Biochemical characterization of the carbapenem-hydrolyzing β-lactamase AsbM1 fromAeromonas sobriaAER 14M: a member of a novel subgroup of metallo-β-lactamases [PDF]

FEMS Microbiology Letters, 1996
AsbM1, a carbapenem-hydrolyzing beta-lactamase produced by Aeromonas sobria AER 14M, was purified chromatographically, with anion exchange chromatography performed in the absence of Zn2+. The molecular mass of AsbM1 was approximately 34,000; the isoelectric point was 9.1.

Metallo-β-Lactamases and Aptamer-Based Inhibition

Pharmaceuticals, 2011
An evolution of antibiotic-resistant bacteria has resulted in the need for new antibiotics. β-Lactam based drugs are the most predominantly prescribed antibiotics to combat bacterial infections; however, production of β-lactamases, which catalyze the ...

Prevalence and detection of Stenotrophomonas maltophilia carrying metallo-β-lactamase blaL1 in Beijing, China [PDF]

Frontiers in Microbiology, 2014
Intrinsic β-lactam resistance in Stenotrophomonas maltophilia is caused by bla L1 and/or bla L2, a kind of metallo-β-lactamase with a broad substrate spectrum including carbapenems. A rapid and sensitive molecular method for the detection of bla L1 in clinical samples is needed to guide therapeutic treatment. In present study, we first described a loop-

Genomic Characterization of Mutli-Drug Resistant Pseudomonas aeruginosa Clinical Isolates: Evaluation and Determination of Ceftolozane/Tazobactam Activity and Resistance Mechanisms

Frontiers in Cellular and Infection Microbiology, 2022
Resistance to ceftolozane/tazobactam (C/T) in Pseudomonas aeruginosa is a health concern. In this study, we conducted a whole-genome-based molecular characterization to correlate resistance patterns and β-lactamases with C/T resistance among multi-drug ...

Detection of metallo-β-lactamase gene blaIMP of Escherichia coli clinical isolates in Sanglah General Hospital Bali

Indonesia Journal of Biomedical Science, 2019
Background: Escherichia coli belong to the family of Enterobacteriaceae that are responsible as one of the leading cause of nosocomial infections. The emergence of Carbapenem-resistant Enterobacteriaceae presents therapeutic challenges for clinicians on choosing the correct type of antibiotics to prescribe.

Molecular characterization ofbla_IMP-5, a new integron-borne metallo-β-lactamase gene from anAcinetobacter baumanniinosocomial isolate in Portugal [PDF]

FEMS Microbiology Letters, 2002
Acinetobacter baumannii 65FFC, an imipenem-resistant clinical strain, isolated from the urine of a patient at the Coimbra University Hospital, Portugal, in 1998, produced a metallo-beta-lactamase with a calculated pI 9.3. The isolate was highly resistant to penicillins, broad-spectrum cephalosporins, including ceftazidime, ceftriaxone, cefepime ...

Evolution of Metallo-β-lactamases: Trends Revealed by Natural Diversity and in vitro Evolution

Antibiotics, 2014
The production of β-lactamase enzymes is one of the most distributed resistance mechanisms towards β-lactam antibiotics. Metallo-β-lactamases constitute a worrisome group of these kinds of enzymes, since they present a broad spectrum profile, being able

Production of metallo-β-lactamase among Pseudomonas aeruginosa strains isolated in the State of Sergipe, Brazil

Revista da Sociedade Brasileira de Medicina Tropical, 2015
INTRODUCTION: Acquired production of metallo-β-lactamases is an important mechanism of resistance in Pseudomonas aeruginosa. The objective of this study was to investigate the production of metallo-β-lactamase and the genetic diversity among ceftazidime ...

Molecular heterogeneity ofbla_VIM-2-containing integrons fromPseudomonas aeruginosaplasmids encoding the VIM-2 metallo-β-lactamase [PDF]

FEMS Microbiology Letters, 2001
A bla(VIM-2) metallo-beta-lactamase determinant, identical to that previously identified in Pseudomonas aeruginosa COL-1 isolate from a French hospital, was detected on a 28-kb plasmid carried by a nosocomial isolate of P. aeruginosa from Verona, Italy.
