Lipopolysaccharide‐Specific Aptasensor: A Spectroscopic Approach for Identifying Gram‐Negative Bacteria

open access: yesAnalytical Science Advances, Volume 7, Issue 2, December 2026.
We developed a novel aptasensor by integrating an anti‐lipopolysaccharide aptamer with a G‐quadruplex DNAzyme for the detection of Gram‐negative bacteria. This label‐free, spectroscopy‐based sensor detects E. coli with a limit of ∼2.7 × 105 cells/mL, providing a rapid, cost‐effective and specific method for identifying LPS‐containing bacteria ...

Bacteriological water quality in the Bay of Quinte

open access: yes, 1984
Data collected by the Ontario Ministry of the Environment (MOE) in 1981 and 1982, and by the local Health Unit in 1982, determined that Bay of Quinte waters in the vicinity of Trenton, Belleville, and Picton displayed zones of elevated fecal coliform (FC) levels as a result of unchlorinated urban discharges. These discharges appeared to be intermittent,

Parental Exposure to Nanoplastics and Graphene Oxide Induces Transgenerational Toxicity in Caenorhabditis elegans

open access: yesJournal of Applied Toxicology, Volume 46, Issue 12, Page 4826-4840, December 2026.
ABSTRACT Environmental pollution by emerging contaminants such as nanoplastics (NPs) and graphene oxide (GO) represents a growing threat to global health and ecosystems. This study investigated the effects of parental exposure, both isolated and combined, to 100 μg/L NPs (polystyrene, spherical, 100 nm) and 100 mg/L GO, using Caenorhabditis elegans as ...

Silent Contaminants: Antibiotic‐Resistant Bacteria in Food Systems

open access: yesMicrobiologyOpen, Volume 15, Issue 6, December 2026.
This graphical abstract illustrates the “farm‐to‐fork” cycle of antibiotic resistance, highlighting how antibiotic use promotes resistant bacteria that spread through animals, crops, food, and humans, emphasizing the interconnected nature of antimicrobial resistance and the need for integrated One Health strategies to mitigate its global impact ...

Prevalence and Molecular Epidemiology of Nontyphoidal Salmonella enterica Serovars Enteritidis and Typhimurium in Bushmeat Carcasses Sold in the Centre Region Markets, Cameroon

open access: yesMicrobiologyOpen, Volume 15, Issue 6, December 2026.
A total of 142 bushmeat samples were obtained from five localities in the Central Region of Cameroon and analyzed for the presence of Nontyphoidal Salmonella enterica, which showed a high prevalence, with Salmonella Enteritidis being the most frequently detected and exhibiting high genetic variation.

Charting the Voyages of Acinetobacter baumannii in Southeast Asia: Mapping the Regional Genomic Landscape

open access: yesMicrobiologyOpen, Volume 15, Issue 6, December 2026.
A genomic analysis of 853 Southeast Asian Acinetobacter baumannii isolates reveals the regional dominance of the highly resistant Global Clone 2 (GC2) lineage. Characterised by diverse mobile elements and distinct phage defenses, these findings establish a critical baseline to guide future surveillance and broader regional sampling.

Dissemination of Class 1, 2, and 3 Integrons Among Multidrug‐Resistant Isolates of Pseudomonas aeruginosa

open access: yesMicrobiologyOpen, Volume 15, Issue 6, December 2026.
Clinical Pseudomonas aeruginosa isolates showed widespread Class 1 and 2 integrons carrying diverse resistance‐associated gene cassettes, including aadB, blaOXA10‐aac(6′)‐II, and aadB‐blaOXA10‐aac(6′)‐Ib, which were strongly associated with antibiotic resistance phenotypes, highlighting the need for enhanced surveillance and targeted infection‐control ...

Endotoxins and Biological Implications—Review

open access: yesPublic Health Challenges, Volume 5, Issue 4, December 2026.
Graphical overview of endotoxin sources, exposure routes, biological effects, detection methods, and routes of elimination. ABSTRACT Endotoxins, also known as lipopolysaccharides (LPSs), are structural components of the outer membrane of Gram‐negative bacteria and some cyanobacteria.

Interspecific Cohabitation and Associated Zoonotic Risk in the Burrows of Niokolo‐Koba National Park, Senegal

open access: yesEcology and Evolution, Volume 16, Issue 11, November 2026.
Burrows concentrate multiple species in confined spaces, potentially facilitating pathogen transmission. Camera traps at 105 burrow entrances in Niokolo‐Koba National Park documented 32 species generating 172 interspecific cohabitations. Potential zoonotic bacteria (Treponema, Francisella) were detected, and ticks were found in half of sampled burrows,
