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...

Objective(s): Escherichia coli strains are common pathogens that can cause urinary tract infections (UTI). This study aimed to assess E. coli phylogroups and virulence types in male and female UTI patients.Materials and Methods: In the present study, 160 uropathogenic E. coli (UPEC) isolates (from both sexes) were assigned to phylogroups/types and some extraintestinal virulence factors were det...

helicobacter pylori infection is among the most prevalent infections in the world involving more than half the adult population. h. pylori infection results in active chronic gastritis, peptic ulcers and enhances the risk of gastric malignancies. it is of utmost importance to prevent h. pylori infection particularly in highly prevalent countries including iran. the urease holoenzyme produced by...

background :    unfortunately, antibiotic resistance has become an increasingly critical problem in many countries like iran. since there are very few published data on antibiotics resistance in alborz province, the aim of this study was to survey the pattern of antimicrobial resistance and prevalence detection of tem-type beta-lactamases among clinical isolates of escherichia coli using univer...

The behaviour of Escherichia coli O157:H7 was studied during the manufacture and storage of Iranian white cheese in brine. Cheese was manufactured using pasteurized cow milk and inoculated with E. coli O157:H7 with inoculum level of 103 cfu/ml. Four treatments were designed. Cheeses were made with or without starter culture and kept immersed in 6 or 8% salt brine during ripening and storage. Ch...

We establish an identity for compact hyperbolic surfaces with or without boundary whose terms depend on the dilogarithms of the lengths of simple closed geodesics in all 3-holed spheres and 1-holed tori in the surface.
