Abstract

The present study was carried out to evaluate the antimicrobial and antifungal activity of Psidium guajava against three clinically important bacteria and one fungus namely Staphylococcus aureus, E. coli, Bacillus and Candida glaberata, the antimicrobial and antifungal activity of different extracts was done with agar well diffusion assay in plates containing nutrient agar media. The antimicrobial activity of methanolic extracts showed that all the combinations of extracts were effective against the test microorganisms. The patterns of inhibition varied with the different solvent extracts as the tested microorganisms. The methanolic extract of Psidium guajava showed effective antibacterial and antifungal activity.

Keywords: Psidium guajava, Antibacterial and antifungal activity, agar well diffusion assay.
