Antimicrobial Activity of Tagetus Erectus against MDR Pathogens

Elisha Chiragdin | S. N. Singh ^[2] | A. S Moses

Abstract: The antimicrobial activity of Tagetus erectus leaves against pathogenic bacteria was studied. Plant extract was prepared using Methanol and was suspended in DMSO solution. Comparative study of leaf extract was evaluated by Agar well diffusion method against Staphylococcus aureus, Bacillus cereus, Salmonella typhi and Escherichia coli. The study showed maximum Zone of Inhibition (ZOI) against Gram -positive bacteria rather than Gram - negative bacteria which is due to the difference in the cell wall composition of the bacteria. Thus, the Antimicrobial Activity found in the Methanol extract of the leaves showed better inhibitory effect on the Gram - positive bacteria i. e. S. aureus and B. cereus.
