Benzene, petroleum ether, chloroform, methanol and aqueous extracts of five plant species, traditionally used for treatment of ailments of infectious nature were screened for in vitro antibacterial activity against different species of bacteria, Staphylococcus aureus, Streptococcus lactis, Bacillus subtilis, Pseudomonas aeruginosa, Escherichia coli and Salmonella typhi. Antibacterial activity was tested using the disc diffusion method. Most of the activity detected was against Gram positive bacteria.
