Background & Aims: Imipenem is a member of Carbapenem with stability against most -lactamases .It is of particular use in the treatment of infections associated with drug resistant gram negative bacteria harboring ESBL and AmpC genes. The aim of this study was to determine the imipenem resistance in gram negative bacteria causing nosocomial infections and the presence of metallo--lactamases (MB...
background and objective: metallo-beta-lactamase (mbl)-mediated resistance is an emerging threat in hospital isolates of pseudomonas aeruginosa. there is not enough information from iran regarding the prevalence and the screening methods for such enzymes. the present study was undertaken to detect metallo betalactamase in strains of p. aeruginosa isolated from burned patientusingphenotypic meth...
background : pseudomonas aeruginosa is a severe challenge for antimicrobial therapy, because of chromosomal mutations or exhibition of intrinsic resistance to various antimicrobial agents such as most β-lactams. we undertook this study to evaluate the existence of sme, aim and vim metallo-beta lactamases encoding genes among p. aeruginosa strains isolated from icu patients in al-zahra hospit...
conclusions epidemiological and regional evaluation of mbl-producing p. aeruginosa through simple and inexpensive methods should be considered for effective treatment of carbapenem-resistant p. aeruginosa infections. results amongst all the p. aeruginosa isolates, 58.7% were resistant to imipenem while 31.8%, 13.5% and 74.4% were resistant to meropenem, doripenem and ertapenem, respectively. am...
NDM-1 (New Delhi metallo-?-lactamase 1) is an enzyme that is carried in certain gram negative
New Delhi metallo-β-lactamase 1 (NDM-1) is a novel type of metallo-β-lactamase (MBL). Enterobacteriaceae carrying this NDM-1 encoding gene, bla(NDM-1), have been identified worldwide. Bacteria carrying bla(NDM-1) are not only resistant to carbapenem, but also highly resistant to many classes of antibiotics, which indicate the importance of prompt identification of these bacteria and implementat...
A total of 10 metallo-β-lactamase-producing isolates of six different species, including Brevundimonas diminuta (n = 3), Rhizobium radiobacter (n = 2), Pseudomonas monteilii (n = 1), Pseudomonas aeruginosa (n = 2), Ochrobactrum anthropi (n = 1), and Enterobacter ludwigii (n = 1), were detected in the sewage water of a hospital. The presence of bla(VIM-13) associated with a Tn1721-class 1 integr...
This work reports, for the first time, the presence of New Delhi metallo-β-lactamase 1 (NDM-1) in Pseudomonas aeruginosa. Moreover, this is the first report of the NDM-1 presence in the Balkan region. Cosmid gene libraries of carbapenem-nonsusceptible Pseudomonas aeruginosa clinical isolates MMA83 and MMA533 were screened for the presence of metallo-β-lactamases. Accordingly, both MMA83 and MMA...
background: pseudomonas aeruginosa is the causing agent of many hospital infections and metallo-beta-lactamases (mbl) are being reported with increasing frequency. the aim of this study was to determine the frequency of metallo-&beta-lactamases; (mbl) and vim-1 gene in multidrug-resistant strains of p. aeruginosa isolates and to compare the methods of phenotypic and molecular detection. materia...
Electrochromic devices (ECDs) containing iron-based metallo-supramolecular polymers (Fe-MEPE) and Prussian blue (PB) as electrode materials, polymer electrolyte flexible ultra-thin ITO glass transparent conductive substrate are demonstrated.
