Abstract :

To evaluate the antimicrobial activity of solvent extracts from leaf and stem of Tridax procumbens. The Ethyl acetate, Acetone, Hexane and Methanol extracts of Tridax procumbens were evaluated against Grampositive Bacillus cereus (B. cereus), Staphylococcus aureus (S. aureus) and Gram-negative bacteria Escherichia coli (E. coli), Pseudomonas aeruginosa (P. aeruginosa), Klebsiella pneumoniae (K. pneumonia) by using agar well diffusion method. The results revealed that among five pathogenic bacteria. Bacillus subtilis and Staphylococcus aureus belongs Gram-positive bacteria showed higher susceptible for leaf and Stem extracts.
