coli glycerol utilization genes, C. glutamicum was engineered to grow on glycerol. While expression of the E. coli genes for glycerol kinase (glpK) and glycerol 3-phosphate dehydrogenase (glpD) was sufficient for gro...

OBJECTIVES The presence of ESBL/AmpC-producing E. coli in cattle has been reported previously, however information on veal calves is limited. This study describes the prevalence and molecular characteristics of E. coli with non-wild type susceptibility to cefotaxime in veal calves at slaughter. METHODS Faecal samples from 100 herds, 10 individual animals per herd, were screened for E. coli wi...

Verotoxigenic Escherichia coli infections in humans cause disease ranging from uncomplicated intestinal illnesses to bloody diarrhea and systemic sequelae, such as hemolytic uremic syndrome (HUS). Previous research indicated that pigeons may be a reservoir for a population of verotoxigenic E. coli producing the VT2f variant. We used whole-genome sequencing to characterize a set of VT2f-producin...

OBJECTIVE This study aimed to determine the prevalence and assess antimicrobial susceptibility of extended- spectrum β-lactamase-producing Escherichia coli isolated from clinical specimens of patients at hospitals in Khartoum State, Sudan. METHODS During April to August 2011, a total of 232 E. coli isolates were collected from various clinical specimens of patients. Isolates were identified, ...

A population-based study was performed to investigate the efficacy of mecillinam treatment of community-acquired urinary tract infections (CA-UTI) caused by extended-spectrum β-lactamase (ESBL) producing Escherichia coli. The study was conducted in South-Eastern Norway. Data from patients with CA-UTI caused by ESBL-producing and non-producing (random controls) E. coli were collected through int...

Escherichia coli (E. coli) is a widely distributed microorganism in nature and normally colonize the human gastrointestinal tract. E. coli strains are part of the normal gut microbiota. In recent years, some E. coli strains producing the genotoxin colibactin have been associated with development and progression of colon cancer. However, the role of E. coli and their toxins in carcinogenesis is ...

This study has evaluated the use of a commercially available Rainbow agar O157 and polymerase chain reaction (PCR) assays for the detection of Shiga-like toxin producing Escherichia coli and to serotype E. coli O157:H7 from raw meat. The Rainbow agar O157 was found to be selective and sensitive for the screening of the E. coli O157 from artificially and naturally contaminated meat samples. Shig...

In this study, drug resistance of 28 ESBL-producing Escherichia coli isolates obtained from 144 patients hospitalized at the Yüzüncüyil University Hospital at Van (YUH), Turkey, between 2009 and 2012 were characterized by pulsed field gel electrophoresis and antibiotic susceptibility tests. Antibiotic resistance profile was determined by Phoenix automated system (BD, USA). The ratio of ESBL-pro...
