Carbapenem-resistant Enterobacteriacea (CRE) has become a growing food safety issue and an ongoing public-health problem of global dimensions. This research study determined the presence CRE in fresh vegetables. Vegetables were purchased from retailers analyzed for Enterobacteriaceae line with Standard guidelines. The antibiotic profile isolated was using Antibiotic Susceptibility Test (AST). M...

All (236) Pseudomonas aeruginosa isolates resistant to imipenem and/or meropenem collected during a multicenter (127-hospital) study in Spain were analyzed. Carbapenem-resistant isolates were found to be more frequently resistant to all beta-lactams and non-beta-lactam antibiotics than carbapenem-susceptible isolates (P < 0.001), and up to 46% of the carbapenem-resistant isolates met the criter...

Introduction: Regarding the crucial role of geographic factors in different mechanisms underlying bacterial antibiotic resistance worldwide, it is necessary to design and conduct studies determine prevalence specific this phenomenon. Objectives: This study was performed assess carbapenem-resistant gram-negative bacilli which produce carbapenemase, Loghman Hakim hospital, Tehran. Patients Method...

objectives the objective of this study was to develop the primers for single and/or multiplex pcr amplification assays for simultaneous identification of class a, class b, and class d carbapenem hydrolyzing β-lactamases in enterobacteriaceae and then to evaluate their efficiency. conclusions we have reported here a reliable method, composed of single and multiplex pcr assays, for screening all ...

Carbapenem-resistant Pseudomonas aeruginosa, Acinetobacter spp., and Enterobacteriaceae pose urgent public health threats. The differential burden, relative risks, associations with antimicrobial consumption, and temporal trends of those taxa in large, geographically diverse U.S. health systems remain under reported. Electronic records of all patients in a geographically dispersed 280-hospital ...

The oxacillinase gene was reported to confer limited resistance to carbapenem in Acinetobacter baumannii. In this study, we have demonstrated that an A. baumannii clinical isolate harboring a plasmid, pTVICU53, has 11,037 bp encoding 13 open reading frames. A bla(OXA-58) gene with an upstream insertion of truncated ISAba3 (DeltaISAba3) and IS1008 was found in this plasmid. DeltaISAba3and IS1008...

BACKGROUND AND PURPOSE To detect and characterize class 1 integrons among carbapenem-resistant strains of Acinetobacter spp. at University Malaya Medical Centre (UMMC), Kuala Lumpur, Malaysia. METHODS Thirty nine carbapenem-resistant Acinetobacter strains were obtained from UMMC from August 2003 to March 2004 and analyzed for the presence of bla(IMP) genes and class 1 integrons. RESULTS Cla...

Carbapenem resistance among Enterobacteriaceae is an emerging problem worldwide. Klebsiella pneumoniae carbapenemase (bla(KPC)) enzymes are among the most common beta-lactamases described. In this study, we report the development and validation of a real-time PCR (q-PCR) assay for the detection of bla(KPC) genes using TaqMan chemistry. The q-PCR amplification of bla(KPC) DNA was linear over 7 l...

BACKGROUND In order to study the enzymatic carbapenem resistance mechanisms in Acinetobacter baumannii isolates from Argentina, we performed molecular characterization on 41 epidemiologically unrelated strains isolated from 1995 to 2006 with diminished susceptibilities to imipenem and meropenem. METHODOLOGY Acinetobacter baumannii isolates were identified with the ARDRA technique. The total g...

In the last few years, phenotypically carbapenem resistant Acinetobacter strains have been identified throughout the world, including in many of the hospitals and intensive care units (ICUs) of Australia. Genotyping of Australian ICU outbreak-associated isolates by pulsed-field gel electrophoresis of whole genomic DNA indicated that different strains were cocirculating within one hospital. The ...
