Description
The purpose of this study was to investigate the antimicrobial properties of different parts of the aloe plant. Specifically, we examined how aloe gel, latex, and leaves affected the growth of pathogens: Staphylococcus aureus, Klebsiella pneumoniae, Pseudomonas aeruginosa. We analyzed the chemical composition of each aloe component using high performance liquid chromatography. Using a disk diffusion assay, the gel, latex, and rind extracts, along with control and standard solutions were tested for their antibacterial efficacy against three ESKAPE pathogens: S. aureus, K. pneumoniae, and P. aeruginosa. The aloe components showed no inhibition of bacterial growth, while the antibiotics used as positive controls were effective. These findings suggest that further investigation of the aloe components is warranted.
