We found that extracts of Japanese green tea leaves inhibited the growth of various bacteria causing diarrheal diseases. All tea samples tested showed antibacterial activity against <i>Staphylococcus aureus, S. epidermidis, Vibrio cholerae</i> O1, <i>V. cholerae</i> non O1. <i>V. parahaemolyticus, V. mimicus, Campylobacter jejuni</i> and <i>Plesiomonas shigelloides</i>. None of the tea samples had any effect on the growth of <i>V. fluvialis, Aeromonas sobria, A. hydrophila, Pseudomonas aeruginosa, Salmonella enteritidis, enteroinvasive Escherichia coli</i>, enterohemorrhagic <i>E. coli</i>, enteropathogenic <i>E. coli</i>, enterotoxigenic <i>E. coli, Enterobacter cloacae</i> or <i>Yersinia enterocolitica. Salmonella</i> and <i>Shigella</i> showed susceptibilities different depending on the kind of Japanese green tea. Japanese green tea showed also bactericidal activity over <i>S. aureus</i>, <i>V. parahaemolyticus</i> and even enteropathogenic <i>E. coli</i> which was not sensitive when tested by cup method. The bactericidal activity was shown even at the drinking concentration in daily life.
