Crystal structure of the class A extended-spectrum β-lactamase CTX-M-96 in complex with relebactam at 1.03 Angstrom resolution.

The use of β-lactam/β-lactamase inhibitors constitutes an important strategy to counteract β-lactamases in multidrug-resistant (MDR) Gram-negative bacteria. Recent reports have described ceftazidime-/avibactam-resistant isolates producing CTX-M variants with different amino acid substitutions (e.g.

Characterization of Emerging Pathogens Carrying Gene in IncP-6 Plasmids Isolated From Urban Sewage in Argentina.

Untreated wastewater is a reservoir for multidrug-resistant bacteria, but its role in the spread of antibiotic resistance in the human population remains poorly investigated. In this study, we isolated a KPC-2-producing ST2787 subsp. (WW14A), recovered from raw sewage at a wastewater treatment plant in Argentina in 2018 and determined its complete genome sequence.
