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

Small, EarlyView.
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.

Programmable 3D Microfluidics Reveals Motility‐Driven Antibiotic Resistance Evolution in Gradients

Small, EarlyView.
Using a programmable microfluidic platform, this study shows that bacterial motility is crucial for resistance development in heterogeneous antibiotic landscapes. Motile Escherichia coli randomly migrates along antibiotic gradients, and sufficient movement is required for resistance to emerge.

Filtration‐Based SERS With In Situ Gold Growth in Bacterial Microenvironment for Rapid Detection of Low‐Level Bacteria

Small Methods, EarlyView.
A filtration‐assisted SERS platform integrating in situ gold growth within the bacterial microenvironment enables rapid and highly sensitive detection of low‐level bacteria in complex biological matrices. By overcoming hotspot–bacteria mismatch, the platform simultaneously achieves selective bacterial identification and rapid antimicrobial ...

Isolation of carbapenem‐resistant Pseudomonas aeruginosa and other Gram‐negative ESKAPE organisms from samples of raw‐meat diets for dogs in the UK

Veterinary Record, EarlyView.
Abstract Background Gram‐negative ESKAPE organisms are an emerging threat in veterinary medicine that also have zoonotic potential. However, little is known about the prevalence and risks of these organisms in pet food. We present the incidental finding of gram‐negative ESKAPE organisms within samples of raw meat diets for dogs in the United Kingdom ...

Mycobacterial Aminoglycoside Acetyltransferases: A Little of Drug Resistance, and a Lot of Other Roles

Frontiers in Microbiology, 2019
Aminoglycoside acetyltransferases are important determinants of resistance to aminoglycoside antibiotics in most bacterial genera. In mycobacteria, however, aminoglycoside acetyltransferases contribute only partially to aminoglycoside susceptibility ...

Clinical Features and Outcomes of Chronic Otitis Media Complications: A 20‐Year Retrospective Study at a Tertiary Hospital

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Objective Chronic otitis media (COM) is a major public health concern, particularly in developing countries. Although complications have decreased with modern antibiotics, they still cause significant morbidity and mortality. This study analyzed the clinical features, bacteriological profiles, and treatment outcomes of COM complications at a ...

Evolutionary and Epidemiological Characterization of Multidrug‐Resistant Escherichia coli Isolated From Pangolins in China

Integrative Zoology, EarlyView.
ABSTRACT Malayan pangolin populations have fallen to a critically endangered level, and illegal trafficking of wild pangolins is a global problem. Little is known about antimicrobial‐resistant bacteria (MDRB) harbored by pangolins, although pangolins are frequently consumed as food or used in traditional medicine. In this study, we report for the first

Contribution of RaeB, a Putative RND-Type Transporter to Aminoglycoside and Detergent Resistance in Riemerella anatipestifer

Frontiers in Microbiology, 2017
Riemerella anatipestifer is an important pathogenic bacterium that infects ducks. It exhibits resistance to multiple classes of antibiotics. Multidrug efflux pumps play a major role as a mechanism of antimicrobial resistance in Gram-negative pathogens ...

Spatial Patterns and Associated Factors of Intestinal Antibiotic Resistance Genes in Farmed Bullfrogs From Selected Farms Across Major Production Regions in China

Integrative Zoology, EarlyView.
Across selected bullfrog farms in major Chinese production regions, 106 intestinal ARG subtypes were detected, with tetracycline and sulfonamide resistance genes predominating and clear farm‐level variation. High‐risk ARGs, including ermB, floR, and qnrA, were associated with heavy metals, MGEs, and opportunistic pathogens. These findings highlight the
