Emergence of Ceftazidime‐Avibactam‐Induced KPC Variants (KPC‐25/127) in Intracranial Infection and Implications for Clinical Management

MicrobiologyOpen, Volume 15, Issue 4, August 2026.
Novel KPC‐25 and first‐reported KPC‐127 sequentially evolved in one patient under CAZ‐AVI pressure, distinct mutations remodel enzyme activity to drive differential multidrug resistance. ABSTRACT The emergence of novel Klebsiella pneumoniae carbapenemase (KPC) variants contributing to clinical treatment failure poses a substantial threat to public ...

Case report: Continuous infusions of ceftazidime-avibactam and aztreonam in combination through elastomeric infusors for 12 weeks for the treatment of bone and joint infections due to metallo-β-lactamase producing Enterobacterales

Frontiers in Medicine, 2023
Among carbapenem-resistant Enterobacterales, metallo-beta-lactamase producing strains represent a growing therapeutic challenge. While the association of aztreonam and ceftazidime-avibactam has been investigated in recent years for the treatment of ...

Effects of Nacubactam and Its Metabolites on QTc Interval: A Pooled Analysis of Two Randomized Phase 1 Studies

Clinical and Translational Science, Volume 19, Issue 6, June 2026.
ABSTRACT Nacubactam is a β‐lactamase inhibitor. Early‐phase studies with 1000/2000/4000/8000 mg nacubactam monotherapy were not powered to assess proarrhythmic risk. Therefore, this analysis pooled electrocardiogram data from two placebo‐controlled studies to quantify potential effects of nacubactam on cardiac repolarization.

Zwitterionic Penicillin‐Derived Sulfone Inhibitor for Combating β‐Lactamase‐Mediated Antibiotic Resistance

ChemMedChem, Volume 21, Issue 9, 14 May 2026.
Combining enhanced permeability strategies with (2‐pyridyl)methylene substitution in the sulbactam scaffold led to a novel β‐lactamase inhibitor to combat β‐lactamase‐mediated resistance to β‐lactam antibiotics. The studies presented highlight the potential of compound 3 as a next‐generation β‐lactamase inhibitor for combating infections caused by ...

Emergence and Genomic Characterization of a Hypervirulent Klebsiella pneumoniae Isolate From a New Clone in Brazil

Microbiology and Immunology, Volume 70, Issue 5, Page 261-267, May 2026.
ABSTRACT Hypervirulent Klebsiella pneumoniae (hvKp) has emerged globally as a major public health concern, often associated with severe community‐acquired and healthcare‐associated human infections. Despite alerts from PAHO/WHO on convergent hvKp strains with multidrug resistance in Latin America, comprehensive data from Brazil, the region's largest ...

Characterization of Metallo β-Lactamase Producing Enterobacterales Isolates with Susceptibility to the Aztreonam/Avibactam Combination. [PDF]

Antibiotics (Basel)
Background/Objectives: Metallo-β-lactamases (MBLs) in Enterobacterales and other Gram-negative organisms pose significant public health threats due to their association with multidrug resistance (MDR). Although aztreonam (AZT) can target MBL-producing organisms, its efficacy is compromised in organisms expressing additional β-lactamases that inactivate

Clinical Outcome Associated With Beta‐Lactam Allergy Labels in Hospitalized Patients in Belgium

Clinical and Translational Allergy, Volume 16, Issue 4, April 2026.
ABSTRACT Background In the United States, beta‐lactam allergy labels (BLAL) are documented in 9%–16% of hospitalized patients and associated with worse clinical outcomes such as increased mortality, length of hospital stay (LOS), intensive care unit (ICU) admission, and use of alternative antibiotics, providing an incentive for broad delabeling ...

The Evaluation of Machine Learning Models Using Matrix‐Assisted Laser Desorption/Ionization Time‐of‐Flight Mass Spectrometry (MALDI–TOF–MS) Spectra for the Prediction of Antibiotic Resistance in Klebsiella pneumoniae

MicrobiologyOpen, Volume 15, Issue 2, April 2026.
Machine learning models developed from matrix‐assisted laser desorption/ionization time‐of‐flight mass spectrometry spectra can rapidly predict antimicrobial resistance in Klebsiella pneumoniae. By transforming routine spectral data into accurate resistance profiles within minutes, this approach could reduce diagnostic delays and support earlier ...
