an in vitro evaluation of the antibacterial activity of aloe barbadensis on selected bacterial strains

Introduction: traditional remedies, of which 95% are derived from plants, are used in ethiopia to cure 90% of cattle and over 80% of human patients. traditional medicine continues to be the predominant form of healthcare in underdeveloped nations. aloe barbadensis is used to cure a variety of sick conditions, both infectious and not. the emergence of antimicrobial resistance (amr) in bacteria is a significant risk and issue associated with conventional antibiotic treatment. methods: disc diffusion and minimum inhibitory concentration (mic) experiments against certain zoonotic pathogenic bacteria were used to assess the antibacterial activity of leaf extracts from chosen plants in vitro. the extraction solvents employed in this investigation were ethanol, methanol, and aqueous extraction. results: the ethanol extract from a. barbadensis was 7±0.11mm to 24±0.26 mm. a. barbadensis leaves showed 2±0.11 to 10±0.29 for hot conditions and 3±0.11 lowest to 12±0.26 highest for cold conditions. all examined microorganisms had a significant difference (p<0.05) in ethanol, methanol, and hot and cold aqueous extracts. conclusion: the findings of this study point to the potential use of a. barbadensis extracts as antibacterial agents for developing new pharmaceuticals to control animal pathogenic bacteria responsible for severe sickness.
