Phytochemical Screening, Toxic Effects, and Antimicrobial Activity Studies of Digitaria abyssinica (Hochst. ex A.Rich.) Stapf (Poaceae) Rhizome Extracts against Selected Uropathogenic Microorganisms

Table 4

Average MIC and MBC or MFC (mg/ml) of D. abyssinica extracts against selected uropathogenic microorganisms.

Test organism	Aqueous extract		Methanol extract		Dichloromethane : methanol extract
	MIC	MBC or MFC	MIC	MBC or MFC	MIC	MBC or MFC
Candida. albicans	31.25	62.5^MBC	31.25	62.5^MBC	62.5	125^MBC
Escherichia coli	>250	>250^MBC	>250	>250^MBC	>250	>250^MBC
Neisseria gonorrhoeae	>250	>250^MBC	>250	>250^MBC	>250	>250^MBC
Staphylococcus aureus	>250	>250^MFC	>250	>250^MFC	>250	>250^MFC

Key: MIC—minimum inhibitory concentration; MBC—minimum bactericidal concentration; MFC—minimum fungicidal concentration.
