High resolution meltcurve PCR assay for detection of salmonella and escherichia coli O157:H7 in foods
Foodborne illnesses associated with Salmonella and Escherichia coli O157:H7 have become world-wide public-health problems. Conventional methods for the identification of foodborne pathogens are tedious, expensive, and time-consuming. Alternatively, real-time PCR (RT-PCR) as a promising method to …

Minimum Ultraviolet Light Dose Determination and Characterization of Stress Responses that Affect Dose for Listeria monocytogenes Suspended in Distilled Water, Fresh Brine, and Spent Brine
Foodborne illnesses caused by Listeria monocytogenes have long been associated with ready-to-eat (RTE) meats contaminated after the primary thermal process has been applied. It is believed that brine solutions used to chill cooked RTE products may serve as a reservoir for L. monocytogenes becoming …

Investigating the effect of mutations in lipopolysaccharides (LPS) (O-antigen and Core region) of Salmonella Typhimurium on the colonisation of “microgreens”
In recent years, foodborne illnesses linked to the consumption of raw leafy greens, particularly microgreens, have significantly increased. Salmonella Typhimurium, a common foodborne pathogen, has been implicated in several outbreaks, underscoring the importance of understanding its interactions …

Molecular analysis of GerP and spore-associated proteins of Bacillus cereus
… are the causative agents of emetic and diarrheal foodborne illnesses. Typically, spores will survive thermal treatments that destroy vegetative cells, and then go on to germinate to form the vegetative cells that are associated with toxin production. The spore has to germinate in order to develop …
