We examined tea extracts, (-) epigallocatechin gallate (EGCg) and theaflavin digallate (TF3) fortheir antimicrobial and microbicidal activities against <I>Mycoplasma</I>. Green tea and black tea showedantimicrobial activities against <I>M. pneumoniae</I>. At a concentration of 0.2% green tea and black teashowed microbicidal activities against <I>M. pneumoniae</I> and <I>M. orale</I> but not against <I>M. salivarium</I>.Extracts of pu-erh tea showed a slight microbicidal activity against <I>M. pneumoniae</I> and <I>M. orale</I>.EGCg purified from green tea and TF3 from black tea markedly showed microbicidal activities against<I>M. pneumoniae</I>. <I>M. orale</I> and <I>M. salivarium</I>. These results suggest that tea and catechins can be usedas prophylactic agents against <I>Mycoplasma pneumoniae</I> infection.
