Antibiotic Resistance and Biofilm‐Forming Capacity of Oral Biofilm Bacteria in Patients With Periodontitis and Healthy Individuals

MicrobiologyOpen, Volume 15, Issue 5, October 2026.
Key finding: Antimicrobial resistance was common across all groups and associated with biofilm‐forming capacity, an association that remains observational and species‐confounded. ABSTRACT This study aimed to analyse antimicrobial resistance (AMR) in bacterial isolates from subgingival biofilms of patients with periodontitis and supragingival biofilms ...

Bacteria‐Responsive Nanostructured Drug Delivery Systems for Targeted Antimicrobial Therapy

Advanced Materials, Volume 38, Issue 51, 11 September 2026.
Bacteria‐responsive nanocarriers are designed to release antimicrobials only in the presence of infection‐specific cues. This selective activation ensures drug release precisely at the site of infection, avoiding premature or indiscriminate release, and enhancing efficacy.

Outer membrane permeability of mcr-positive bacteria reveals potent synergy of colistin and macromolecular antibiotics against colistin-resistant Acinetobacter baumannii

Frontiers in Microbiology
Colistin (CT) is the last-resort of antibiotic against multidrug-resistance (MDR) Acinetobacter baumannii (A. baumannii) infection. However, colistin resistance is increasingly reported in A.
