The Potential of Donkey’s Ear Abalone (Haliotis asinina Linnaeus, 1758) as an Antibacterial Agent and Its Effect on Blood Cholesterol Reduction in Mice (Mus musculus Linnaeus, 1758)

Abstract

Infectious diseases primarily caused by pathogenic bacteria like Staphylococcus aureus and Escherichia coli are commonly treated with antibiotics, which interfere with the growth or kill the bacteria by disrupting metabolism (Mancuso et al., 2021). Incorrect antibiotic use can lead to negative health effects and contribute to multi-drug resistance (Fernández et al., 2016). Marine organisms such as abalones have the potential as an alternative agent of new antibacterial. Abalon extracted with ethyl acetate has been reported to have antimicrobial activity and anthelmintic activity and contains secondary metabolite compounds such as alkaloids, terpenes, and flavonoids (Tortorella et al., 2021).Cholesterol is a vital element necessary for regulating chemical processes in the human body (Luo et al., 2020). However, excessive cholesterol can cause hypercholesterolemia and fat accumulation on the walls of blood vessels, thereby triggering symptoms of atherosclerosis and a decrease in proteins in the body's tissue (Wong et al., 2016). Donkey's ear abalone (Haliotis asinina Linnaeus, 1758) is a natural biota that shows potential in reducing blood cholesterol. Besides being a source of beneficial omega-3 fatty acids, protein, vitamins, and minerals, abalone also possesses bioactive sulfate polysaccharide, peptides, glycoproteins, chitosan, and carotenoids, identified as compounds with antioxidant, anticoagulant, and antimicrobial effects (Zoysa, 2013).
