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...

this study was intended to investigate the effectiveness of static magnetic field on the growth of escherichia coli (e. coli) provided from two sources, the urine samples of patients with urinary tract infections and the reference strain e. coli atcc 25922. bacterial samples in nutrient broth were subjected to a range of magnetic intensities (2, 4, 6, 9, 14, 16, 18, and 20 mt) at various exposu...

with the aim of the secretion of human granulocyte macrophage-colony stimulating factor (hgm-csf) in escherichia coli, hgm-csf cdna was fused in-frame next to the signal sequence of st toxin (st-i) of exteroxigenic e. coli, containing 53 or 19 amino acids of signal peptide. the fused stsig::hgm-csf coding fragments were inserted into a t7-based expression plasmid. the recombinant plasmids were ...

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...

background and objective: escherichia coli o157:h7, an emerging pathogen, causes severe enteritis and the extraintestinal complication of hemolytic-uremic syndrome. the goal of this study was to evaluate the conjugate of e. coli o157: h7 lipopolysaccharide (lps) with diphtheria toxoid (dt) as a candidate vaccine in mice model. material and methods: lps from e. coli o157:h7 was extracted by hot ...

conclusions tetracycline resistance is widespread among uropathogenic e. coli isolates from human infections. moreover, the distribution of tetracycline resistance determinants among the studied e. coli was very similar to the findings of the international sourced gallery of clinical e. coli strains. background uropathogenic escherichia coli is one of the most prevalent infectious agents in hum...

conclusions the high prevalence of quinolone resistance genes, which indicates antibiotic resistance, in the imam reza hospital of mashhad is a major concern. hence, the antibiotics prescription policy should be revised, and infection control measures should be improved. results eighty-six (43%) isolates were ciprofloxacin-resistant. the pct identified 85 (42.5%) of 200 e. coli isolates as esbl...

Escherichia coli, originally called “Bacterium coli commune,” was first isolated from the feces of a child in 1885 by the Austrian pediatrician Theodor Escherich (Escherich, 1885). Escherichia coli is a common inhabitant of the gastrointestinal tract of humans and animals. There are E. coli strains that are harmless commensals of the intestinal tract and others that are major pathogens of human...
