ABSTRACT
Eucalyptus camaldulensis and Calotropis gigantea are common weed and known for various medicinal properties. The aim of the present study was to screen leaves of Eucalyptus camaldulensis and roots of Calotropis gigantea for the antimicrobial activity against clinical isolates of bacteria. The leaf and root extract were obtained by the organic solvents methanol. The methanolic extract of the E. camaldulensis and C. gigantea was studied for its antagonistic activity against Escherichia coli, Staphylococcus aureus, Proteus vulgaris, Salmonella typhi, Pseudomonas aeruginosa, Bacillus subtilis, Klebsiella pneumonia, Salmonella paratyphi. The results obtained from this study inferred that the leaf extract of Eucalyptus camaldulensis was effectively inhibited the growth of test organism, while Calotropis gigantae did not show the activity which is in combination with E. camaldulensis shows the more activity against all pathogens.
