اسهال به عنوان یک اختلال گوارشی و از عوامل رایج در مرگ و میر کودکان کشورهای در حال توسعه می باشد. در میان پاتوژن های باکتریایی اشرشیا کلی مولد اسهال (dec) یکی از مهم ترین عوامل اسهال اندمیک و اپیدمیک در سطح جهان است. هدف از تحقیق حاضر، تشخیص مولکولی گروه های اشرشیا کلی مولد اسهال در کودکان به روش multiplex pcr و ارزیابی حضور اشرشیا کلی o157:h7 در نمونه ها است. روش کار: در سال 1393 (اردیبهشت تا ...
This study was designed to compare the efficacy of a phytobiotic containing a mixture of essential oils of Oreganum aetheroleum and an antibiotic containing ciprofloxacin as an active principle for the treatment of experimental Escherichia coli (E. coli) infection in broiler chickens. Two-hundred-day-old broiler chickens were divided into 5 equal groups. The 1st group was neither challenged nor...
Abstract Background and Objective: CTX-M type extended spectrum beta-lactamases is a rapidly expanding group of enzymes encountered with increasing frequency, especially, in Escherichia coli (E. coli). There are a few reports on phylogenetic background of E. coli isolates from clinical sources of under five-year- old children in Iran. The purpose of this study was phylotyping of E. coli isola...
Enterohemorrhagic Escherichia coli (EHEC), such as E. coli O157:H7, are emerging food-borne pathogens worldwide. This micro-organism can damage the epithelial tissue of the large intestine. The cytotoxic effects can be neutralized by probiotics such as Bifidobacterium bifidum. Probiotics are viable cells that have beneficial effects on the health of the host. The preventing activity of B. bifid...
Shiga toxin producing Escherichia coli have been associated with HUS, HC and TTP in human. We found recto-anal mucosal sample in sheep as well in cattle is the main site for E. coli O157 localization. 1246 E. coli isolates from 872 both healthy and diarrheic animals were analyzed, by screening for the presence of Shiga toxin-producing (VT 1 and VT 2) and intimin (eae) genes used Multiplex PCR. ...
Bacterial co-infections can probably influence the pathogenicity of H9N2 low pathogenic avian influenza virus (AIV). This study aimed to evaluate the effect of exposure time to Escherichia coli (O:2) on the pathogenicity of H9N2 AIV in broiler chickens. Three hundred and sixty broiler chickens were randomly allocated to six equal groups. At the age of 26 days, all chicks except groups 5 and 6 w...
Background and Objective: Urinary tract infection (UTI) is one of the most prevalent bacterial infections and Escherichia coli is the most common cause of it. The aim of this study was determination of the antibiotic resistance of E. coli isolated from urine of adult patients (≥15 years old) harboring UTI symptoms at Pars General Hospital in Tehran, Iran, for evaluating the most effective drug ...
Escherichia coli (E. coli) bacteria can damage DNA of the gut lining cells and may encourage the development of colon cancer according to recent reports. Genetic switches are specific sequence motifs and many of them are drug targets. It is interesting to know motifs and their location in sequences. At the present study, Gibbs sampler algorithm was used in order to predict and find functional m...
Background & Objective: Escherichia coli (E. coli) is considered to be the most common cause of urinary tract infections (UTIs) worldwide. Due to the recent rise in bacterial resistance to antibiotics and the appearance of multidrug-resistant E. coli, treatment options have been significantly limited, thus increasing the cost of treatment as well as morbidity and mortality rates, especially in ...
خلاصه مقدمه: غیرفعالسازی فتودینامیکی یکی از راهکارهای مقابله با پاتوژنهای مقاوم به دارو است. در این روش از یک رنگ حساسگر نوری غیر سمی استفاده میشود که بر روی سلولهای میکروبی قرار میگیرد و با طول موج خاصی از نور مرئی فعال میشود. هدف اصلی این مطالعه بررسی اثرغیرفعال سازی فتودینامیکی escherichia coli (atcc 25922) و سوی ه بالینی escherichia coli مقاوم به دارو با دو رنگ متیلن بلو وتولوئیدین ...
