Heterogeneous colistin-resistance phenotypes coexisting in stenotrophomonas maltophiliaisolates influence colistin susceptibility testing

, 2021
The polymyxin antibiotic colistin shows in vitro activity against Stenotrophomonas maltophilia. However, an increased incidence of colistin-resistant isolates has been recently observed.

Penfluridol synergizes with colistin to reverse colistin resistance in Gram-negative bacilli

Scientific Reports
The growing prevalence of antibiotic resistance in multidrug-resistant Gram-negative bacteria (MDR-GNB), exacerbated by the misuse of antibiotics, presents a critical global health challenge. Colistin, a last-resort antibiotic for severe MDR-GNB infections, has faced diminishing efficacy due to the emergence of colistin-resistant (COL-R) strains.

Comparative Neurotoxicity of Polymyxin B and Colistin in Patients With Cancer

Pharmacotherapy: The Journal of Human Pharmacology and Drug Therapy, Volume 46, Issue 10, October 2026.
ABSTRACT Background The polymyxins, polymyxin B and colistin, are last‐line options for the treatment of infections caused by drug‐resistant gram‐negative organisms. The comparative neurotoxicity of these agents using contemporary dosing is poorly understood.

Colistin-stimulated ROS production is significantly impaired by the presence of colistin resistance-conferring proteins (EptA/MCR-1/ICR-Mo).

, 2018
A & B Accumulation of hydrogen peroxide is boosted by colistin stress in E. coli. C & D The presence of plasmid-borne EptA inhibits colistin-induced production of hydrogen peroxide in E. coli.

Mixed Invasive Aspergillus–Mucorales Pulmonary Coinfection in a Diabetic Patient: An Uncommon Dual Fungal Pneumonia and Literature Review

Respirology Case Reports, Volume 14, Issue 10, October 2026.
Our case describes a rare lung co‐infection caused by Aspergillus and Mucorales in a 61‐year‐old man with uncontrolled diabetes and chronic kidney disease. The diagnosis was made by BAL PCR and biopsy. Despite antifungal treatment, the patient worsened and died.

Polymersome‐Enabled Multimodal Delivery of Tobramycin and Doripenem for Targeted Eradication of Pseudomonas aeruginosa Biofilms in Chronic Rhinosinusitis

Small, Volume 22, Issue 60, 27 October 2026.
Schematic representation of diffusion‐based versus pH‐triggered drug release within a bacterial biofilm. In diffusion‐based systems, drug cargo is gradually released independent of local pH, resulting in rapid burst release and reduced sustained concentrations.

Carriage of antimicrobial‐resistant E. coli in urban stray cats (Felis catus)

Australian Veterinary Journal, Volume 104, Issue 10, Page 681-688, October 2026.
Antimicrobial resistance (AMR) in Escherichia coli is a growing concern in both human and veterinary medicine, driven by the inappropriate use of antimicrobials. Companion animals may act as community reservoirs and sentinels for antimicrobial‐resistant bacteria due to their close contact with humans and other animals.

Colistin Resistance Mechanisms in Klebsiella pneumoniae Strains from Taiwan

, 2017
Colistin is one of the antibiotics of last resort for the treatment of carbapenem-resistant Klebsiella pneumoniae infection. This study showed that capsular type K64 (50%) and ST11 (53.9%) are the prevalent capsular and sequence types in the colistin ...
