background and objectives: there is a growing trend towards investigating natural products as sources of compounds with biological effects and many researches have been carried out in order to find effective medications against many diseases. cancer is no exception and studies focusing on evaluating the effects of different materials on dna, give valuable information in cancer researches and ca...
background and objectives: β-lactamase production is the predominant mechanism for resistance to β-lactams in enterobacteriaceae. the producing isolates are often multidrug resistant and are major hosts for extended spectrum β-lactamases. this study was designed to determine the prevalence of extended-spectrum β-lactamase producing isolates of escherichia coli and klebsiella pneumoniae and thei...
بررسی شیوع اینتگرون در اشرشیا کلی و کلبسیلا در کودکان مبتلا به عفونت دستگاه ادراری مقاوم به چند دارو
Abstract Background: The aim of this study was to identify multidrug resistant isolates of Escherichia coli and K. pneumoniae causing urinary tract infections (UTI) in children and the occurrence of class 1, 2 and 3 integrons in the antibiotic resistant isolates.. Methods: A total of 200 urine samples were processed. Urine culture was done using conventional microbiological techniques. Bioc...
Background: This study aimed to describe the association between age groups and antimicrobial susceptibility patterns, also integron presence in Escherichia coli and Klebsiella pneumoniae isolates from Tabriz, Iran. Materials and methods: 140 isolates of E. coli and 150 isolates of K. pneumoniae, both comprising the same number of children and adult isolates were examined for susceptibil...
Background and purpose: Increasing resistance to Quinolones in Escherichia coli and Klebsiella pneumonia in Sari, has caused many problems in treatment. Mutation in gyrA gene lead to changes in amino acids and resistance against Fluoroquinolones in E. coli and K. pneumonia. This study aimed at identifying remarkable mutations in E. coli and K. pneumonia isolates using PCR-SSCP analysis. Materi...
