Study of Streptomyces β-lactamase [PDF]

, 1990
β-lactamases play an important part in the resistance of many bacteria to β-lactam antibiotics. This degradative enzyme hydrolyses the amide bond in the β-lactam ring of susceptible penicillins and cephalosporins.

A structured, behavioural science approach to the preparation of antimicrobial stewardship interventions for companion animal veterinarians

Veterinary Record, Volume 198, Issue 12, Page e521-e532, 13–27 June 2026.
Abstract Background A structured, behavioural science approach was adopted to develop antimicrobial stewardship interventions in UK first‐opinion companion animal veterinary practice. The objectives were to identify behavioural targets for intervention and to understand how practice contexts influence these behaviours.

Metabolism‐Based Biomarkers for Rapid Phenotypic Antibiotic Susceptibility Testing

Advanced Science, Volume 13, Issue 33, 15 June 2026.
Metabolic differences emerging after antibiotic exposure provide rapid phenotypic signals of susceptibility and resistance. This review summarizes metabolic biomarkers for rapid phenotypic AST, associated with nutrient uptake, respiratory activity, metabolic reprogramming, and enzymatic function. ABSTRACT The accelerating global crisis of antimicrobial

Population pharmacokinetic modelling of amoxicillin in human breast milk—A contribution from the ConcePTION project

British Journal of Clinical Pharmacology, Volume 92, Issue 6, Page 1833-1844, June 2026.
Aims Amoxicillin, a widely used β‐lactam antibiotic, requires improved pharmacokinetic characterization during breastfeeding. This study used a population pharmacokinetic (PopPK) approach to model amoxicillin concentrations in breast milk, identify variability sources and estimate infant exposure, applying worst‐case scenarios.

Fusobacterium nucleatum in cancer: Interactions with microbiota, tumour colonisation and cancer progression

Clinical and Translational Medicine, Volume 16, Issue 6, June 2026.
F. nucleatum colonises tumours through mucosal translocation, adjacent‐tissue migration and hematogenous dissemination. It promotes cancer progression via adhesion, inflammation, immune evasion, epigenetic remodelling and metastasis. Its effects on therapy response are tumour‐context dependent. Microbiome‐guided targeting may enable precision oncology.
