Carbapenemases are β-lactamases with versatile hydrolytic capacities. They have the ability
to hydrolyze penicillins, cephalosporins, monobactams, and carbapenems. Bacteria …

The ascendancy of metallo-β-lactamases within the clinical sector, while not ubiquitous, has
nonetheless been dramatic; some reports indicate that nearly 30% of imipenem-resistant …

Klebsiella pneumoniae (KP) is a nosocomial pathogen causing difficult-to-treat infections.
The presence of virulence genes and antibiotic resistance of 109 KP isolates from …

Strains of Enterobacteriaceae producing an extended spectrum β‐lactamase have become
a concern in medical bacteriology as regards both antimicrobial treatment and infection …

Gram-negative bacilli with acquired metallo-β-lactamase (MBL) production have been
increasingly reported in some countries, necessitating their detection. The aim of this study …

Acquired carbapenemases are emerging resistance determinants in Gram-negative
pathogens, including Enterobacteriaceae, Pseudomonas aeruginosa and other Gram …

Carbapenemase-producing bacteria have now spread all over the world. Infections caused
by those bacteria are difficult to treat. Therefore, there is an urgent need for accurate and fast …

Abstract β-Lactams are the most widely used antibiotics, and β-lactamases are the greatest
source of resistance to them. An understanding of β-lactamase detection and identification is …

ABSTRACT Metallo-β-lactamases (MBLs) have been increasingly recognized from clinical
isolates worldwide, but the laboratory detection of these strains is not well defined. We report …

Purpose Carbapenems are considered the most efficient antibiotic used in the treatment of
nosocomial infections. Carbapenem-resistant Gram-negative rods are becoming a serious …
