Screening for Antibacterial Activity of Twenty Two Iraqi Wild plants

Abstract

The crude ethanolic extracts of twenty two wild plants growing in the Iraqi south regions was evaluated for antibacterial activities against five bacterial species: Gram positive (Staphylococcus aureus ATCC25923) and Gram negative ( Pseudomonas aeruginosa ATCC27853, Escherichia coli ATCC25922) (Klebsiella pneumonia and Proteus vulgaris) bacteria by agar well diffusion method . The results showed that the Arnebia decumbens exhibit broad spectrum activity against all bacterial species. Of 22 plants tested, 10 showed encouraging antibacterial results against one or more species of bacteria .On the other hand 11 plants species have no activity.
