Abstract
Emergence of antibiotic resistance and toxicity an issue reduce the use of antimicrobial agents and provokes resurgence in research for the development of antimicrobial resistant strains on plants.Azadirachta indica Juss. and Acacia nilotica Linn. are multipurpose medicinal plants with many health benefits. Different parts of these plants show antibacterial effects against a wide variety of human pathogenic bacteria. Hence, the present study was aimed to explore the antibacterial competency of stem bark ofA. indica and A. nilotica extracted with different solvents against human pathogen. The bark extracts (Acetone, Chloroform, Ethanol, Methanol and Water) were tested against randomly selected common pathogens such as Staphylococcus aureus (Gram positive), Klebsiella pnemoniae, Salmonella typhi, E.coli and Proteus spp (Gram negative) using disc diffusion method. The results have shown that the bark extracts possessed antibacterial activities against all the tested bacterial strains except Salmonella typhi. The highest antibacterial activity exhibited by aqueous extracts of A. nilotica against K. pnemoniae followed by A. indica against K. pnemoniae and E. coli. On a comparison between the two bark extracts, A. nilotica shown maximum activity than A. indica.
