A 76-year-old woman had recurrent urosepsis due to extended-spectrum beta -lactamase-positive Escherichia coli. Imipenem resistance was detected after long-term imipenem-meropenem therapy. The carbapenem-hydrolyzing enzyme gene was identified as blaKPC-3. To our knowledge, this is the first documented case in which carbapenem-resistant E. coli emerged during therapy with imipenem and meropenem,...
Using time-kill methodology, we investigated the interactions of fosfomycin with meropenem or colistin or gentamicin against 17 genetically distinct Klebsiella pneumoniae clinical isolates carrying blaKPC-2. Synergy was observed with meropenem or colistin against 64.7 and 11.8% of tested isolates, while the combination with gentamicin resulted in indifference. All studied combinations showed im...
We present two case reports of drug interaction between valproic acid and meropenem. In comparison with expected population-kinetic based serum levels, we observed 90.8 and 93.5% decrease in valproic acid serum levels during concomitant administration with meropenem. If carbapenems need to be administered to valproic acid treated patient, other anticonvulsant addition seems to be the appropriat...
BO-2727, a new 1-beta-methyl-carbapenem, was active at concentrations of 6.25 micrograms/ml or less against gram-positive and gram-negative bacteria, including some imipenem- and/or meropenem-resistant (MICs, > or = 12.5 micrograms/ml) Pseudomonas aeruginosa strains, against which it proved generally fourfold more active than imipenem and meropenem. BO-2727's antipseudomonal activity and its br...
Although beta-lactam antibiotics are not considered as antituberculous drugs, it has been recently shown that the combination of carbapenems and clavulanate is bactericidal in vitro. We evaluated in a murine model of tuberculosis the activity of carbapenems alone and combined with clavulanate against Mycobacterium tuberculosis. Swiss mice infected intravenously with 3 x 10⁵ M. tuberculosis H37R...
Sphingomonas paucimobilis is a nonfermentative gram-negative bacillus of low pathogenicity. The organism has been involved in causing a wide range of infections in community and hospital settings. Only 3 cases of meningitis caused by this organism have been reported so far. We report a rare case of S paucimobilis meningitis who presented with atypical symptoms. A 50-year-old female presented wi...
This study aims in identifying MBLs particularly Zn requiring Molecular Class B enzymes produced by Pseudomonas aeruginosa and Acinetobacter baumannii .The resistance by these organisms are in a rise against all antibiotics including carbapenems and no prescribed CLSI guidelines is available for detecting them. Clinical isolates antibiotic susceptibility was determined by number of phenotypic t...
The concentrations of meropenem were measured in plasma, bronchoalveolar lavage (BAL) and epithelial lining fluid (ELF) 0.5-8 h after the administration of a single 1 g iv dose of meropenem. Thirty-five patients undergoing bronchoscopy were studied. Mean concentrations in plasma, BAL and ELF, respectively, measured by high performance liquid chromatography, were as follows: 0.5 h: 25. 96, 0.14,...
The influence of meropenem, a new carbapenem antibiotic, on cell morphology and in-vitro lipopolysaccharide (LPS) release from Escherichia coli was compared with that of imipenem, ceftazidime, tobramycin and ciprofloxacin. Free and cell-associated LPS was quantified by means of a capture ELISA method based on the recognition of E. coli LPS by monoclonal antibodies. Microscopically, meropenem wa...
OBJECTIVES The activity of BAL30072 was compared with that of anti-Acinetobacter reference drugs against meropenem-non-susceptible Acinetobacter baumannii isolates associated with up-regulation of the intrinsic OXA-51-like enzyme or an acquired OXA. METHODS Antimicrobial susceptibility testing was investigated by broth microdilution of 310 non-duplicate, meropenem-non-susceptible A. baumannii...
