  1. LmTraceMap: A Listeria monocytogenes fast-tracing platform for global surveillance

    • Tue, 05/10/2022 - 04:00
    • PLOS ONE
    • by Yen-Yi Liu, Chih-Chieh Chen, Chien-Hua Yang, Hui-Yi Hsieh, Jia-Xin He, Hao-Hsuan Lin, Chi-Ching Lee Listeria monocytogenes can cause listeriosis, and people with hypoimmunity such as pregnant women, infants and fetuses are at high risk of invasive infection. Although the incidence of listeriosis is low, the fatality rate is high. Therefore, continual surveillance and rapid epidemiological investigation are crucial for addressing L. monocytogenes.

  2. Centrifugally spun micro-nanofibers based on lemon peel oil/gelatin as novel edible active food packaging: Fabrication, characterization, and application to prevent foodborne pathogens E. coli and S. aureus in cheese

    • Tue, 05/10/2022 - 04:00
    • Food Control
    • This study aimed to develop innovative micro-nano fibers loaded with lemon peel essential oil for food packaging via centrifugal spinning. Lemon peel essential oil (LPO) was extracted from dried lemon peel by hydrodistillation. The major one of the 16 components of the extract detected by GS-MS was limonene (60.4%). Gelatin fibrous mats loaded with three different concentrations of LPO were fabricated with centrifugal spinning and then cross-linked.

  3. Physiological and Transcriptomic Comparison of Two Sunflower (Helianthus annuus L.) Cultivars With High/Low Cadmium Accumulation

    • Mon, 05/09/2022 - 04:00
    • Frontiers in Plant Science
    • The toxic heavy metal cadmium (Cd) is easily absorbed and accumulated in crops and affects human health through the food chains. Sunflower (Helianthus annuus L.) is a globally important oil crop. In this study, two sunflower cultivars 62\3 (high Cd) and JB231AC (low Cd), were chosen to compare physiological and transcriptomic responses at different Cd concentrations (0, 25, 50, and 100 μM). The results showed that JB231AC had better Cd tolerance than 62\3.

  4. Proteomic Analysis Revealed Metabolic Inhibition and Elongation Factor Tu Deamidation by p-Coumaric Acid in Cronobacter sakazakii

    • Mon, 05/09/2022 - 04:00
    • Frontiers in Microbiology
    • Screening drugs and compounds to fight against Cronobacter sakazakii (C. sakazakii), one of the most common pathogens that can cause fatal necrotizing enterocolitis, septicema and meningitis, is still needed. We found that p-coumaric acid (pCA) has an inhibitory effect on C. sakazakii in vitro and in vivo. Proteomic changes of C. sakazakii BAA-894 exposed to pCA were studied to reveal the antibacterial mechanisms involved. A total of 1,553 proteins were identified in C.

    • Mon, 05/09/2022 - 04:00
    • Frontiers in Microbiology
    • Acute hepatopancreatic necrosis disease (AHPND) is an emerging bacterial disease of cultured shrimp caused mainly by Vibrio parahaemolyticus, which harbors the lethal PirAB toxin genes. Although Penaeus vannamei (P. vannamei) postlarvae are susceptible to AHPND, the changes in the bacterial communities through the larval stages affected by the disease are unknown. We characterized, through high-throughput sequencing, the microbiome of P.

  6. Evaluation and Optimization of Microdrop Digital PCR for Detection of Serotype A and B Clostridium botulinum

    • Mon, 05/09/2022 - 04:00
    • Frontiers in Microbiology
    • Clostridium botulinum is the causative pathogen of botulism. Laboratory detection of C. botulinum is essential for clinical therapy treatment of botulism due to the difficulty in diagnosis, especially in infant botulism. The extreme toxicity of botulinum neurotoxin (BoNT) requires a sensitive detection method. Due to the detection limit of real-time quantitative PCR (q-PCR), a more sensitive detection method, micro-drop digital PCR (ddPCR) was applied in C. botulinum main serotypes A and B.

    • Mon, 05/09/2022 - 04:00
    • Genes
    • The buffalo is an amazing ruminant. Its ability to degrade lignin, which has been recently reported, is most likely due to unique rumen microorganisms with lignin-degradation potential. Our goal was to explore the lignin-degradation potential of ruminal microorganisms, in which ligninolytic enzyme encoding genes were involved to provide ideas for revealing the mechanism of lignin degradation by buffalo.

    • Introduction

      Neisseria gonorrhoeae is a major concern of public health due to its extraordinary capacity to develop and acquire resistance to different antimicrobials used to treat gonorrhoea. Limited treatment options and uncontrolled transmission have raised the need to assess the antimicrobial susceptibility profile of the isolates and to establish affordable alternatives for laboratory diagnosis.

    • The intestinal microbiota plays important roles in animal health and growth. We investigated the efficacy and mechanisms of fecal microbiota transplantation (FMT) from adult SPF chickens against Salmonella Enteritidis (SE) infection in chicks. We transplanted 160 recipient SPF chicks (1-day-old) that were randomly divided into four groups, Ca (challenge), Cb (non-challenge), Fa (FMT and challenge) and Fb (FMT without challenge). The experiment lasted 40 days.
