Antimicrobial Activity of (Cavs.) Pers. Ethanolic and Aqueous Leaf Extract on the Growth and Biofilm Formation of Selected Bacterial Isolates.

Background: (Aunasin) is an endemic Philippine plant of the family Primulaceae, with several studies showing the genus Ardisia as having potential antibacterial, antiangiogenic, cytotoxic, and antipyretic properties.

Objective: This study aims to determine the antibacterial and antibiofilm-forming activity of ethanolic and aqueous extracts on , Methicillin-Sensitive (MSSA), and Methicillin-Resistant (MRSA).

Methods: This is an experimental study testing the activity against bacterial strains of , MSSA, and MRSA using ethanolic and aqueous extracts of leaves.
