 ABSTRACT

Antimicrobial activity of the various species of Ocimum plants like Ocimumbasillicum, Ocimum gratissimum, Ocimum sanctum, Ocimum kilimandscharicum against various pathogens like E.coli, Bacillus subtilis, Streptococcus species, Salmonella typhimurium, Pseudomonas aeruginosa, Staphylococcus aureus, Serratia marcescens, Klebsiella pneumonia were studied with the help of agar well diffusion method.  The antimicrobial activity of the samples with the following solvent extracts Methanol, Ethanol, Chloroform, Acetone, Diethyl ether of  Ocimum gratissimum, Ocimum sanctum purple were measured by using Muller-Hinton agar plates which showed the highest zone of inhibition against Salmonella typhimurium, Pseudomonas aeruginosa and Serratia marcescens. In Ocimum kilimandscharicum,  all the pathogens were resistant against all the extract except for Bacillus subtilis which showed least susceptible to the Methanol extract.

Keywords: Muller-Hinton agar plate, Agar well diffusion method, Zone of inhibition, Pathogens, Medicinal plants.
