Green Synthesis of ZnO Nanoparticles From Spirulina platensis: Antimicrobial and Cytotoxic Evaluation With Molecular Docking Studies

ChemistryOpen, EarlyView.
Algal‐extract‐derived ZnO nanoparticles show shape anisotropy and are bio capped by phytochemicals. These green‐synthesized NPs strongly inhibit S. aureus and K. pneumoniae biofilms. Molecular docking suggests stable binding of surface biomolecules to microbial targets, highlighting synergistic antibacterial mechanisms.

Human metallo-β-lactamase enzymes degrade penicillin

Scientific Reports, 2019
Nonribosomal peptides are assemblages, including antibiotics, of canonical amino acids and other molecules. β-lactam antibiotics act on bacterial cell walls and can be cleaved by β-lactamases.

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

Veterinary Record, EarlyView.
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.

In Vivo Resistance to Ceftolozane/Tazobactam in Pseudomonas aeruginosa Arising by AmpC- and Non-AmpC-Mediated Pathways

Case Reports in Infectious Diseases, 2018
Two pairs of ceftolozane/tazobactam susceptible/resistant P. aeruginosa were isolated from 2 patients after exposure to β-lactams. The genetic basis of ceftolozane/tazobactam resistance was evaluated, and β-lactam-resistant mechanisms were assessed by ...

Reusing health records from farm animal practices at scale: A potential complementary method of surveillance

Veterinary Record, EarlyView.
Abstract Background Disease in primary care frequently represents a surveillance blind spot, particularly for diseases affecting farm animals. Methods Electronic health records (EHRs) were collected from four farm animal veterinary practices in Wales (February 2024‒January 2025) as part of a pilot study.

The small protein CydX is required for function of cytochrome bd oxidase in Brucella abortus. [PDF]

, 2012
A large number of hypothetical genes potentially encoding small proteins of unknown function are annotated in the Brucella abortus genome. Individual deletion of 30 of these genes identified four mutants, in BAB1_0355, BAB2_0726, BAB2_0470, and BAB2_0450
