In Vitro Study of Antibacterial Activity of Mangle negro Extracts Against Selected Pathogens From Enterobacteriaceae and Bacillaceae Families

In this study, the antibacterial activity of Mangle negro extract against selected pathogens from Enterobacteriaceae and Bacillaceae was evaluated.
The antibacterial activity of M. negro ethanolic and aqueous extracts were evaluated, through disk agar diffusion method, extract on medium surface method and microdilution method.
This experimental study after collection and preparation of aqueous and ethanolic extracts of M. negro, their effects against human pathogen microorganism were determined.
The ethanolic and aqueous extracts inhibited the growth of all the organisms tested. The minimum inhibitory concentration (MIC) of the extracts ranged between 4 mg/mL and 64 mg/mL.
The study demonstrated that the ethanolic leaf extract of M. negro hold an excellent potential as an antibacterial agent.
