Abstract
Aloe vera L. belonging to family Liliaceae is a very important worldwide
used plant having nutritional as well as medicinal value. It plays an
important role in antimicrobial action. The current study was aimed to
assess of antibacterial activity of ethanolic, methanolic and aqueous
extracts of Aloe vera L. against six bacterial strains (Staphylococcus
aureus; Streptococcus pyogenes; Shigella sonnei; Escherichia coli (1)
(4C11); Escherichia coli (2) (ATCC 13048) and Neisseria gonorrhoeae).
Agar well diffusion method was applied to assess the antibacterial activity
of these extracts. Their antibacterial activities were associated with typical
chemical like gentamicine (antibiotic) as positive control. This study
revealed that S. pyogenes, S. aureus and N. gonorrhoeae had the
maximum inhibition to different extracts of A. vera plant and selected
plant extracts remained less effective against Shigella sonnei, E. coli (1)
and E. coli (2). The data also revealed that methanolic extract showed
relatively more inhibitory effects on bacterial growth as compared to other
solvent extracts
