conclusions the remarkable rates of biofilm production ability among clinically isolated staphylococci emphasize the necessity of more effective infections control policies to prevent biofilm formation on medical devices and hospital environmental surfaces. background biofilm formation capacity is recognized as an important virulence factor in staphylococci that makes the organisms more resista...
background and objectives : the rapid emergence and dissemination of carbapenemase-producing klebsiella pneumoniae strains and other members of the enterobacteriaceae poses a considerable threat to the care of hospitalized patients and to public health. the aim of this study was to determine the frequency of metallo-β-lactamases (mbl) and vim-1 gene in multidrug-resistant strains of k. pneumoni...
abstract chickpea is weak in competition of weeds that damages to it at between 40 t0 60 percent. kermanshah province is one of the most important region for chickpea fields in iran. for these reosons, weed management is necessary in this crop. in order to evaluate of herbicides and stubble control on broad leave weeds control in chickpea. experiment was conducted in agricultural research stat...
Background & Aim: Important challenge for treatment of urinary tract infections is the spread of extended-spectrum beta-lactamases (ESBLs) producing Escherichia coli. Therefore, the frequencies of main beta-lactamase genes, resistance to beta-lactams and the ability of ESBLs production in urinary and fecal Escherichia coli of women with urinary tract infections were compared. Methods: In 60 Es...
conclusions the β-lactamase disk test is appropriately sensitive to detect esbls in mdr isolates of e. coli. background most urinary tract infections (utis) are caused by escherichia coli (e. coli) species. due to infections outbreaks of e. coli strains with multiple mechanisms of resistance to β-lactam antibiotics, the sensitivity of confirmatory tests to detect the extended spectrum β-lactama...
Introduction: Extended spectrum beta-lactamase (ESBL) producing Escherichia coli generate a major problem for clinical therapeutics and epidemiological study. The incidence of ESBL producing strains among clinical isolates has been steadily increasing during the past few years, and remains an important cause of failure of therapy with cephalosporins. The aim of this study was to determine the a...
chapter two presents three m-admissible function algebras ab, bd, and sl, to construct the universal abelian, band, and semilattice compactifications, respectively. the main results are (11.3), (12.3), and (12.4). some inclusion relationships between these function algebras and the other well-known ones, presented in section 8, are made via the devico of compactifications. chpter three is about...
introduction acetic acid bacteria are large group of obligate aerobic gram negative bacteria with the ability to oxidize ethanol to acetic acid (1). they are widely distributed in natural habitats and classified in family acetobacteraceae. members of this family are useful in industrial production of vinegar(2). acetic acid bacteria (aab) can use substrates as glucose, ethanol, lactate or glyc...
Background & Aims: The production of extended-spectrum-β-lactamases (ESBLs) is the main mechanism of resistance to β-lactam antibiotics. The outbreak of isolates simultaneously possessing several resistance mechanisms to β-lactam antibiotics caused a decrease in sensitivity of the confirmatory tests for ESBL. The aim of this study was the evaluation of the β-lactamase disk test method in the de...
