    [Abstract]

    Bacterial swarming refers to a rapid spread, with coordinated motion, of flagellated bacteria on a semi-solid surface (Harshey, 2003). There has been extensive study on this particular mode of motility because of its interesting biological and physical relevance, e.g., enhanced antibiotic resistance (Kearns, 2010) and turbulent collective motion

    Intrathoracic Inoculation of Zika Virus in Aedes aegypti

    [Abstract]

    Aedes aegypti mosquitoes are the main vectors of many medically relevant arthropod-borne (arbo) viruses, including Zika (ZIKV), dengue (DENV), and yellow fever (YFV). Vector competence studies with Ae. aegypti often involve challenging mosquitoes with an artificial bloodmeal containing virus and later quantifying viral titer or infectious

    Microscopic Detection of ASC Inflammasomes in Bone Marrow Derived Macrophages Post Stimulation
    刺激后骨髓源性巨噬细胞中ASC炎症小体的显微检测

    [Abstract]

    An inflammasome is an intracellular multiprotein complex that plays important roles in host defense and inflammatory responses. Inflammasomes are typically composed of the adaptor protein apoptosis-associated speck-like protein containing a CARD (ASC), cytoplasmic sensor protein, and the effector protein pro-caspase-1. ASC assembly into a protein

    Tomato Stem Injection for the Precise Assessment of Ralstonia solanacearum Fitness in Planta
    番茄茎杆注射法精确评价青枯菌在植物中的适应性
    作者:Yaru Wang, Liu Xian, Gang Yu and Alberto P. Macho日期:08/20/2021,浏览量:480,Q&A: 0
    [Abstract]

    Ralstonia solanacearum is a soil-borne pathogen with worldwide distribution that causes bacterial wilt disease in more than 250 plant species. R. solanacearum invades plants through the roots, reaches the vascular system, and colonizes the whole plant by moving through the xylem, where it eventually replicates rapidly, causing plant death. Usual

    Optimised Method for the Production and Titration of Lentiviral Vectors Pseudotyped with the SARS-CoV-2 Spike
    SARS-CoV-2刺突慢病毒伪型载体制备和滴定的优化方法
    [Abstract]

    The use of recombinant lentivirus pseudotyped with the coronavirus Spike protein of SARS-CoV-2 would circumvent the requirement of biosafety-level 3 (BSL-3) containment facilities for the handling of SARS-CoV-2 viruses. Herein, we describe a fast and reliable protocol for the transient production of lentiviruses pseudotyped with SARS-CoV-2 Spike

    Visualization of Host Cell Kinase Activation by Viral Proteins Using GFP Fluorescence Complementation and Immunofluorescence Microscopy
    利用GFP荧光互补和免疫荧光显微镜观察病毒蛋白对宿主细胞激酶的激活

    [Abstract]

    Non-receptor protein-tyrosine kinases regulate cellular responses to many external signals and are important drug discovery targets for cancer and infectious diseases. While many assays exist for the assessment of kinase activity in vitro, methods that report changes in tyrosine kinase activity in single cells have the potential to provide

    Tracking the Subcellular Localization of Surface Proteins in Staphylococcus aureus by Immunofluorescence Microscopy
    用免疫荧光显微镜追踪金黄色葡萄球菌表面蛋白的亚细胞定位
    作者:Salvatore J. Scaffidi, Mac A. Shebes and Wenqi Yu日期:05/20/2021,浏览量:3356,Q&A: 0
    [Abstract]

    Surface proteins of Staphylococcus aureus and other Gram-positive bacteria play essential roles in bacterial colonization and host-microbe interactions. Surface protein precursors containing a YSIRK/GXXS signal peptide are translocated across the septal membrane at mid-cell, anchored to the cell wall peptidoglycan at the cross-wall compartment,

    Parasitemia Evaluation in Mice Infected with Schistosoma mansoni
    曼氏血吸虫感染小鼠的寄生虫病评估
    作者:Naiara Clemente Tavares and Marina Moraes Mourão日期:05/20/2021,浏览量:2186,Q&A: 0
    [Abstract]

    Schistosomiasis is a neglected tropical disease. Its treatment relies on the use of a single drug, praziquantel. Due to treatment limitations, an alternative for schistosomiasis chemotherapy is required; thus, a better understanding of parasite biology and host-parasite interactions is valuable to aid the identification of new anti-Schistosoma

    Assessing Swarming of Aerobic Bacteria from Human Fecal Matter
    人类粪便中需氧细菌群集的评估
    作者:Arjun S. Byju, Deeti Patel, Weijie Chen and Sridhar Mani日期:05/05/2021,浏览量:1560,Q&A: 0
    [Abstract]

    Swarming – swift movement across a surface via flagella propulsion – is a unique property of many bacteria. The role of swarming, particularly among bacterial populations of the human gut microbiome, is not yet fully understood; although, it is becoming an area of increased scientific and clinical inquiry. To further characterize

    Histological Methods to Detect Early-stage Plant Defense Responses during Artificial Inoculation of Lolium perenne with Epichloë festucae
    羊茅人工接种多年生黑麦草过程中植物早期防御反应的组织学检测

    [Abstract]

    Epichloë species form agriculturally important symbioses with many cool season grasses. To study these symbioses, such as the interaction of Epichloë festucae with perennial ryegrass (Lolium perenne), host plants can be infected by artificial inoculation of etiolated seedlings. This inoculation is performed by placing mycelium into an
