  2. Anti-biofilm effects of sinomenine against Staphylococcus aureus

    • Fri, 09/23/2022 - 04:00
    • Food Science and Biotechnology
    • Staphylococcus aureus is a gram-positive foodborne pathogen capable of forming strong biofilms. This study identified that anti-biofilm natural compound against S. aureus. Sinomenine, a natural compound, showed significantly reduced biofilm formation (31.97–39.86%), but no effect on bacterial growth was observed. The dispersion of preformed biofilms was observed by confocal laser scanning microscopy (CLSM).

    • The delayed treatment of pediatric periorbital cellulitis may have severe consequences. In addition, the antibiotic efficacy against causative bacteria may change over time, and it is important to understand the appropriate antibiotic options for effective treatment in pediatric patients. We compared the changes in cultured bacteria and drug susceptibility tests between two decades, 2010–2019 and 2000–2009, to establish antibiotics for empirical use.

    • Antibiotics
    • Biofilms are complex bacterial structures composed of bacterial cells embedded in extracellular polymeric substances (EPS) consisting of polysaccharides, proteins and lipids. As a result, biofilms are difficult to eradicate using both mechanical methods, i.e., scraping, and chemical methods such as disinfectants or antibiotics. Bacteriophages are shown to be able to act as anti-biofilm agents, with the ability to penetrate through the matrix and reach the bacterial cells.
