The characterization of AmpC-type beta-lactamases was performed in a collection of 32 clinical Pseudomonas aeruginosa isolates with intermediate susceptibility or resistance to imipenem and ceftazidime. Twenty-one out of those 32 isolates overexpressed AmpC beta-lactamase, and the MICs of ceftazidime and imipenem were reduced after cloxacillin addition. Cloning and sequencing identified 10 AmpC...
The efficacy of treatment with a combination of ampicillin, imipenem, and vancomycin was compared with that of two-drug combinations or monotherapy in a model of experimental endocarditis using a strain of Enterococcus faecium with high-level resistance to vancomycin and moderate intrinsic resistance to ampicillin and imipenem. In vitro time-kill synergy studies demonstrated bactericidal synerg...
BACKGROUND This study investigates the effects of the antimicrobial cationic peptide omiganan-alone and combined with the antibiotic imipenem-on colonic anastomosis healing in presence of intraperitoneal sepsis induced in a rodent model of cecal ligation and puncture (CLP). METHODS Forty male Wistar rats were divided into 5 groups of 8 animals. Group 1 (control group) underwent laparotomy and...
BACKGROUND Conflicting evidence has been reported on the impact of ertapenem use on the susceptibility of Pseudomonas spp. to group 2 carbapenems. No extensive data for Acinetobacter baumannii are currently available. METHODS A retrospective time-series segmented regression analysis was conducted in a tertiary centre from January 2001 to December 2011. Ertapenem was introduced in January 2005...
BACKGROUND & OBJECTIVE Metallo beta-lactamase (MBL)-mediated resistance to carbapenems is an emerging threat in hospital isolates of Pseudomonas aeruginosa. Though there are several screening methods to detect this enzyme production, the National Committee for Clinical Laboratory Standards (NCCLS) does not have performance standards documented so far. There is not enough information from the In...
BACKGROUND AND OBJECTIVES Pseudomonas aeruginosa is one of the most important causative agents of nosocomial infections especially in ICU and burn units. P. aeruginosa infections are normally difficult to eradicate due to acquired resistance to many antibiotics. Recent appearance of carbapenem resistant P. aeruginosa isolates is considered a major healthcare problem. The present study was condu...
OBJECTIVES To study the effect of moxifloxacin versus imipenem/cilastatin (hereafter referred to as imipenem) treatment on the mortality of mice infected intravenously with different strains of Bacteroides fragilis and Escherichia coli. METHODS Groups of 20 mice each were infected intravenously with different strains of B. fragilis [moxifloxacin and imipenem susceptible or resistant, and ente...
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....
drug utilization evaluation (due) studies are designed to assess drug usage appropriateness. we aim to evaluate the drug utilization of intravenous ciprofloxacin and imipenem, two of the broad spectrum antibiotics that consume a significant proportion of our hospitals’ outlay, in different wards of a teaching hospital in zabol. during a 5 months period (december 2010 to may 2011), 263 patients ...
background: resistant strains of pseudomonas aeruginosa to imipenem was medical treatment problem, especiallyin burnt units of hospitals. objectives: this study was conducted to evaluate the antimicrobial effect of fe2o3 nanoparticles alone and functionalized with imipenem on p. aeruginosa starins producing metallo b-lactamases (mbl).materials and methods: a disk diffusion method was used to is...
