The antimicrobial activity of Thespesia populneoides plant extracts was evaluated with important microorganisms belong to plants, humans and aquatic origin. In evaluating antimicrobial activity of T. populneoides hexane, chloroform and methanol crude extracts were used. Agar cup plate method/well diffusion method was used to study the antimicrobial activity of all these crude extracts. Aeromonas hydrophila, Pseudomonas marginales, Penicellium expansum and Ustilago maydis were the most resistant bacteria and fungi. Methanolic crude extracts of T. populneoides showed strong activity against the tested microbial strains. Therefore, this can be selected for further investigation to determine its therapeutic potential. https://www.biotech-asia.org/vol6no1/in-vitro-antimicrobial-properties-of-mangrove-plant-thespesia-populneoides-against-selected-clinical-plant-and-aquatic-pathogens/ Thespesia Populneoides; Plant crude extracts activity; Medicinal plants; Antimicrobial activity
