Minimum inhibitory concentration and minimum bactericidal concentration of active subfraction FM2 and ciprofloxacin against three bacterial strains.

Fraction	Minimum inhibitory concentration (mg/mL) and minimum bactericidal concentration
	Shigella dysenteriae		Salmonella typhi		Escherichia coli (ATCC 25923)
	MIC	MBC	MIC.	MBC	MIC	MBC
FM2	0.62 ± 00	0.62 ± 00	1.25 ± 00^∗	1.25 ± 00^∗	1.25 ± 00^∗	1.25 ± 00^∗
