In this study, the antibacterial activity of crude (aqueous and alcoholic) extracts of the bark and leaf of Croton roxburghii Balak. (Euphorbiaceae) was tested against enteric pathogens causing urinary tract infection (UTI) using the agar cup method, minimum inhibitory concentration (MIC), time kill kinetics and synergy study. The ethanol extract exhibited a significant and broad spectrum of inhibition as compared to the aqueous extract of both the bark and leaf. The highest antibacterial activity was observed against Staphylococcus aureus followed by enteropathogenic and enterotoxigenic Escherichia coli. The diameter of inhibition zones varied from 10 to 18 mm for both aqueous and alcoholic extracts. The MIC value ranged from 356 to 625 μg/ml. This could justify the traditional use of this plant in dysentery and other infections.
