    [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

    [Abstract]

    Throughout their life cycle, bacteria shed portions of their outermost membrane comprised of proteins, lipids, and a diversity of other biomolecules. These biological nanoparticles have been shown to have a range of highly diverse biological activities, including pathogenesis, community regulation, and cellular defense (among others). In recent

    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

    [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

    [Abstract]

    Odor-detecting olfactory sensory neurons residing in the nasal olfactory epithelium (OE) are the only neurons in direct contact with the external environment. As a result, these neurons are subjected to chemical, physical, and infectious insults, which may be the underlying reason why neurogenesis occurs in the OE of adult mammals. This feature

    Screening for Lysogen Activity in Therapeutically Relevant Bacteriophages
    筛选与治疗相关的噬菌体的溶原活性

    [Abstract]

    Lysogenic phages can integrate into their bacterial host’s genome, potentially transferring any genetic information they possess including virulence or resistance genes, and are therefore routinely excluded from therapeutic applications. Lysogenic behavior is typically seen in phages that create turbid plaques or possess subpar bactericidal

    Candida Biofilm Formation Assay on Essential Oil Coated Silicone Rubber
    精油包覆硅橡胶上念珠菌生物膜形成的实验研究
    [Abstract]

    Development of biofilm associated candidemia for patients with implanted biomaterials causes an urgency to develop antimicrobial and biofilm inhibitive coatings in the management of recalcitrant Candida infections. Recently, there is an increase in the number of patients with biofilm formation and resistance to antifungal therapy. Therefore, there
