Anti-microbial refers to substances that kill or inhibit the growth of microorganisms, including bacteria, viruses, fungi, and parasites. These agents can be found in various forms, such as medications, disinfectants, and preservatives. They play a crucial role in preventing infections and maintaining hygiene in healthcare settings, food production, and everyday life. Common examples of anti-microbial agents include antibiotics, which target bacterial infections, and antiseptics, used to clean wounds. The effectiveness of these agents can vary, and the misuse of anti-microbials has led to concerns about antimicrobial resistance, where microorganisms evolve to resist treatment, making infections harder to control.
