Antimicrobial resistance (AMR), frequently considered a major global public health threat, requires comprehensive understanding of its emergence, mechanisms, advances, and implications. AMR’s epidemiological landscape is characterized by widespread prevalence constantly evolving patterns, with multidrug-resistant organisms (MDROs) creating new challenges every day. The most common mechanisms underlying AMR (i.e., genetic mutations, horizontal gene transfer, selective pressure) contribute to the emergence dissemination resistant strains. Therefore, mitigation strategies (e.g., antibiotic stewardship programs—ASPs—and infection prevention control strategies—IPCs) emphasize importance responsible antimicrobial use surveillance. A One Health approach interconnectedness human, animal, environmental health) highlights necessity for interdisciplinary collaboration holistic in combating AMR. Advancements novel therapeutics alternative agents vaccines) offer promising avenues addressing challenges. Policy interventions at international national levels also promote ASPs aiming regulate use. Despite all observed progress, remains pressing concern, demanding sustained efforts address emerging threats sustainability.

Objectives: Bacterial infections, mainly due to rising antimicrobial resistance (AMR), are an immense global health threat, complicating treatment, prolonging illness, and increasing mortality. The WHO lists AMR as one of the major threats human health. Biofilm plays a crucial role in AMR, protecting bacteria promoting resistance. Targeting biofilms improves antibiotic efficacy reduces chronic infections. Titanium dioxide nanoparticles (TiO2-NPs) have emerged promising candidate drug delivery, diagnostics, therapies their distinctive properties. Methods: Due challenge potential green-synthesized nanoparticles, this study investigates antibiofilm activity intracellular ROS production by TiO2-NPs produced from Linum usitatissimum seed extract.
