background and objectives: urinary tract infections (utis) are of the most common bacterial diseases worldwide. we investigate the antibiotic susceptibility patterns of escherichia coli (e. coli) strains isolated from pediatric patients with community acquired urinary tract infection (uti) to find a clinical guidance for choosing a right empirical antibiotic in these patients. materials and met...
abstract background: pseudomonas aeruginosa is one of the most common gram negative bacteria involved in nosocomial infections. presence of extended-spectrum beta-lactamases (esbls) genes, play an important role in induction of resistance in beta-lactamase producing species to beta lactam antibiotics. frequency of resistance to these antibiotics is increasing. in this study, antibiotic sensitiv...
With the occurrence of extended-spectrum beta-lactamases (ESBLs) in Pseudomonas aeruginosa being increasingly reported worldwide, there is a need for a reliable test to detect ESBLs in clinical isolates of P. aeruginosa. In our study, a total of 75 clinical isolates of P. aeruginosa were studied. Nitrocefin tests were performed to detect the beta-lactamase enzyme; isoelectric focusing electroph...
مقدمه: درسالهای اخیر شاهد گزارشات زیادی از پیدایش ایزوله های انتروباکتر مقاوم به آنتی بیوتیکهای بتالاکتام هستیم. بتالاکتامازهای وسیع الطیف (esbls) از مهمترین مکانیسمهای مقاومت به این داروها محسوب میشوند. هدف از این مطالعه تعیین شیوع esbls در ایزوله های مقاوم، به روش double disk approximation test (ddat) وتعیین فراوانی ژن blaper-1 است. مواد و روش ها: 100ایزوله انتروباکتر از بیماران بستری در بی...
Background and purpose: Citrobacter species can cause opportunistic hospital-acquired infections and their treatment has become problematic following the acquisition of extended spectrum beta- lactamases (ESBLs). The purpose of this study was to determine the frequency of ESBL genes in clinical isolates in Kermanshah Imam Reza Hospital. Materials and methods: In this study, 70 Citrobacter isol...
Carbapenemase-producing Enterobacteriaceae (CPE) are rapidly spreading worldwide. Early detection of fecal CPE carriers is essential for effective infection control. Here, we evaluated the performance of a meropenem combined disk test (CDT) for rapidly differentiating CPE isolates directly from rectal swabs. The screening method was applied for 189 rectal swabs from hospitalized patients at hig...
Background and Objective: Beta-lactamases are the most important factors in the resistance to beta-lactam antibiotics among gram-negative bacteria, especially Klebsiella pneumoniae. Nowadays, the prevalence of infections caused by extended-spectrum β-lactamases (ESBLs)-producing K. pneumoniae is increasing, as one of the emerging health problems throughout the world. This study aimed to investi...
Background: Antimicrobial resistance is a growing problem in many bacterial pathogens and is of particular concern for hospital-acquired nosocomial infections. Klebsiella pneumonia is an important cause of nosocomial infections has rapidly become the most common extended spectrum beta-lactamases (ESBLs) producing organism. ESBL are defined as the enzymes capable of hydrolyzing oxyimino-cephalos...
background : imipenem-resistant gram negative bacteria, resulting from metallo-beta-lactamase (mbls)-producing strains have been reported to be among the important causes of nosocomial infections and of serious therapeutic problem worldwide. because of their broad range, potent carbapenemase activity and resistance to inhibitors, these enzymes can confer resistance to almost all beta-lactams....
