Susceptibility of Porphyromonas gingivalis and Streptococcus mutans to Antibacterial Effect from Mammea americana

Table 1

Minimum bactericidal concentration MBC from the oily and ethanolic phases against Streptococcus mutans and Porphyromonas gingivalis strains.

Bacterial strain	Phase	Results
Streptococcus mutans	Oily	Bactericidal activity from 500–125 µg/mL; lower concentrations were bacteriostatic.
	Ethanolic	Bactericidal activity from 500–250 μg/mL; lower concentrations were bacteriostatic.
Porphyromonas gingivalis	Oily	It showed bacteriostatic activity at all concentrations.
	Ethanolic	It showed bacteriostatic activity at all concentrations.
