Identification of ACT-1 Plasmid-Mediated AmpC β-Lactamase Producing Citrobacter freundii from a Chinese Patient
Dear Sir, Enterobacteriaceae, other than Escherichia spp. and Klebsiella spp., can cause serious nosocomial infections and appear to have become increasingly drug resistant. Citrobacter freundii, belonging to the Enterobacteriaceae family, is a prominent opportunistic pathogen responsible for serious infections in immunocompromised individuals. C. freundii is characterized by the presence of ch...
متن کاملFirst Detection of VIM-4 Metallo-β-Lactamase-Producing Citrobacter freundii in China
Dear Sir, Carbapenems are one of the most critically important antimicrobials and are considered as last-choice drugs in clinical settings. However, the emergence and dissemination of Enterobacteriaceae carrying acquired metallo-β-lactamases (MBLs) is being increasingly reported throughout the world, presenting a serious threat to the effectiveness of carbapenem treatment [1]. Acquired MBLs, su...
متن کاملAmpC β lactamases in Urinary Klebsiella pneumoniae Isolates: First Report of ACC Type AmpC β-lactamase Resistance in Iran
Background & Objective: The production of plasmid-mediated AmpC beta-lactamases (PMABLs) among urinary Klebsiella pneumoniae isolates causes a severe problem to the successful treatment of urinary tract infections (UTIs). This study was designed to evaluate antimicrobial resistance, the presence of AmpC beta-lactamase genes, and the genetic relatedness among K. pneumoniae strains separated from...
متن کاملOrigin and Evolution of the AmpC -Lactamases of Citrobacter freundii
To determine whether the widespread clinical use of -lactams has been selective for Citrobacter freundiiderived alleles of plasmid ampC genes, we generated a Bayesian consensus phylogeny of the published ampC sequences and compared the MICs of 16 -lactam antibiotics for Escherichia coli strains containing cloned copies of the C. freundii ampC alleles. We found that for the majority of compounds...
متن کاملEvaluation of the β-Lactamase Disk Test Method in the Detection of Extended-Spectrum-β- Lactamases in Clinical Isolates of Multidrug-Resistant Pseudomonas aeruginosa
Background & Aims: The production of extended-spectrum-β-lactamases (ESBLs) is the main mechanism of resistance to β-lactam antibiotics. The outbreak of isolates simultaneously possessing several resistance mechanisms to β-lactam antibiotics caused a decrease in sensitivity of the confirmatory tests for ESBL. The aim of this study was the evaluation of the β-lactamase disk test method in the de...
