Forty eight medicinal plants in Nigeria were screened for their antimicrobial activity. Twenty three (47.91%) of the plants caused over 70% mortality of the test organism which include anopheline and culicine larva. Bacillus spp. andEscherichia coli were shown to be susceptible to the antimicrobial activity of some plants. The antimicrobial activities of plants examined in this study showed that plants are capable of producing toxic materials, which may exert some physiological effect on the target organisms.
