In-Vitro Antibacterial Activity of Leaf and Stem Extract of Passiflora edulis (Passion Fruit) Planted in Federal University of Agriculture Makurdi, Central Nigeria

The organic extracts of Passsiflora edulis were tested for antibacterial activity against clinically important Gram positive and Gram negative bacteria viz Staphylococcus aureus, Bacillus spp, Streptococcus spp, Escherichia coli, Salmonella spp and Shigella spp. The in vitro antibacterial activity was performed by disc diffusion method. The ethyl acetate leaf extract inhibited the growth of S. aureus, Bacillus spp, , Salmonella spp and Shigella spp, excellently. The ethanolic stem extract also showed antibacterial activity against S. aureus, E. coli and Shigella spp while the ethyl acetate leaf extract showed higher spectrum of antibacterial activity as compared to the ethanolic stem extract both at higher concentrations. Passiflora edulis plant could serve as a better source of antibacterial agent.
