The characterization of a new stabilized lactonase from the endophytic fungi Aspergillus pseudonomiae with anti‐bacterial and anti‐fungal properties

Protein Science, Volume 35, Issue 8, August 2026.
Abstract Microorganisms use diverse small‐molecule signals to coordinate behavior, supporting interspecies and interkingdom communication. These chemical dialogs shape fundamental biological processes and define interactions from cooperation to antagonism.

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 ...

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

Breakthrough Advances in Beta-Lactamase Inhibitors: New Synthesized Compounds and Mechanisms of Action Against Drug-Resistant Bacteria

Pharmaceuticals
Beta-lactam drugs hold a central place in the antibacterial arsenal, and the production of beta-lactamases by drug-resistant bacteria has severely compromised the effectiveness of nearly all available beta-lactams.

Molecular characterization and clinical significance of New Delhi metallo-beta-lactamases-1 producing Escherichia coli recovered from a South Indian tertiary care hospital

Indian Journal of Pathology and Microbiology, 2015
Context: The increased rate of infection by New Delhi metallo-beta-lactamases-1 (NDM1) producing Escherichia coli is a major concern since they show a high rate of drug resistance and are responsible for mortality and morbidity. Aims: To characterize the

Metallo-beta-lactamases of Pseudomonas aeruginosa--a novel mechanism resistance to beta-lactam antibiotics.

Folia Histochemica et Cytobiologica, 2008
Since about twenty years, following the introduction into therapeutic of news beta-lactam antibiotics (broad-spectrum cephalosporins, monobactams and carbapenems), a very significant number of new beta-lactamases appeared.
