The research aimedtoevaluate theantibacterial effect of ethanol extract of Acalypha australisagainst eightbacterialstrains (Staphylococcus aureus, Enterococcus faecalis, Escherichia coli, Klebsiella pneumonia, Pseudomonas aeruginosa, Actinomyces, Proteus mirabilis and Streptococcus pneumonia) with concentrations ranged from 3.90 to 2000 µg/ml. The sensitivity of bacterial isolates to various antibiotics was tested by VITIK2 Densi-Check equipment. The xtricate was made by a soaked powder of Acalypha australis with 80%ethanol in the unit of soxhlet extractions and after that was aseptically sifted. The antibacterial effects of theextricate were surveyed utilizing the agar dissemination strategy and the broth microdilution-method, which was utilized to gauge the extract's minimal inhibitory concentration (MIC). Results appearedthat the ethanol-extricate has antibacterial action in a concentration-dependent way, with the normal distance across zone of hindrance watched against bacterial segragates extending from 15±0.5 mm to 25±0.5 mmThe xtract had the greatest effectagainst E. coli, followed by P. aeruginosa, and the least effect against P. mirabilis. The extract's minimal inhibitory concentration varies from one species to another, ranging from 31.25 to 250 µg/ml.
