Occurrence and Detection of AmpC Beta-Lactamases among Escherichia coli, Klebsiella pneumoniae, and Proteus mirabilis Isolates at a Veterans Medical Center
ABSTRACT AmpC beta-lactamases are cephalosporinases that confer resistance to a wide variety of β-lactam drugs and that may thereby create serious therapeutic problems. Although reported with… Expand

AmpC Disk Test for Detection of Plasmid-Mediated AmpC β-Lactamases in Enterobacteriaceae Lacking Chromosomal AmpC β-Lactamases
ABSTRACT Although plasmid-mediated AmpC β-lactamases were first reported in the late 1980s, many infectious disease personnel remain unaware of their clinical importance. These enzymes are typically… Expand

β-Lactamases Responsible for Resistance to Expanded-Spectrum Cephalosporins in Klebsiella pneumoniae, Escherichia coli, and Proteus mirabilis Isolates Recovered in South Africa
ABSTRACT Although resistance to the expanded-spectrum cephalosporins among members of the family Enterobacteriaceae lacking inducible β-lactamases occurs virtually worldwide, little is known about… Expand

Detection of extended-spectrum-beta-lactamase-producing members of the family Enterobacteriaceae with Vitek ESBL test.
A three-phase analysis of the Vitek ESBL test and a double-disk (2 disk) test was performed to assess their ability to detect extended-spectrum beta-lactamases (ESBLs) in members of the family… Expand

Molecular characterization of a multiply resistant Klebsiella pneumoniae encoding ESBLs and a plasmid-mediated AmpC.
Organisms encoding multiple antibiotic resistance genes are becoming increasingly prevalent. In this report we describe a multiply resistant Klebsiella pneumoniae which possesses at least five… Expand

Occurrence and detection of extended-spectrum beta-lactamases in members of the family Enterobacteriaceae at a veterans medical center: seek and you may find.
A total of 907 consecutive isolates of members of the family Enterobacteriaceae recovered during a 20-week period were tested for production of extended-spectrum beta-lactamases (ESBLs) by the… Expand

Plasmid-Mediated Carbapenem-Hydrolyzing Enzyme KPC-2 in an Enterobacter sp
ABSTRACT A strain of an Enterobacter sp. with reduced susceptibility to imipenem, which produced a plasmid-mediated class A carbapenem-hydrolyzing enzyme, KPC-2 β-lactamase, was isolated from a… Expand

Discovery of CTX-M-Like Extended-Spectrum β-Lactamases in Escherichia coli Isolates from Five U.S. States
The most commonly reported extended-spectrum β-lactamases (ESBLs) in U.S. isolates of Escherichia coli are TEM and SHV derived (2). CTX-M ESBLs have been reported elsewhere, mostly for clinical… Expand

Kinetics Study of KPC-3, a Plasmid-Encoded Class A Carbapenem-Hydrolyzing β-Lactamase
ABSTRACT The kinetic activity of KPC-3, a plasmid-encoded class A carbapenemase, was studied. It hydrolyzed penicillins, cephalosporins, carbapenems, and even sulbactam. The best substrate was… Expand
