  1. Antagonism of Cyanamide-3-O-glucoside and protocatechuic acid on Aflatoxin B1-induced toxicity in zebrafish larva (Danio rerio)

    • Toxicon
    • The zebrafish model was used to evaluate the antioxidant properties of cyanidin-3-O-glucoside (C3G) and its metabolite protocatechuic acid (PCA) against aflatoxin B1 (AFB1)-induced hepatotoxicity and oxidative stress. In this study, zebrafish larvae were cultured for 3 days post fertilization (dpf) and then induced with AFB1. After induced 4 h, 8 h, 12 h, and 24 h, 5 μg/mL C3G/PCA was added and then co-cultured to 5 dpf, respectively.

  2. High resolution parallel sequencing reveals multi-strain Campylobacter in broiler chicken flocks testing ‘negative’ by conventional culture methods: implications for control of Campylobacter infection.

    • Poultry Science
    • Contaminated chicken meat is a major source of human Campylobacteriosis and rates of infection remain high, despite efforts to limit the colonisation of broiler (meat) chicken flocks on farms. Using conventional testing methods of culture or qPCR, Campylobacter is typically detected amongst broiler flocks from 3 weeks of age, leading to the assumption that infection is introduced horizontally into chicken rearing houses at this time.

  3. Synthesis of nano-sized lead sulfide thin films from Avocado (Glycosmis cochinchinensis) Leaf extracts to empower pollution remediation

    • Scientific Reports
    • The translucent and nano-crystalline PbS films were equipped with the CBD techniques on metal substrates by the temperature of 90 °C through aqueous solutions of Lead Nitrate and Thiourea. The XRD phases verify the crystalline property of synthesized thin films that the shape falls in the cubic structures with favourite orientations. It revealed that the prepared material is cubic crystal oriented as (111), (110), (100) and (101) crystal planes.

  4. Effect of Fumonisin B1 on Proliferation and Apoptosis of Intestinal Porcine Epithelial Cells

    • Toxins
    • Fumonisin B1 (FB1), which is a mycotoxin produced by Fusarium moniliforme and Fusarium rotarum, has a number of toxic effects in animals. Moldy feed containing FB1 can damage the intestine. In this study, we used intestinal porcine epithelial cells (IPEC-J2) as an in vitro model to explore the effects of FB1 on cell cycle and apoptosis.

  5. Comparative Genomic Analysis Discloses Differential Distribution of Antibiotic Resistance Determinants between Worldwide Strains of the Emergent ST213 Genotype of Salmonella Typhimurium

    • Antibiotics
    • Salmonella enterica constitutes a global public health concern as one of the main etiological agents of human gastroenteritis. The Typhimurium serotype is frequently isolated from human, animal, food, and environmental samples, with its sequence type 19 (ST19) being the most widely distributed around the world as well as the founder genotype.

  6. Association between Antibiotic Consumption and Resistance in Mink Production

    • Antibiotics
    • Antibiotic consumption is considered to be a main driver of antibiotic resistant bacteria. Mink breeding follows a distinctive seasonal reproduction cycle, and all of the mink produced in the northern hemisphere are bred, born, and pelted around the same time of year. Some of the diseases are age-related, which is reflected in the seasonal variation of antibiotic consumption.

    • Journal of Food Safety
    • Journal of Food Safety, EarlyView. High hydrostatic pressure (HHP) is a nonthermal processing technology that can maintain the original color, flavor and nutritional components of food during preservation. In this study, the mechanism of HHP to inactivate Escherichia coli O157:H7 was studied and clarified. Along with the increase of treatment pressure, the total number of viable bacteria decreased significantly (p < 0.05).

    • PLOS ONE
    • by Allison N. Hawkins, Sara J. Licea, Sierra A. Sleeper, Matthew C. Swearingen Calcium sulfate bone void filler beads are fully absorbable in the body, and are often used in complicated orthopedic infection cases to release a relatively high dose of antibiotics locally to the body site over time. However, the antibiotic resistance crisis and/or inability to treat chronic biofilm infections remains to be a formidable and increasing health threat.

  15. Monascus spp. and citrinin: Identification, selection of Monascus spp. isolates, occurrence, detection and reduction of citrinin during the fermentation of red fermented rice

    • International Journal of Food Microbiology
    • Red fermented rice (RFR) is rice fermented using Monascus spp. This product contains monacolin K, providing health benefits including mitigation of diarrhoea and improving blood circulation. RFR can produce pigments that can act as natural colour and flavouring agents. However, Monascus spp. (a fungal starter to ferment RFR) can also produce the mycotoxin, citrinin (CIT) which is believed to have adverse effects on human health.

  17. Campylobacter jejuni permeabilizes the host cell membrane by short chain lysophosphatidylethanolamines

    • Gut Microbes
    • Lysophospholipids (LPLs) are crucial for regulating epithelial integrity and homeostasis in eukaryotes, however the effects of LPLs produced by bacteria on host cells is largely unknown. The membrane of the human bacterial pathogen Campylobacter jejuni is rich in LPLs. Although C. jejuni possesses several virulence factors, it lacks traditional virulence factors like type III secretion systems, present in most enteropathogens.

  19. The RNA Polymerase Inhibitor Corallopyronin A Has a Lower Frequency of Resistance Than Rifampicin in Staphylococcus aureus

    • Antibiotics
    • Corallopyronin A (CorA) is active against Gram-positive bacteria and targets the switch region of RNA polymerase. Because of the high frequency of mutation (FoM) leading to rifampicin resistance, we determined the CorA FoM in S. aureus using fluctuation analysis at 4 &times; minimum inhibitory concentration (MIC). Resistant mutants were characterized. S. aureus strains HG001, Mu50, N315, and USA300 had an MIC of 0.25 mg/L.

    • Antibiotics
    • One of the most commonly used treatments for acute prosthetic joint infection (PJI) is DAIR (debridement, antibiotics and implant retention), which comprises the debridement and the retention of the implant, followed by antibiotic treatment. The efficacy of DAIR remains unclear, as the literature has demonstrated variable success rates, ranging from 26% to 92%.

    • Yersinia pestis, the causative agent of plague, is one of the most dangerous pathogens in the world. Both the cyclic AMP receptor protein (CRP) and ferric uptake regulator (Fur) are global regulators that control the expression of a great deal of genes involved in a variety of cellular functions in Y. pestis.

    • Fish & Shellfish Immunology
    • In invertebrates, several genes controlled by the Toll and immunodeficiency (IMD) signaling cascade are altered during microbial infection. However, little is known about the expression patterns of innate immune response genes in red-clawed crayfish (Cherax quadricarinatus). In the present study, the transcription of five genes was assessed in C. quadricarinatus challenged with Vibrio parahaemolyticus (V. parahaemolyticus).

  24. Detoxifying aflatoxin contaminated peanuts by high concentration of H2O2 at moderate temperature and catalase inactivation

    • Food Control
    • H2O2 treatment fulfills the requirement of environmentally friendly and safety concerns since it can be easily removed or decomposed into water and oxygen. Even though the high efficiency in detoxifying aflatoxins (AF) in foods by H2O2 was reported by some studies, the information to utilize this reagent for practical application is very limited. This study aimed at investigating the effect of 30 g/hg H2O2 at 50 °C on catalase-inactivated peanuts.

    • Food Control
    • The zearalenone (ZEN) lactonase from Gliocladium roseum (ZENG), possessing high activity but poor thermostability, is insufficient to meet the requirements of the feed industry. In this study, two potential hotspots, S162 and S220 in ZENG, were obtained through molecular dynamic (MD) simulations. In the first round, two mutants including S162P and S220R with increased thermostability were screened.
