In the present study antimicrobial efficiency of Citrullus colocynthis (L.) Schrad was studied on seven bacteria Bacillus subtilis, Escherichia coli, Klebsiella pneumoniae, Proteus vulgaris, Pseudomonas aeruginosa, Salmonella typhi and Staphylococcus aureus. Ethanol, chloroform and petroleum ether extracts were used for antibacterial assay. Growth inhibitions were evaluated by the disc diffusion method. Ethanol extract is more active against Escherichia coli, Proteus vulgaris and Staphylococcus aureus. Pseudomonas aeruginosa and Bacillus subtilis show moderate activity in chloroform extract. Petroleum ether extract is more active against Escherichia coli. All extracts exhibited considerably less activity against Klebsiella pneumoniae and Salmonella typhi.
