ABSTRACT

The antibacterial effect of crude methanol extracts of V. officinalis was examined against six clinical
isolates and standard bacterial strains using agar well diffusion and disc diffusion methods. The leaf
extracts inhibited S. boydii, S. pneumoniae, and S. aureus and the root extract had moderate
inhibition zones against S. boydii and MRSA. Strains like S. boydii, S. pneumoniae and S. aureus
were more sensitive to methanol extracts than E. coli, P. aeruginosa and MRSA. The leaf extract
was found to be more effective to inhibit the organism than the root extract. The MIC value of the
leaf extracts equal to one dilution factor less than MIC value of root extract.
Key words: Antibacterial, Extracts, Inhibition Zone, Human pathogen, V. officinalis
