Abstract

 

The antibacterial activity of different extracts from the leaves of Ocimum gratissimum was tested against Staphylococcus aureus, Escherichia coli, Salmonella typhi and Salmonella typhimurium, pathogenic bacteria that cause diarrhea. These extracts evaluated include cold water extract (CWE), hot water extract (HWE) and steam distillation extract (SDE). Only SDE has inhibitory effects on the selected bacteria and the minimum inhibitory concentration (MIC) ranged from 0.1% for S. aureus to 0.01% for E. coli and S. typhimurium, and 0.001% for S. typhi.

                                                                   

Key words: Antibacterial activity, Ocimum gratissimum, diarrhea.
