Group 1 capsules of Escherichia coli are similar to the capsules produced by strains of Klebsiella spp. in terms of structure, genetics, and patterns of expression. The striking similarities between the capsules of these organisms prompted a more detailed investigation of the cps loci encoding group 1 capsule synthesis. Six strains of K. pneumoniae and 12 strains of E. coli were examined. PCR a...

The Australian Group on Antimicrobial Resistance performs regular period-prevalence studies to monitor changes in antimicrobial resistance in selected enteric Gram-negative pathogens. The 2011 survey focussed on hospital-onset infections, examining isolates from all specimens presumed to be causing disease. In 2011, 1,827 Escherichia coli, 537 Klebsiella species and 269 Enterobacter species wer...

Background and Aims: Klebsiella pneumoniae is a gram negative opportunistic pathogen of nosocomial infections that causes pneumonia, urinary tract infection (UTI), meningitis, septicemia and diarrhea. The emergence and spread of carbapenemase producing Klebsiella pneumoniae often cause failure in the treatment of infections. The aim of this study was to evaluate the prevalence of carbapenemase ...

INTRODUCTION Although independently acquired, plasmid-mediated quinolone resistance appears to be linked with extended-spectrum or AmpC-type beta-lactamases. Since no data are available in African countries, the prevalence of qnr genes at the University Hospital Ibn Rochd, Casablanca, Morocco, was investigated. METHODOLOGY Between October 2006 and March 2007, the following 39 randomly selecte...

A bacteriocin typing method was evaluated using 200 strains of Klebsiella aerogenes, 93% of which fell into 11 distinct types. The typing technique was successfully applied to the monitoring and control of hospital cross-infection.

The key objective of current study was to analyse the bacterial diversity canal water Lahore, Pakistan. Members Enterobacteriaceae were targeted that may pose serious health issues human health. Total 50 strains isolated by using Eosin Methylene Blue agar and MacConkey agar. 16S rRNA gene sequencing 30 confirmed final taxonomic status strains. results manifested belong genera Enterobacter, Esch...

Background and Objective: The production of carbapenemases especially Klebsiella pneumoniae carbapenemase (KPC) is the most important mechanism of enzymatic resistance in isolated Enterobacteriaceae such as K. pneumoniae. The purpose of this study was detected of the carbapenemase producer K. pneumoniae strains with phenotypic and genotypic ...

in a period of nine months, 225 strains of gram-negative bacilli isolated from burns were identified by a variety of tests in two burn centers in tehran. the most common species were pseudomonas aeruginosa, pseudomonas fluorescens, escherichia coli, enterobacter agglomerans, enterobacter cloacae and klebsiella pneumoniae. many strains of acinetobacter spp, providencia spp, proteus spp, serratia...

Antibiotic-associated hemorrhagic colitis (AAHC) is associated with Klebsiella oxytoca. This study analyzed whether cytotoxic properties are linked to specific subtypes of K. oxytoca. Klebsiella isolates from stools of AAHC patients, healthy carriers, and diarrhea patients as well as from infections of other organs were investigated. Cytotoxic effects on human epithelial cells were limited to t...
