Molecular and Biochemical Characterization of VEB-1, a Novel Class A Extended-Spectrum β-Lactamase Encoded by an Escherichia coli Integron Gene A clinical isolate, Escherichia coli MG-1, isolated from a 4-month-old Vietnamese orphan child, produced a beta-lactamase conferring resistance to extend...
Mechanism and properties of resistance plasmids; Ceftazidime resistance caused by a broad-spectrum TEM-10 beta-lactamase; Cephalosporin-resistant bacterial isolates and fluoroquinolone antibiotics; Ciprofloxacin hydrochloride use; Suggestion to prevent the spread of extended-spectrum beta-lactamase-containing ...
Extended-spectrum beta-lactamase. These enzymes can hydrolyzepenicillins, broad-spectrumcephalosporins, andmonobactamsand are typically produced by members of the familyEnterobacteriacae, which includesE. coliandKlebsiellapneumonia.Infections caused by organisms producing ESBLs are treated withcarbapenemsas a...
horizonpress.com/cimb !13 Extended Spectrum Beta-lactamases lactamase are derived from SHV-1. Most strains have SHV on their plasmid through the replacement of serine to glycine at position 238. In addition, some strains change lysine to glutamate at position 240. The serine residue at position...
Extended-spectrum β-lactamases (ESBLs) were discovered in Europe in the early 1980s after widespread use of broad-spectrum antibiotics. They are largely derivatives of 3 progenitor β-lactamases that confer resistance to ampicillin in gram-negative bacteria and are now carried on plasmids. Substitut...
Resistance to broad spectrum 尾 lactams, mediated by extended spectrum beta lactamase (ES尾L) is an increasing problem worldwide. Production of these enzymes in clinical infections can result in treatment failure if one of the second or third generation cephalosporins is used. This study ...

Extended-spectrum beta-lactamase producing (ESBL) Klebsiella pneumoniae is an important cause of nosocomial infections in neonatal intensive care units (NICUs). Our objectives were to determine (1) the incidence of ESBL K. pneumoniae in our NICU, (2) the
