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 ...

Occurrence and Distribution of Environmental Pseudomonas aeruginosa From Hospitals in Bangladesh Reveals Diverse Strain Families, Multidrug Resistance, and Biofilm Formation

Environmental Microbiology Reports, Volume 18, Issue 4, August 2026.
Environmental reservoirs in Bangladeshi hospitals harbor phylogenetically diverse, multidrug‐resistant Pseudomonas aeruginosa with extensive biofilm‐forming capacity and class 1 integron‐associated resistance genes. These findings highlight hospital environments as persistent sources of antimicrobial resistance dissemination and underscore the need for

Eco‐Geography Reverses Dominant AMR Reservoirs in Klebsiella pneumoniae: Integron‐Rich Mobilomes and Cross‐Niche Connectivity

Advanced Science, Volume 13, Issue 42, 28 July 2026.
Dominant antimicrobial resistance reservoirs in Klebsiella pneumoniae vary across eco‐geographic settings rather than following a universal pattern. Integrated One Health and global genomic analyses show that lineage structure, integron load, and cross‐niche connectivity shape whether AMR burden accumulates primarily in human or nonhuman compartments ...
