Susceptibility of Porphyromonas gingivalis and Streptococcus mutans to Antibacterial Effect from Mammea americana
Figure 1
Bacterial sensitivity assays of Mammea americana extract. (a) Sensitivity of Porphyromonas gingivalis (ATCC 33277) to oily and ethanolic phases; exposure of P. gingivalis to mamey extract inhibited bacterial growth by approximately 96%. (b) Sensitivity of Streptococcus mutans (ATCC 25175) to mamey extract; the two phases inhibited bacterial growth by approximately 31.5%. Each symbol represents the mean for the group ( per group); inoculum: (●), oily phase (500 μg/mL): (■), ethanolic phase (500 μg/mL): (▲), control (gentamicin (16 μg/mL)): (◆), and value < 0.05: (*); Kruskal-Wallis test and Dunnett’s posttest.
