Introduction: Uropathogenic Escherichia coli (UPEC) is among the primary cause of urinary tract infections (UTIs). This study was conducted to determine the antibiotic resistance pattern of E. coli isolates from UTIs in Kermanshah. Methods: In this study, 180 midstream urine samples were collected from outpatients for five months. Based on differential biochemical tests such as oxidase, Indole,...

Background: Avian pathogenic Escherichia coli (APEC), which is the causative agent of colibacillosis, harbors several putative virulence genes. An important trait of APEC for both poultry and public health is antibiotic resistance. Objectives: In the present study, some potential virulence genes of APECs isolated from Northeast of Iran and their resistance to the quinolones antibiotics were stu...

Escherichia coli is an indicator in the quality control of pharmaceutical and other samples. Reduced graphene oxide (rGO) as a kind of carbon compositions was immobilized on glassy carbon electrode (GCE). Chronoamperometric and reduction methods were used for Au NPs decoration and it completed with polyclonal E. coli antibody and 0.5 W/V% Bovine Serum Albumin solution. Morphology and structure ...

BACKGROUND: Avian Colibacillosis can lead to important economic losses in the poultry industry. Escherichia coli the causative agent of this disease has acquired resistance to different antibiotics, including tetracycline. OBJECTIVES: This study was carried out to detect the distribution of tetracycline Group І efflux genes genes among E.coli isolates from from avian colibacillosis in Iran by P...

Background: Electron beam irradiation is one of the effective ways to control food-borne pathogens. We evaluated the effect of electron beam irradiation on survival of Escherichia coli O157:H7 and Salmonella enterica serovar Thyphimurium in minced camel meat during refrigerated storage. Methods: The meat samples were inoculated with E. coli O157:H7 and S. enterica serovar Thyphimurium and then...

Background and Aims: Q59L mutant of L-asparaginase enzyme from Escherichia coli (E. coli) has been introduced with lower side effects. This version of the enzyme might have potential applications in the treatment of leukemia patients. We utilized SHuffle T7 strain of E. coli, to produce the mutant enzyme in the presence of chaperone molecules. Materials and Methods: Q59LAsp gene was cloned in...

Background: Escherichia coli is one of the most important pathogens which could be transmitted by milk. The main aim of the present study was to assess risk factors related to the occurrence of E. coli in fluid milk marketed in Chittagong, Bangladesh. Methods: Totally, 169 milk samples were collected from different entry points in Chittagong, Bangladesh; and also, 17 samples were directly coll...

Background: Food borne pathogens are of the main concerns of food producers and consumers and Escherichia coli and Staphylococcus aureus create a lot of problems worldwide. The aim of this study was to evaluate antibacterial effects of monolaurin, sorbic acid and potassium sorbate on S. aureus and E. coli at different pH values and NaCl concentrations. Methods: Micro-well dilution assay was us...
