Table 4 a. Measures of the growth inhibition diameter induced by the three extracts alone, or in combination with Ampicillin and Amoxicillin (one representative experiment, out of three, as shown in Fig. 6a, Antibiotic plus extracts; b. comparison of inhibiting (few CFU) and bactericidal (no CFU) effects by plating the agar inside the inhibition zone after 24 h (see also figure S2b).
