Industry survey of Great Britain‐sourced broilers for extended‐spectrum beta‐lactamase and Amp C beta‐lactamase‐producing Escherichia coli

Veterinary Record, 2016
ANTIBIOTIC resistance is a major concern for both human and animal populations (WHO 2014). A major reason for resistance of Enterobacteriaceae to the more recently developed β-lactam antibiotics is due to the selection of genes for the production of extended spectrum β-lactamases (ESBLs) and AmpC β-lactamases (Dhanji and others 2010).

Terminal truncations in Amp C β‐lactamase from a clinical isolate of Pseudomonas aeruginosa

European Journal of Biochemistry, 1999
AmpC β‐lactamases from strains of Pseudomonas aeruginosa have previously been shown to be heterogeneous with respect to their isoelectric point (pI). In order to elucidate the origin of this heterogeneity enzymes were isolated from a clinical isolate of a multiresistant P. aeruginosa strain and biochemically characterized.

A nosocomial outbreak of Serratia marcescens producing inducible Amp C-type beta-lactamase enzyme and carrying antimicrobial resistance genes within a class 1 integron

Journal of Hospital Infection, 2004
We investigated an outbreak of Serratia marcescens in the adult intensive care unit of the University Hospital of Napoli. The outbreak involved 13 cases of infection by S. marcescens over a nine-month period and was caused by a single pulsed-field gel electrophoresis clone.

Structural insight into the binding mode of cefotaxime and meropenem to TEM-1, SHV-1, KPC-2, and Amp-C type beta-lactamases

Cell Biochemistry and Biophysics
Antimicrobial resistance is an emerging threat to public health around the world. The study employs computational and biophysical methods to investigate the properties of cefotaxime and meropenem's binding to various beta-lactamases like TEM-1, SHV-1, KPC-2, and Amp-C. The enzyme kinetics of purified proteins revealed an increase in Michaelis constant (

A Clinical Strain of Escherichia coli Possessing CMY-2 Plasmid-Mediated Amp C β -Lactamase: An Emerging Concern in Pediatrics?

Microbial Drug Resistance, 2002
A 5-year-old child was colonized by an isolate of Escherichia coli that transferred resistance to third-generation cephalosporins and cefoxitin. This resistance phenotype was encoded on a >75-kb plasmid pLRM 22. The transferable plasmid contained both bla

Inducible amp C β-lactamase producing gram-negative bacilli from blood stream infections: Frequency, antimicrobial susceptibility, and molecular epidemiology in a national surveillance program (SCOPE)

Diagnostic Microbiology and Infectious Disease, 1997
A surveillance study of nosocomial blood stream infections [Surveillance and Control of Pathogens of Epidemiologic Importance (SCOPE)] was conducted during a 14-month period in 1995 to 1996 in approximately 50 American medical centers. Among the 4725 blood stream infections, the etiologic agent was Enterobacter spp.

Important and Emerging β-Lactamase-mediated Resistances in Hospital-based Pathogens: The Amp C Enzymes

Diagnostic Microbiology and Infectious Disease, 1998
Resistance to third-generation cephalosporins mediated by beta-lactamases is an increasing problem for clinical therapeutics. A wide range of Enterobacteriaceae produce these AmpC enzymes (Bush-Jacoby-Medeiros group 1), including Enterobacter spp., Citrobacter freundii, Morganella morganii, Providencia spp., and Serratia marcescens. Resistance via this

Detection of Amp C Beta Lactamases in Clinical Isolates of Escherichia coli and Klebsiella

2011
Detection of AmpC-mediated resistance in Gram negative organisms poses a problem due to misleading results in phenotypic tests. There are no recommended guidelines for detection of this resistance mechanism and there is a need to address this issue as much as the detection of extended spectrum beta lactamases (ESBLs) since both may co-exist and mask ...
