Abstract Background and Objective: Klebsiella pneumoniae is one of the agents causing nosocomial infection therefore, we decided to report the prevalence of Klebsiella pneumoniae caused infection. Material and methods: The frequency of Klebsiella in culture media samples of Panje Azar hospital was studied in 2011-2012. After determination of the species with biochemical methods and determinatio...
Background and Aim: Klebsiella pneumoniae is a member of the Enterobacteriaceae family. There is a global emergence of multidrug-resistant (MDR) strains of K. pneumoniae, a Gram-negative enteric bacterium that causes nosocomial and urinary tract infections. The aims of the present study were to identify the Klebsiella pneumoniae infections in hospitalized patients, characterization of blaCTX ge...
Introduction: A Klebsiella pneumoniae bacterium, which is the most important species of the Klebsiella genus, mainly causes hospital infections. Moreover, it has a high resistance to most of the available antibiotics, which has caused concern among doctors all over the world. Therefore, the amount of antibiotic resistance and the effect of these antibiotics on Klebsiella pneumoniae isolates pr...
Klebsiella species is the second most commonly isolated gram-negative organism in sepsis and a frequent causative pathogen in pneumonia. The receptor for advanced glycation end products (RAGE) is expressed on different cell types and plays a key role in diverse inflammatory responses. We here aimed to investigate the role of RAGE in the host response to Klebsiella (K.) pneumoniae pneumonia and ...
In this study, we tested the abilities of the Vitek 2, BD Phoenix, and Kirby Bauer disk diffusion tests to detect carbapenemase production in a collection of 14 Klebsiella pneumoniae carbapenemase (KPC)-producing non-Klebsiella pneumoniae isolates. In addition, we evaluated 13 KPC-positive K. pneumoniae isolates by using each of these methods and applied both 2009 and 2010 CLSI carbapenem inter...
objective(s) different types of extended spectrum beta-lactamases (esbls) are encountered in the clinical settings worldwide. there are a few studies regarding the prevalence of esbl genes among klebsiella pneumoniae isolates at tehran especially those of blaper and blactx. the aim of this study was to determine the prevalence of blashv, blatem ,blaper and blactx genes among clinical k. pneumon...
background and aims: extended-spectrum β-lactamase (esbl) producing gram negative bacteria are resistant to penicillins, narrow and extended-spectrum cephalosporins, and aztreonam; also they are frequently resistant to trimethoprim-sulfamethoxazole, aminoglycosides, and quinolones. this study aimed to investigate the prevalence of plasmid-mediated quinolone resistance (pmqr) determinants qnra, ...
background and objectives: klebsiella pneumoniae ( k. pneumoniae ) is an opportunistic microorganism. this study aimed to investigate the presence of mag a gene and antimicrobial susceptibility in k. pneumoniae . materials and methods: 195 clinical specimens were collected from hospitals of shahrekord, iran. bacterial culture, biochemical diagnostic standard test, determination of antibiotic se...
background and aims: recently it has been proved that some of enterobacteriacea like klebsiella pneumoniae, which carry pks islands, damage dsdna by encoding colibactin genotoxin; and finally they induce some apoptosis in damaged mucosal cells. this study aimed to isolating the clbn and clbb genes, which are the markers of the pks genomic island, from pks cluster in these bacteria materials and...
b ackground: the prevalence of antibiotic resistance among extended spectrum β-lactamase (esbl) producing escherichia coli and klebsiella pneumoniae has been increased markedly in recent years. the present study was done to know the prevalence of esbl production among isolates of e. coli and k. pneumoniae and to study the susceptibility pattern of isolates against different antibio...
