Abstract

The resurgence of several infections appeared to have been controlled and the increase in bacterial resistance have created the necessity for the development of new antibacterials. In this study the antibacterial efficiency of B. cordifolia leaf extracts were examined using Hexane, Ethyl Acetate, Acetone and Aqueous solution as solvents and tested against pathogens like Vibrio harvayie and Pseudomonas aeroginosa using disc diffusion method. The minimum zone of inhibition was observed in acetone and aqueous solution of B.cordifolia, showing less antimicrobial activity against both experimental strains. The other two extracts, hexane and ethyl acetate showed maximum zone of inhibition against the experimental strains. The antimicrobial activity of B. cordifolia extracts proved that it may be a new and effective herbal medicine to treat the infectious diseases, caused by Pseudomonas aeroginosa and Vibrio harvayie.
