Colistin-resistant Pseudomonas aeruginosa clinical strains with defective biofilm formation

GMS Hygiene and Infection Control, 2019
Aim: Colistin is the only effective antibiotic in some cases of resistance to all tested antibiotics, even carbapenem. On the other hand, biofilm formation is one of the antibiotic resistance mechanisms in this bacterium.

Effect of Green‐Synthesized Silver Nanoparticles From Nepeta pogonosperma and Astrodaucus persicus on the Reduction of Bap Gene Expression in Strong Biofilm‐Producing Acinetobacter baumannii Clinical Isolates

MicrobiologyOpen, Volume 15, Issue 5, October 2026.
Green‐synthesized silver nanoparticles from Nepeta pogonosperma and Astrodaucus persicus significantly inhibit biofilm formation and downregulate bap gene expression in multidrug‐resistant clinical isolates of Acinetobacter baumannii. This eco‐friendly approach offers a promising strategy to combat antimicrobial resistance.

Colistin Resistance Development Following Colistin-Meropenem Combination Therapy Versus Colistin Monotherapy in Patients With Infections Caused by Carbapenem-Resistant Organisms

Clinical Infectious Diseases, 2019
Abstract Background We evaluated whether carbapenem-colistin combination therapy reduces the emergence of colistin resistance, compared to colistin monotherapy, when given to patients with infections due to carbapenem-resistant Gram-negative organisms.

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 ...

Postoperative Takotsubo Cardiomyopathy in a Young Woman: A Case Report

Clinical Case Reports, Volume 14, Issue 9, September 2026.
Timeline of the patient's clinical course. ABSTRACT Takotsubo cardiomyopathy (TCM) can occur in young adults exposed to extreme physical stress, such as surgery, sepsis, and transfusion reactions. Mechanical recovery may precede electrical normalization, with ECG abnormalities persisting despite improved left ventricular ejection fraction (LVEF). Early
