The antibacterial effects of ultrasound (US) and cinnamon essential oil (CEO), individually and combined, were investigated against Listeria monocytogenes and Salmonella Typhimurium in low‐ and high‐fat milk during 6‐day storage. At the end of storage, CEO alone decreased 2 and 2.2 log cycles of Salmonella Typhimurium and 2.5 and 3 log cycles of L. monocytogenes populations in low‐ and high‐fat milk, respectively.

This work aimed to investigate the phytochemical composition, nutritional value, antioxidant, antihemolytic, antihyperglycemic, and antiproliferative activities of flaxleaf fleabane (Conyza bonariensis) leaves.

The aim of this study was to evaluate the probiotic potential and the viability in fermented oat dairy beverage of Lactobacillus curvatus isolate P99. Probiotic potential was assessed through the survival in simulated gastrointestinal tract conditions, autoaggregation, coaggregation, and hydrophobicity capacity and antimicrobial activity. The safety aspects of the isolate were evaluated for application in food, and these were determined by phenotypic and genotypic tests.

Three types of molecularly imprinted solid phase microextraction fibers were fabricated through sol‐gel method using diazinon, parathion‐methyl and isocarbophos as templates, respectively, and assembled together to construct a multifiber for analysis of organophosphorus pesticides in complex matrices. The multifiber provided large extraction capacity and high imprinting factor up to 3.89.

SUMMARY Non‐typhoidal Salmonella enterica (NTS) are diverse and important bacterial pathogens consisting of more than 2600 different serovars, with varying host‐specificity. Here, we characterized the poultry‐associated serovars in Israel, analyzed their resistome and illuminated the molecular mechanisms underlying common multidrug resistance (MDR) patterns.

Aims The identification and differentiation of antibiotic resistant bacteria by MALDI‐TOF‐MS profiling remains a challenge due to the difficulty in detecting unique protein biomarkers associated with this trait.

Aims To prevent the spread of brucellosis, a simple and rapid vertical flow technology for the detection of antibodies targeting brucellosis was developed. Methods and Results In this study, Brucella spp. lipopolysaccharide (LPS) was purified and used to detect brucellosis antibodies. Sheep IgG was used as a negative control. Colloidal gold‐labeled recombinant staphylococcus aureus protein A was sprayed on a fiberglass membrane to prepare an immunogold pads.

Ethylenediaminetetraacetic acid disodium salt (EDTA) was selected among various eluents due to its highest removal efficiency for lead (Pb) (43.7%) and zinc (Zn) (57.1%) leaching from Pb–Zn contaminated soil by soil column experiment. Compared with newly prepared EDTA eluent, using recycled EDTA eluent can still leaching down 71.1% of Pb and 63.2% of Zn respectively, which showed the reusable benefits of recycled EDTA eluent.

This study investigated the soil pollution level and evaluated the phytoremediation potential of 25 native plant species on a former gold mine-tailing site in Ghana. Plant shoots and associated soil samples were collected from a tailing deposition site and analyzed for total element concentration of As, Hg, Pb, and Cu.

Listeria monocytogenes is an important food-borne pathogen that is tolerant to many of the stresses commonly used during food preservation. Outside the host, the bacterium has a saprophytic lifestyle that includes periodic exposure to solar irradiance. The blue component of this light is known to influence the activity of the stress-inducible sigma factor Sigma B (σB). In this study, the influence of temperature and growth phase on the response of L.

Campylobacter jejuni is the leading cause of human foodborne enteritis worldwide. Poultry products are regarded as the main source of human campylobacteriosis. Strategies are being developed to reduce colonization of poultry by Campylobacter. The membrane transport protein CjaA was reported to stimulate mucosal immune responses, which can reduce the C. jejuni load in chickens. In this study, oral immunization of broilers with food-grade Lactococcus lactis NZ3900/pNZ8149 carrying the C.

The objective of this study was to evaluate the efficacy of simultaneous UV-A and UV-B irradiation (UV-A+B) for inactivating Escherichia coli O157:H7, Salmonella Typhimurium, and Listeria monocytogenes in both phosphate-buffered saline (PBS) and apple juice. A cocktail of the three pathogens was inoculated into PBS and apple juice, and then the suspensions were irradiated with UV lamps of 356 nm (UV-A) and 307 nm (UV-B).

Listeria monocytogenes is a hardy psychrotrophic pathogen that has been linked to several cheese-related outbreaks in the United States, including a recent outbreak in which a fresh cheese (queso fresco) was implicated. The purpose of this study was to develop primary, secondary, and tertiary predictive models for the growth of L. monocytogenes in queso fresco and to validate these models using nonisothermal time and temperature profiles. A mixture of five strains of L.

Due to the increasing number of studies reporting the detection of antimicrobial-resistant isolates of Listeria monocytogenes, we sought to determine the antimicrobial susceptibility of L. monocytogenes isolates collected in Italy and find potential correlations to their serotypes and multilocus sequence types (MLST). The antimicrobial susceptibility of 317 L.
