Abstract

Infections caused by multidrug-resistant bacteria are among the most feared diseases in vulnerable individuals and immunocompromised people. In view of the limited number of antibiotics that are truly effective against these bacterial diseases, it is essential to find new drugs that are more active, broad-spectrum, less harmful and costeffective. The antibacterial properties of aqueous and ethanolic extracts 70% of the bark of the Terminalia mantaly trunk were tested on 16 strains, including 14 strains of Pseudomonas aeruginosa Ceftazidimeresistant from sick people and the environment, one strain ATCC 27853 and one strain Ceftazidime-sensitive by solid medium diffusion methods using blotting paper discs and microdilution in liquid medium on microplates, to determine the antibacterial parameters. The results show that the 70% ethanolic extract strongly inhibited all strains compared to reference Ceftazidime and aqueous extract, with minimum inhibitory concentrations ranging from
