Item Metadata only Volatile anesthetic isoflurane exposure facilitates Enterococcus biofilm infection(2023-10-01) Maisat W.; Yuki K.; Mahidol UniversityEnterococcus faecalis (E. faecalis) is one of the major pathogenic bacteria responsible for surgical site infections. Biofilm infections are major hospital-acquired infections. Previous studies suggested that ions could regulate biofilm formation... in microbes. Volatile anesthetics, frequently administered in surgical setting, target ion channels. Here, we investigated the role of ion channels/transporters and volatile anesthetics in the biofilm formation by E. faecalis MMH594 strain and its ionPublication Metadata only A novel bacteriocin from Enterococcus faecalis 478 exhibits a potent activity against vancomycin-resistant enterococci(2017-10-01) Uraporn Phumisantiphong; Kanokrat Siripanichgon; Onrapak Reamtong; Pornphan Diraphat; Mahidol Universitywas to discover and characterize bacteriocin against clinical isolates of MDRE and VRE. Over 10,000 bacterial isolates from water, environment and clinical samples were screened. E. faecalis strain 478 isolated from human feces produced the highest antibacterial... activity against several MDRE and VRE strains. The optimum condition for bacteriocin production was cultivation in MRS broth at 37°C, pH 5–6 for 16 hours. The bacteriocin-like substance produced from E. faecalis strain EF478 was stable at 60°C for at leastPublication Metadata only Comparative persistence of human sewage-specific enterococcal bacteriophages in freshwater and seawater(2018-07-01) Namfon Booncharoen; Skorn Mongkolsuk; Kwanrawee Sirikanchana; Chulabhorn Research Institute; Thailand Ministry of Education; Mahidol University; Chulabhorn Royal Academy© 2018, Springer-Verlag GmbH Germany, part of Springer Nature. Enterococcus faecalis bacteria have been recently reported for their ability to host bacteriophages that are specifically from human sewage, suggesting their application to track human... the Thailand-isolated E. faecalis strains AIM06 and SR14 exhibited morphologies consistent with the Siphoviridae, Podoviridae, and Myoviridae families. Four representative bacteriophages were separately spiked into environmental water samples (n = 7) comprisingItem Metadata only Aptamer-Based Label-Free Colorimetric Assay Using Gold Nanoparticles for Specific Detection of Streptococcus suis(2026-04-01) Sangboonruang S.; Semakul N.; Matchawong A.; Sattaphan A.; Saengsawang K.; Srisawat C.; Tragoolpua K.; Tharinjaroen C.S.; Sangboonruang S.; Mahidol UniversityStaphylococcus aureus, S. pneumoniae, S. pyogenes, Pseudomonas aeruginosa, Escherichia coli, Enterococcus faecium, and E. faecalis, was not present, indicating the specificity of this assay. Moreover, the aptasensor exhibited high sensitivity with a limit
