Combination of Oral Doxycycline and Rifampin for Pan‐Drug Resistant Klebsiella pneumoniae Infection: A Case Report

Clinical Case Reports, Volume 14, Issue 8, August 2026.
ABSTRACT Pan‐drug resistant Klebsiella pneumoniae is a major therapeutic challenge, particularly when standard last‐line agents are unavailable or contraindicated. We report a 45‐year‐old man with multifocal osteomyelitis and persistent purulent wound discharge despite broad‐spectrum antibiotics, repeated debridement, and two sequential amputations ...

Development of Resistance to Eravacycline by Klebsiella pneumoniae and Collateral Sensitivity-Guided Design of Combination Therapies

Microbiology Spectrum, 2022
The evolution of bacterial antibiotic resistance is exhausting the list of currently used antibiotics and endangers those in the pipeline. The combination of antibiotics is a promising strategy that may suppress resistance development and/or achieve ...

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 ...

Longitudinal Molecular Epidemiology and Genomic Surveillance of Carbapenem‐Resistant Klebsiella pneumoniae in the Gut of Healthy Individuals in China

MedComm, Volume 7, Issue 8, August 2026.
Using 16,040 stool samples from healthy individuals across 30 Chinese provinces (2016–2024), we performed longitudinal genomic surveillance of carbapenem‑resistant Klebsiella pneumoniae (CRKP) colonizing the gut. We reveal rising community CRKP prevalence, especially in southern China, a shift from blaKPC‐2 to plasmid‑borne blaNDM‐5 on IncHI2/IncHI2A ...

Tissue and Serum Concentrations of Time‐Dependent Antibiotics in Infected Diabetic Foot Ulcers by Bolus or Continuous Administration: The Randomised DFIATIM Trial

Diabetes/Metabolism Research and Reviews, Volume 42, Issue 5, July 2026.
ABSTRACT Aims The clinical effectiveness of antibiotic (ATB) therapy in patients with infected diabetic foot ulcers (iDFUs) depends on achieving sufficient ATB concentrations in both serum and peripheral tissues. This study evaluated the availability and bactericidal activity of the time‐dependent ATBs—ceftazidime (CTZ) and amoxicillin/clavulanate (AMC)
