Antibacterial Activity of Aloe Lanata and Aloe Vacillanis Plant Extracts

This study was conducted to evaluate the antibacterial effect of the aqueous and Methanolic extracts of Aloe Lanata and Aloe Vacillanis. Using agar diffusion method, three different concentrations of Aloe extracts were evaluated on Staphylococcus aureus, Escherichia. coli, Pseudomonas aeruginosa, and to compare the effectiveness of extracts with some antibiotics (Ampicillin: Amp, Erythromycin: Erytho, Gentamycin: Genta).The extracts showed that there was a different effect on the bacterial species according to the type and concentration of the plant extract as well as the inhibitory response to the bacterial species. The aqueous and alcoholic extract of A. lanata is more potent than A. vacillanis extract. In comparison to the type of extract, the alcoholic extract of A. lanata was more effective than the aqueous extract, while the aqueous extract of the A. vacillanis showed higher efficacy than the alcoholic extract. Both extracts had the most substantial effect on both E. coli and P. aeroginosa and were less effective on S. aureus. Antibacterial efficacy of studied plant extracts showed better efficacy than the antibiotic (Ampicillin, Erythromycin) on Staphylococcus aureus and E. coli.
