conclusions anova results showed that the effect of cycle and time on the selected bacterial removal efficiency were more important than that of the microbial concentration. results the results showed that e. coli and e. faecalis were effectively treated at 10 pulse/s in 9 minutes and 6 log cfu/ml bacterial suspension (p < 0.0001 for e. coli with 99.99% (4 log) and p = 0.0002 for e. faecalis wi...
Background and Objective: Escherichia coli (E-coli) is a normal gram negative organism that inhabit the human and animal intestinal tract. Pap G gene has an important role in creating P -fimbriae tip and in producing septicemia and urinary tract infection. The aim of this study was to investigate the presence of pap G gene in EPEC strains isolated from urine and blood. Materials and Metho...
زمینه مطالعه: فیمبریه باکتری F5 ( K99) E. coli مهمترین و شایعترین عامل چسبنده‌ای که تاکنون برروی سویه‌های اشریشیاکلی درگیر در اسهال گوساله‌هاشناخته شده است. این باکتری از طریق توکسین‌های مقاوم حرارتی (ST) سبب اسهال در گوساله‌های تازه متولد شده می‌شود. با افزایش نگرانی در مورد گسترش مقاومت‌های آنتی بیوتیکی، یافتن راه حل جایگزین مانند استفاده از کلی سین‌ها ضرورت دارد. کلی سین‌ها ترکیبات آنتی ب...
conclusions the alcoholic extract of p. harmala was very effective against the selected esbl-producing e. coli isolates harboring the tem gene. therefore, it could be suggested as an antibacterial agent in the future. more researches are necessary for detecting the mechanism of this plant’s behavior and its pharmacological effects. results results of this study showed that in disk diffusion met...
background extended-spectrum beta-lactamases (esbls) are a group of enzymes that hydrolyze antibiotics, including those containing new cephalosporins, and they are found in a significant percentage of escherichia coli and klebsiella pneumoniae strains. with the widespread use of antibiotics, difficulties with infection therapy caused by drug resistant organisms, especially those that have acqui...
the aim of this study was to assess the prevalence of esbl-producing e. coli in agricultural fields of gorgan district, golestan province. soil samples were collected from 20 agricultural fields, half of them treated with chemical fertilizers and the rest with bovine manure. two samples, from surface and a depth of 15cm, were taken. after enrichment and culture onto macconkey agar, pink colored...
escheric hia coli o157:h7 lives in the intestines of healthy cattle, and can contaminate meat during slaughtering pr actices . detection of the low infectious dosage of bacterium requires a sensitive method. we developed polymerase chain reaction (pcr) assays to detect the gene stx2 irrespective of the bacterial serotype. in this study, the detection limit of the pcr protocol in detecting stx2 ...
فعالیت ضد قارچی کیتیناز های ترشح شده از bacillus pumilus sg2 پس از کلون کردن در e. coli، خالص سازی با ستون نیکل و سنجش فعالیت کیتینازی، روی قارچ ها و باکتری های مهم بیماریزای گیاهی مورد ارزیابی قرار گرفت و اثرات بازدارندگی این کیتینازها اثبات شد.
Abstract Background and Objective: Escherichia coli is the most common cause of urinary tract infections in children and the leading cause of intra-abdominal infections (peritonitis and abscess) followed intestinal injuries. Urinary tract infection, including cystitis and pyelonephritis, is a common childhood infection. E. coli causes more than 90 percent of the community acquired and 50% of ho...
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...
