OBJECTIVES The aim of the present study was to determine the prevalence and to characterize extended-spectrum β-lactamases- and/or carbapenemases-producing Enterobacteriaceae among Enterobacteriaceae isolated from retail chicken meat in Zagazig, Egypt. METHODS One hundred and six Enterobacteriaceae isolates were collected from retail chicken meat samples purchased in Zagazig, Egypt in 2013. S...
Sir, The worldwide emergence of carbapenemases is a major health issue leaving clinicians with few treatment options. Implementation of infection prevention and control (IPC) procedures relies on early detection of carbapenemase producers and distinction from other carbapenem resistance mechanisms. Various carbapenem hydrolysis methods allow detection of carbapenemase activity but do not differ...
The rapid spread of gram-negative bacteria resistance to carbapenems due the production carbapenemases requires new treatment options. activity carbapenem antibiotic biapenem, recently registered in Russia, against producers various was studied comparison with other antibiotics this group. Among NDM-type carbapenemase producers, 77.8% demonstrated clinical susceptibility biapenem; 50.3% and 21....
Background: This study aimed to investigate the distribution pattern of carbapenemases and evaluate their solitary contribution carbapenem resistance.
Enterobacteriaceae producing class D OXA-48 and OXA-48-like carbapenemases are an increasing concern. Detection is a diagnostic challenge because (i) some isolates are carbapenem susceptible and may go unrecognized, (ii) tests that detect carbapenem hydrolysis may be insensitive due to the relatively weak hydrolytic activity of these enzymes, (iii) the enzymes are not significantly inhibited by...
The study emphasizes the reasons use of beta-lactamase inhibitors in combination with beta-lactam antibiotics. ß-lactam-ß-lactamase inhibitors are currently the most successful strategy for infections caused by extended-spectrum β-lactamase and carbapenemases bacteria.
the nosocomial infections, caused by multi-drug resistant bacteria, are the most important cause of mortality throughout the world. one important mechanism against beta-lactam antibiotics is the production of beta-lactamases. enterobacteriaceae and non-fermentative bacteria, like pseudomonas aeruginosa and acinetobacter baumannnii may produce these enzymes. currently, there is no vaccine to pre...
Ertapenem is a carbapenem that shares the activity of imipenem and meropenem against most species, but is less active against non-fermenters. Activity is retained against most strains with AmpC and extended-spectrum beta-lactamases, although resistance can arise if these enzymes are combined with extreme impermeability. Resistance can also be caused by IMP, VIM, KPC and NMC carbapenemases, but ...
background and objectives: klebsiella pneumoniae is an opportunistic pathogen responsible for up to 10% of nosocomial infections. the emergence and spread of multidrug resistant k. pneumoniae , mostly due to the production of extended-spec- trum β-lactamases (esbl) and carbapenemases, is often responsible for antibiotic treatment failure of these infections. we compared the antibiotic resistanc...
