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 ...

Vibrio Community Structure Shapes the Diversity of Carbenicillin‐Hydrolysing Class A β‐Lactamase Circulating in European Coastal Environments

Environmental Microbiology, Volume 28, Issue 8, August 2026.
Vibrio communities shape carbenicillinase diversity in European coasts. Sediments serve as reservoirs of antibiotic‐resistant Vibrio alginolyticus, which can move into the water column and accumulate in bivalves. This spreads β‐lactamase resistance and raises human exposure risks to antibiotic‐resistant pathogenic Vibrio, especially as higher seawater ...

Antimicrobial Resistance of Serratia marcescens Recovered From Aquatic Environments: A Review

Environmental Microbiology Reports, Volume 18, Issue 4, August 2026.
Serratia marcescens is a gram‐negative bacillus forming biofilms and showing multidrug resistance. Review (2019–2024) included 13 studies, 90 aquatic isolates. High resistance to β‐lactams, including carbapenems. Genes: blaOXA‐48, blaTEM‐1, aac(6′)‐Ic. Aquatic environments are reservoirs, requiring monitoring and control to prevent spread.

Accumulation of Histidine Reduce the Susceptibility of Vibrio splendidus Persister Cells to Tetracycline

Environmental Microbiology Reports, Volume 18, Issue 4, August 2026.
Histidine accumulation promotes tetracycline‐induced persister formation in V. splendidus. It enhances membrane potential and upregulating the efflux pump gene, thereby reducing antibiotic susceptibility. ABSTRACT Vibrio splendidus is an opportunistic pathogen widely distributed in marine environments, animal tissues and seabed sediments. It can infect

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
