Separation of plasmid-mediated extended spectrum β-lactamases by fast protein liquid chromatography (FPLC system) [PDF]

FEMS Microbiology Letters, 1990
We have devised a reliable procedure for the separation of three beta-lactamases of isoelectric focusing points (pI), 5.4, 6.5, and 7.9 by Fast Protein Liquid Chromatography (FPLC System). All of these enzymes were transferable and originated from a ceftazidime and cefotaxime resistant Klebsiella pneumoniae isolated in Bombay, India.

Characterization of extended-spectrum-β-lactamase (CTX-M-15)-producing strains ofSalmonella entericaisolated in France and Senegal [PDF]

FEMS Microbiology Letters, 2004
Three clinical isolates of Salmonella enterica recovered between 2000 and 2003 in France and Senegal were found to produce extended-spectrum beta-lactamase CTX-M-15. The two isolates from Senegal were recovered from stool of a hospitalized patient with gastroenteritis in 2000 and from an urine specimen of an out-patient with urinary tract infection in ...

Multi-Drug-Resistant Gram-Negative Microorganisms: Epidemiology, Treatment and Alternative Approach

Antibiotics, 2022
The presence of enzymes such as Extended-Spectrum β-lactamase (ESBL) and carbapenemases (KPCs, Metallo β-lactamases and OXA) constitutes the principal resistance mechanism to antibiotics [...]

Mutations in theampCpromoter ofEscherichia coliisolates resistant to oxyiminocephalosporins without extended spectrum β-lactamase production [PDF]

FEMS Microbiology Letters, 1999
Escherichia coli strains showing an increased resistance to oxyiminocephalosporins without an extended spectrum beta-lactamase production have been screened for mutations in their ampC beta-lactamase gene promoter. Mutations were found by direct sequencing of seven promoters at positions -42, -32 (box -35), -18, -1, +5, +24 (attenuator), +31 ...

Dutch patients, retail chicken meat and poultry share the same ESBL genes, plasmids and strains [PDF]

, 2011
Intestinal carriage of extended-spectrum beta-lactamase (ESBL) -producing bacteria in food-producing animals and contamination of retail meat may contribute to increased incidences of infections with ESBL-producing bacteria in humans.

Nationwide Study of Escherichia coli and Klebsiella pneumoniae Producing Extended-Spectrum β-Lactamases in Spain [PDF]

Antimicrobial Agents and Chemotherapy, 2005
ABSTRACT Clonal dissemination of extended-spectrum β-lactamases (ESBL) in 170 Escherichia coli isolates and 70 Klebsiella pneumoniae isolates from a nationwide study of 40 Spanish centers in 2000 was not observed in most centers. The most prevalent ESBL were CTX-M-9 (27.3%), SHV-12 (
