Introduction: Acinetobacter baumannii is an important bacteria because of high ability to obtain antibiotic resistance genes and creation of multi-drug resistant strains (MDR). Today, the active efflux pumps has been suggested as one of the most important mechanisms of intrinsic and acquired resistance of antibiotics in bacteria. The aim of this study was Evaluation of phenotypic and genotypic ...
conclusions considering the high prevalence of esbl genes (bla ctx-m, 87%; and bla tem, 82%), fluoroquinolones may be used as an alternative drug in treatment, although resistance to this family is increasing as well. as a result, this increasing trend should be prevented using appropriate guidelines for prescription. background escherichia coli is the most important as well as the most common ...
Klebsiella pneumonia is a gram negative bacillus of which it's resistant strains are a common source of nosocomial infections . The goal of this study is determination of drug sensitivity of these resistant strains, and study of causes involved in the resistant especially the presence of plasmid. Ten different strains of klebsiella pneumoniae were isolated from clinical specimens collected from...
Background and purpose: Acinetobacter has emerged as a significant opportunistic pathogen responsible for nosocomial infections. Treatment of infections due to this organism is becoming a serious clinical concern and this bacterium is frequently resistant to multiple classes of antibiotics such as family of β-lactam drugs. β-lactamases enzyme represent the main mechanism of bacterial resista...
Background & Aims: The increasing rate of antibiotic resistant bacteria in different wards of hospitals, especially in the intensive care units and increasing rates of morbidity and mortality due to these bacteria, highlights the need for awareness of antibiotic resistance patterns. The aim of this study was to determine the antibiotic resistance patterns of microorganisms isolate...
the present study aimed to evaluate the antibiotic resistance pattern of escherichia coli strains isolatedfrom animals to ascertain the levels of antibiotic resistance pervasiveness. a total of 28 e. coli strains wereisolated from faecal samples and the antibiotic resistance pattern of e. coli strains was determined by meansof disc diffusion assay. the resistance pattern determined for all stra...
conclusions our data showed that, the high prevalence of beta-lactamase genes among isolates, and it. our findings may provide useful insights in replace of the appropriate antibiotics and it may also prevents of esbls, mediated resistance problem. results from 145 strains of e. coli, 51(35.2%) and 61(42.1%) isolates were resistance to ceftazidime and cefotaxime, respectively. esbl production w...
Background: Increasing resistance of Pseudomonas aeruginosa to ciprofloxacin in ICU/burn units has created a problem in the treatment of infections caused by this microorganism. Methods: Fifty P. aeruginosa strains were isolated from burn patients hospitalized in the Kerman Hospital during May 1999-April 2000 and were tested for in-vitro sensitivity to different antibiotics by disc diffusion br...
