Aqueous, Chloroform and methanol extracts of 10 medicinal plants were tested against 10 pathogenic bacteria for their antibacterial activity using disk diffusion method. Methanol extracts of Withania somnifera, Lawsonia inermis, Datura metel, Datura stramonium and Bauhinia racemosa showed significant antibacterial activity against certain bacteria. Methanol extracts of Withania somnifera revealed highest zone of inhibition against Staphylococcus aureus, Proteus vulgaris and Leuconostoc mesenteroides. Among all tested extracts, methanol extract of Lawsnia inermis exhibited antibacterial activity against almost all bacteria except Leuconostoc mesenteroides. Gram-positive bacteria were more susceptible to plant extracts than gram-negative bacteria.
