Aztreonam Combinations with Avibactam, Relebactam, and Vaborbactam as Treatment for New Delhi Metallo-β-Lactamase-Producing Enterobacterales Infections—In Vitro Susceptibility Testing

Pharmaceuticals
Antimicrobial resistance is a major global health issue. Metallo-β-lactamases (MBL), in particular, are problematic because they can inactivate all classes of β-lactams except aztreonam.

Clinical Epidemiological Analysis of the Genotypic Spectrum and Mortality Risk in Carbapenem‐Resistant Klebsiella pneumoniae (CRKP) Infections

Canadian Journal of Infectious Diseases and Medical Microbiology, Volume 2026, Issue 1, 2026.
Background Carbapenem‐resistant Klebsiella pneumoniae (CRKP) has become a global public health threat, with significantly increased morbidity and mortality among high‐risk inpatients. High‐risk genotypes of CRKP, primarily including K. pneumoniae carbapenemase (KPC), oxacillinase‐48–like (OXA‐48–like), New Delhi metallo‐β‐lactamase (NDM), imipenemase ...

Single-Dose Pharmacokinetics and Safety of Meropenem-Vaborbactam in Subjects with Chronic Renal Impairment

, 2018
Vaborbactam is a member of a new class of β-lactamase inhibitors with inhibitory activity against serine carbapenemases (e.g., Klebsiella pneumoniae carbapenemase) that has been developed in combination with meropenem.

Mutation of kvrA causes OmpK35/36 porin downregulation and reduced meropenem/vaborbactam susceptibility in KPC-producing Klebsiella pneumoniae [PDF]

, 2020
Meropenem/vaborbactam resistance in Klebsiella pneumoniae is associated with loss of function mutations in the OmpK35 and OmpK36 porins. Here we identify two previously unknown loss of function mutations that confer cefuroxime resistance in K. pneumoniae.

Relapsing Salmonella Meningitis in an Infant: A Case Report and Review of the Literature

Case Reports in Pediatrics, Volume 2026, Issue 1, 2026.
Accurate diagnosis of bacterial meningitis is critical, particularly in young febrile infants. Although commercially available multiplex PCR assays enable rapid pathogen detection, these typically do not include Salmonella spp. or other Enterobacteriaceae, which may result in missed diagnoses and/or inappropriate treatment duration.

Genomic analysis and antimicrobial activity of β-lactam/β-lactamase inhibitors and other agents against KPC-producing Klebsiella pneumoniae clinical isolates from Brazilian hospitals

Scientific Reports, 2023
Carbapenem-resistant Klebsiella pneumoniae (CRKP) are highly disseminated worldwide, and isolates co-resistant to other antimicrobial agents pose a threat to effective antimicrobial therapy. Therefore, evaluation of novel antimicrobial drugs is needed to

Investigating the Effect of Xylitol on ompK36 Overexpression, Increased Meropenem Susceptibility, and Antibiofilm Activity in a Carbapenem‐Resistant Clinical Strain of Klebsiella pneumoniae

International Journal of Microbiology, Volume 2026, Issue 1, 2026.
Carbapenem‐resistant Klebsiella pneumoniae poses a significant public health threat due to limited therapeutic options. This study investigated the potential of xylitol, a sugar alcohol, to enhance meropenem activity and combat biofilms in a clinical carbapenem‐resistant K. pneumoniae strain (Kp5) and a standard susceptible strain (K. pneumoniae subsp.

Development of an HPLC Method for the Determination of Meropenem/Vaborbactam in Biological and Aqueous Matrixes

Journal of Chromatographic Science, 2020
Abstract A HPLC method was developed and validated to analyze meropenem and vaborbactam simultaneously in murine plasma and saline matrixes. A 60-μL volume of extracted sample was injected onto a 5-μm BDS Phenyl-Hypersil C18 reversed-phase column and analyzed with a UV detector set at 298 nm for the first 4.9 min and switched to 240 nm ...

A Review of β‐Lactamase Inhibitors in Clinical Use and Development: Mechanisms, Spectrum, and Therapeutic Applications

International Journal of Microbiology, Volume 2026, Issue 1, 2026.
β‐Lactam antibiotics have long served as a cornerstone for treating bacterial infections. However, their widespread and often indiscriminate use has fueled the emergence of multidrug‐resistant Gram‐negative pathogens, primarily through the production and dissemination of β‐lactamase enzymes.

Antimicrobial activity of ceftazidime-avibactam against KPC-2-producing Enterobacterales: a cross-combination and dose-escalation titration study with relebactam and vaborbactam

Microbiology Spectrum
With the introduction of ceftazidime-avibactam worldwide, the antimicrobial activity of new β-lactam/β-lactamase inhibitors (BL/BLIs) needs to be investigated.
