Screening for novel quorum-sensing inhibitors to interfere with the formation of Pseudomonas aeruginosa biofilm.
J. Med. Microbiol. 60(Pt 12) , 1827-34, (2011) The objective of this study was to screen for novel quorum-sensing inhibitors (QSIs) from traditional Chinese medicines (TCMs) that inhibit bacterial biofilm formation. Six of 46 active components found in TCMs were identified as putative QSIs based on molecu... |
