Tóm tắt

Vibriosis, caused by Vibrio cholerae and Vibrio alginolyticus, causes mass mortalities and economic losses in aquaculture. With rising antibiotic resistance, sustainable alternatives are needed. This study evaluated garlic essential oil (GEO) for antibacterial activity and stability against these pathogens using agar disk diffusion and broth microdilution assays. GEO showed strong activity, with MICs of 5.6 mg/mL for V. cholerae and 1.4 mg/mL for V. alginolyticus. In agar well diffusion tests (100 mg/mL), GEO produced 42 mm inhibition zones for V. alginolyticus and 3 mm for V. cholerae. However, activity declined after 36 hours due to air exposure and storage, indicating volatility. These results highlight GEO’s potential as an eco-friendly antibiotic alternative, but its instability requires stabilized formulations. Future studies should focus on delivery systems to enhance practical use in vibriosis control and sustainable disease management in aquaculture.
