Listeria monocytogenes (L. monocytogenes) is a well-known food-borne pathogen that causes systemic listeriosis. Its biofilm-forming ability is known to be important for its antimicrobial resistance and persistence. Epigallocatechin-gallate (EGCG) is the highest component of tea polyphenols in tea extracts and has broad-spectrum antimicrobial activities. In this study, the efficacys of EGCG to inhibit biofilm formation and hemolytic activity of L. monocytogenes were determined. EGCG at 20 mu g/mL, 40 mu g/mL (less than compound's minimum inhibitory concentration, MIC) and 200 mu g/mL (1 MIC) we...
