OBJECTIVES The impact of appropriate antimicrobial therapy and antimicrobial resistance on the outcome of bacteraemia due to Enterobacter spp. remains unclear. The aim of our study was to evaluate the effect of antimicrobial therapy in 377 consecutive episodes of Enterobacter bacteraemia. PATIENTS AND METHODS This includes retrospective analysis of a prospectively collected cohort. Clinical v...

OBJECTIVES To study the incidence, antimicrobial susceptibility pattern, age and sex distribution, mortality and prognostic factors in cases of Enterobacter bacteremia. METHODS A total of 18,745 indoor patients with suspected bacteremia were included in study. Enterobacter spp were identified and speciated using standard protocols. Antimicrobial susceptibility testing was done using Stoke's d...

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...

Gram negative bacteria are most commonly involved in causing Urinary tract infection (UTI), a urinary disease most commonly found in developing countries. The regular monitoring of specific areas gains the knowledge about the prevalence of these in the UTI and their susceptibility pattern is useful for the clinicians to choose correct empirical treatment. Therefore, the aim of this study was to...

Three new cephalosporins, ceftazidime, ceftizoxime, and cefotiam, were evaluated in vitro against clinical isolates, and their activities were compared with those of other cephalosporins, mezlocillin, and tobramycin. All three new cephalosporins were very active against gram-positive cocci (except enterococci), but mezlocillin was more active against Streptococcus ssp. Cefotiam and cefamandole ...

The Australian Group on Antimicrobial Resistance (AGAR) performs regular period-prevalence studies to monitor changes in antimicrobial resistance in selected enteric Gram-negative pathogens. The 2010 survey focussed on community-onset infections, examining isolates from urinary tract infections from patients presenting to outpatient clinics, emergency departments or to community practitioners. ...

There are 3 main groups of multiple resistant Gram-negative bacteria:  Enterobacteriaceae with ESBL or AmpC enzymes – Escherichia coli, Klebsiella spp., Enterobacter cloacae, Citrobacter freundii, Morganella morganii, Serratia marcescens  Acinetobacter spp. – resistant to aminoglycoside antibiotics as well as occasionally carbapenems and Colistin  Pseudomonas spp. – resistant to combinations...

The plasmid-encoded quinolone resistance gene qnrA confers low-level quinolone resistance, facilitating selection of higher-level resistance. Epidemiologic surveys for qnrA were extended to isolates of Enterobacter spp. and to quinolone-susceptible Enterobacteriaceae. Two (10%) of 20 ceftazidime-resistant quinolone-susceptible Klebsiella pneumoniae strains carried the gene, as did 12 (17%) of 7...

The antimicrobial activity of ethanol extract obtained from Rauvolfia tetraphylla was tested against bacterial species of Escherichia coli ATCC 69314, Streptococcus lactis NCIM 50038, Enterobacter aerogenes NCIM 2340, Alcaligenes faecalis ATCC 15246, Pseudomonas aeruginosa NCIM 2200, Proteus vulgaris ATCC 6380 and fungal species of Fusarium oxysporum NCIM 1008, Alternaria helianthii ATCC 201540...

Enterobacter spp. have been implicated as opportunistic pathogens which over the years have gained resistance toward most of the available therapeutic drugs. We sequenced two multidrug-resistant Enterobacter cloacae isolates harboring multiple efflux pump genes. These isolates exhibited strain-specific modulation of efflux pump protein expression.
