Optimization of Dual‐Bacteriophage Magnetic Nanoprobe for the Detection of Staphylococcus aureus and Pseudomonas aeruginosa

Macromolecular Bioscience, Volume 26, Issue 8, August 2026.
The optimal densities of two bacteriophages on magnetic nanoparticles are determined in order to make magnetic nanoprobes. These nanoprobes can bind bacteria in 10 min and be quickly retrieved from aqueous samples for later analysis. The nanoprobes are capable of capturing Staphylococcus aureus and Pseudomonas aeruginosa with concentrations as low as ...

Water Soluble‐Nitrogenous Secondary Metabolites From Talaromyces annesophieae MD2 Exhibit Anti‐Bacterial, Anti‐Cancer, Anti‐Oxidant, and Cytoprotective Activities

MicrobiologyOpen, Volume 15, Issue 4, August 2026.
The dichloromethane extract (DCM‐E) was prepared from the culture supernatant of the fungus Talaromyces annesophieae MD2 was fractionated using chromatographic techniques. The subfraction 3 was determined to contain four major nitrogenous compounds and exhibit antibacterial, anticancer, antioxidant, and cytoprotective activities.

Microarray analysis ofEscherichia coliO157:H7

World Journal of Gastroenterology, 2005
To establish the rapid, specific, and sensitive method for detecting O157:H7 with DNA microchips.Specific oligonucleotide probes (26-28 nt) of bacterial antigenic and virulent genes of E. coli O157:H7 and other related pathogen genes were pre-synthesized and immobilized on a solid support to make microchips. The four genes encoding O157 somatic antigen

Detection of Escherichia coli O157:H7 by multiplex PCR [PDF]

Journal of Clinical Microbiology, 1995
In order to develop a PCR assay for Escherichia coli O157:H7, a portion of the 60-MDa plasmid harbored by enterohemorrhagic E. coli (EHEC) was sequenced and PCR primers were designed. A multiplex PCR method was then designed by employing primers specific for the EHEC eaeA gene, conserved sequences of Shiga-like toxins I (SLT-I) and II (SLT-II), and the

Characterization and Removal of Multispecies Biofilms Formed by L. monocytogenes, S. aureus, and E. coli

Journal of Food Safety, Volume 46, Issue 4, August 2026.
The formation of mono‐, dual‐, and triple‐species biofilms by L. monocytogenes, S. aureus, and E. coli was characterized by cell growth, metabolic activity, staining, and microscopy. Their resistance to a commercial disinfectant (NaOCl) and natural agents such as vinegar and lactic acid was evaluated.

Control of Escherichia coli O157:H7 with Sodium Metasilicate

Journal of Food Protection, 2004
Three intervention strategies-trisodium phosphate, lactic acid, and sodium metasilicate--were examined for their in vitro antimicrobial activities in water at room temperature against a three-strain cocktail of Escherichia coli O157:H7 and a three-strain cocktail of "generic" E. coli. Both initial inhibition and recovery of injured cells were monitored.

Membrane Perturbation and Nutrient Transport Dysregulation Are Conserved Targets of Thyme Essential Oil Against Shiga Toxin‐Producing Escherichia coli on Pea Sprouts

Food Frontiers, Volume 7, Issue 4, July 2026.
ABSTRACT Vegetable sprouts are high‐risk carriers of Shiga toxin‐producing Escherichia coli (STEC), with the emerging “big six” STEC serogroups (e.g., O26, O45, O103, O111, O121, and O145) posing growing threats. Thyme essential oil (EO) is a promising natural sanitizer; however, its effects against different STEC strains remain unclear.

Thermal Destruction of Escherichia coli O157:H7 in Hamburger

Journal of Food Protection, 1997
The inactivation of E. coli O157:H7 in ground beef patties cooked in a skillet was investigated. Ground beef patties inoculated with a mixture of five strains of E. coli O157:H7 were cooked in a Farberware skillet set at a temperature of 275°F (137°C).

Food Safety and Nutritional Aspects of Plant‐Based Dairy and Meat Alternatives: A Review

Food Science &Nutrition, Volume 14, Issue 7, July 2026.
Plant‐based dairy and meat alternatives (PBDA and PBMA) offer sustainability benefits but also introduce chemical and microbiological hazards to the diet. Key concerns include emerging mycotoxins, heavy metals, process contaminants, and heat‐resistant spore‐forming bacteria.

Survival of Enterohemorrhagic Escherichia coli O157:H7 in Water

Journal of Food Protection, 1998
Several recent Escherichia coli O157:H7 outbreaks associated with both drinking and recreational water raise concerns about waterborne illness caused by this pathogen. The survival characteristics of a mixture of five nalidixic acid-resistant E. coli O157:H7 strains (10(3) CFU/ml) in filtered and autoclaved municipal water, in reservoir water, and in ...
