The MICs and susceptibility results are as follows: 99% were susceptible to the green tea extract at a concentration of ≤4.0 mg/ml (one strain was not susceptible at even 4.0 mg/ml); 94% were susceptible at ≤3.5 mg/ml; 76% were susceptible at ≤3.0 mg/ml; 40%, were susceptible at ≤2.5 mg/ml; The control strains varied; one being susceptible at ≤2.5 mg/ml and the other susceptible at ≤3.5 mg/ml. Table 2 shows the MIC results for the 79 strains that were susceptible at ≤4.0 mg/ml.
