Antimicrobial activity is a research area that focuses on the ability of certain substances, such as antibiotics or natural compounds, to inhibit or kill microorganisms such as bacteria, viruses, fungi, and parasites. This research is important for understanding how various compounds can be used to prevent or treat infections and diseases caused by these microorganisms. Researchers in this field often study the mechanisms by which antimicrobial substances work, as well as ways to enhance their effectiveness and combat antimicrobial resistance. Overall, the goal of antimicrobial activity research is to develop new and effective treatments for a wide range of infectious diseases.
