The anti-bacterial effects of green tea catechins (GTCs) have been extensively studied. (-)-Epigallocatechin-3-O-gallate (EGCG), the most abundant in GTCs, has shown the highest anti-microbial effect among GTCs. This review focuses on anti-bacterial effects and veterinary use of GTCs and EGCG. EGCG shows inhibition of bacterial growth and bio-film formation, and bactericidal effect, resulting from stress response and damage of cell membrane. In veterinary use, feed addition of EGCG and TE brought health improvement to livestock.
