International Journal of Food Science &Technology, Accepted Article. Developing rapid detection tools and methods for foodborne pathogens has always been a research hotspot, which is undoubtedly very important for food safety. In this study, the preparation of functional magnetic nanoprobes and their application to detect target pathogens in a complex matrix by low-field nuclear magnetic resonance (LF-NMR) is demonstrated.

In the present research, in order to screen out the best candidates from 12 different EOCs, we proposed three in vivo screening methods, namely the screening method of bioluminescence of V. campbellii associated with brine shrimp, regrowth performance of V. campbellii, and immune gene expression of brine shrimp without challenge. Our result showed that challenged with V.

Aspergillus westerdijkiae is an ochratoxin A (OTA) producer mould in dry-cured meat products.

Whole genome sequencing (WGS) of foodborne pathogens such as Listeria monocytogenes is globally on the rise in the food industry.

Aflatoxins are the secondary metabolites produced by Aspergillus flavus and Aspergillus parasiticus and have severe pathological effects on the health of human and animals. The present study was designed to investigate the toxicopathological changes induced by aflatoxins and mitigative potential of Lactobacillus plantarum in broiler birds.

Medicinal plants are important in the South African traditional healthcare system, the growth in the consumption has led to increase in trade through muthi shops and street vendors. Medicinal plants are prone to contamination with fungi and their mycotoxins.

Flour samples spiked with ochratoxin A (OTA) (3,10 and 20 μg kg–1), zearalenone (ZEA) (75, 100, and 200 μg kg–1), and deoxynivalenol (DON) (500, 750, and 1000 μg kg–1), and combined mycotoxins (OTA, ZEA and DON at 20,

The objectives of this study were to determine the prevalence of Listeria monocytogenes in ready-to-eat (RTE) foods, and the growth boundaries of two strains of L. monocytogenes isolated from RTE foods and one ATCC7644 strain under different temperature (4, 20, and 37°C), salt (0, 1, 2, 3, and 4% w/v), and nisin (0, 50, 100, 200, and 400 µg/mL) levels with different inoculum sizes (3, 4, 5, and 6 log10 CFU/mL).

The increasingly serious pollution of microplastics and heavy metals is likely to affect the efficacy of flavonoids synthesized by dandelion in natural medicine fields.

Gliomas that are classified as grade II or grade III lesions by the World Health Organization (WHO) are highly aggressive, and some may develop into glioblastomas within a short period, thus portending the conferral of a poor prognosis for patients. Previous studies have implicated basement membrane (BM)-related genes in glioma development. In this study, we constructed a prognostic model for WHO grade II/III gliomas in accordance with the risk scores of BM-related genes.

Polyethylenimines (PEIs), a group of polycationic molecules, are known to impair the outer membrane of Gram-negative bacteria and exhibit antimicrobial activity. The outer membrane of Gram-negative strains hinders the uptake of photosensitizer chlorophyllin. In this study, we report chlorophyllin and branched PEI combinations’ activity against Escherichia coli strains DH5α and RB791, Salmonella enterica sv. Typhimurium LT2, and Bacillus subtilis 168.

Population-based studies of Staphylococcus aureus contribute to understanding the epidemiology of S. aureus infection. We enrolled surgical inpatients admitted to an African tertiary-care hospital in order to prospectively analyze the nosocomial impact of S. aureus. Data collection included an active sampling of the anterior nares and infectious foci within 48 h after admission and subsequently when clinically indicated.

EFSA Journal, Volume 20, Issue 10, October 2022. EFSA established cumulative assessment groups and conducted retrospective cumulative risk assessments for two types of craniofacial alterations (alterations due to abnormal skeletal development, head soft tissue alterations and brain neural tube defects) for 14 European populations of women in childbearing age.

Cryptosporidium spp. are common enteric parasites in humans and animals. Herein, 175 faecal specimens were collected from a broiler farm in Xinjiang, China, including seven repeated samplings at 10-day intervals of broilers aged 10 to 70 days. Cryptosporidium was detected and identified by PCR–RFLP analysis.

Foodborne infections caused by Salmonella have been linked to a variety of poultry products. The aim of this study was to compare the molecular profile of virulence genes considering different serotypes of Salmonella, isolates were from chicken breast sampled during the last two decades (1999 to 2010 and 2011 to 2018).

It was investigated the microbial protection of corn tortilla, traditional Mexican food with high acceptance, for food safety.

Some water disinfection treatments, such as chlorine and chlorine dioxide, used in the fresh-cut industry to maintain the microbiological quality of process water (PW), inactivate bacterial cells in the water but they also lead to the induction of an intermediate state between viable and non-viable known as viable but non-culturable (VBNC) state.

In this study, the antibacterial effects of benzyl isothiocyanate (BITC) against Vibrio parahaemolyticus (V. parahaemolyticus) were investigated at the protein level using label-free quantitative proteomic analysis. The results showed that 243 differentially expressed proteins were induced by BITC at 10 μmol/L in V. parahaemolyticus.

Staphylococcus aureus is responsible for severe skin and respiratory infections and food poisoning, resulting in hospitalizations and high morbidity worldwide.

Cadmium (Cd) toxicity not only affects plant growth and development, but also affects human health through the food chain. Several studies have demonstrated that Selenium (Se) alleviates Cd stress in plants; however, whether and how Se-alleviated Cd stress by regulating the structure of soil microbial community remain largely unclear.

Climate warming may affect the performance of plants directly through altering vegetative or reproductive traits, and indirectly through modifying interactions with their pollinators. On the other hand, the addition of fertilizers to the soil may increase the quantity and quality of floral rewards, favoring the visitation of pollinators and, consequently, the reproductive success of plants.

Cereals and cereal-based products are primary sources of nutrition across the world. However, contamination of these foods with aflatoxins (AFs), secondary metabolites produced by several fungal species, has raised serious concerns. AF generation in innate substrates is influenced by several parameters, including the substrate type, fungus species, moisture content, minerals, humidity, temperature, and physical injury to the kernels.

Background:Toxoplasma gondii is an obligate intracellular parasite that invades nearly all nucleated cells of a broad spectrum of vertebrate hosts, and which may cause serious disease in immunocompromised patients, as well as in the immunologically incompetent fetus. This study aimed to establish a loop-mediated isothermal amplification (LAMP) technique to rapidly detect T. gondii in the blood infection by targeting the 529 bp repeat element of T. gondii.

mBio, Ahead of Print. Toxoplasma gondii is an intracellular apicomplexan parasite that relies on cyclic GMP (cGMP)-dependent signaling to trigger timely egress from host cells in response to extrinsic and intrinsic signals. A guanylate cyclase (GC) complex, conserved across the Apicomplexa, plays a pivotal role in integrating these signals, such as the key lipid mediator phosphatidic acid and changes in pH and ionic composition.

Journal of Food Biochemistry, EarlyView. Black ginseng (BG) shows beneficial effects on liver injury, but the related mechanism has not been fully revealed. This study attempted to investigate the protective effects and associated mechanisms of BG against nonalcoholic steatohepatitis (NASH). Twelve ginsenosides in BG were annotated by ultrahigh performance liquid chromatography combined with high resolution mass spectrometry (UHPLC-HRMS).
