The inhibitory effect of tea-polyphenol against common pathogenic bacteria was studied in this paper, and the minimum inhibitory concentration of tea-polyphenol against these pathogenetic bacteria was also determined. The results showed that the inhibitory effects of tea-polyphenol against Staphylococcus aureus, Bacillus cereus and Bacillus subtilis were all significantly strong, of which the inhibition zone were significant; the inhibitory effects of tea-polyphenol against proteus and salmonella were weak, of which the inhibition zone were blur; the inhibitory effect of tea-polyphenol against...
