The mangrove plant of Excoecaria agallocha L. were collected from the Muthupet mangrove forest and used for the extraction of fresh and dried parts of leaves stem and root respectively. These plant materials were used to derive the ethanolic extracts and antibacterial activity of solvent extract were performed by the disc diffusion method, agar well method and minimal inhibitory concentration methods. In the dried plant sample the leaf part of Excoecaria agallocha is having higher inhibitory activity against the pathogenic bacteria compared than the fresh plant extracts of Excoecaria agallocha L.
