The NitroSpeed-Carba NP test was used to rapidly detect and discriminate between the different types of carbapenemases (classes A, B, and D) within 30 minutes among a collection of 202 Pseudomonas sp. strains (mostly Pseudomonas aeruginosa). A total of 99 carbapenemase–(including enzymes exhibiting weak carbapenemase activity such as several Guyana Extended-Spectrum (GES)-ß-lactamases) and...

Objectives: To evaluate the in vivo efficacy of a dual carbapenem combination containing imipenem plus meropenem against carbapenem-resistant Acinetobacter baumannii producing carbapenemases OXA-23 or OXA-58.Methods: An experimental model of peritonitis using C57BL/6J female mice was developed and the minimum lethal doses were calculated for infections due to OXA-23 or OXA-58 producers of A. ...

Background: Carbapenemase-producing Gram-negative bacteria cause infections that are difficult to treat and represent a rising threat to healthcare systems worldwide. This study analysed isolates of Escherichia coli (E. coli), a species associated with nosocomial-acquired and community-acquired infections, from hospitals in Germany and Switzerland exhibiting a slight decrease in...

A series of clinical NDM-5-producing E. coli isolates obtained from two surveillance networks of carbapenem-producing Enterobacterales from 2018-2019, namely Switzerland (NARA) and Germany (SurvCARE), were analyzed. The 33 NDM-5- producing E. coli isolates were highly resistant to β-lactams including the novel ß- lactam/ß-lactamase inhibitor combinations (ceftazidime/avibactam, ...

Unlike for classes A and B, a standardized amino acid numbering scheme has not been proposed for the class C (AmpC) β-lactamases, which complicates communication in the field. Here, we propose a scheme developed through a collaborative approach that considers both sequence and structure, preserves traditional numbering of catalytically important residues (Ser64, Lys67, Tyr150, and Lys315),...

Objectives: To evaluate the biochemical Rapid ESBL NP® (Liofilchem, Italy) for the rapid detection of extended-spectrum β-lactamases (ESBLs) in Enterobacterales.Methods: A total of 100 clinical gram-negative strains (40 ESBL producers with or without cephalosporinase, 43 carbapenemase producers with or without additional ESBLs, 8 AmpC-type producers, 6 penicillinase producers, and 3 ...
