Antimicrobials are substances that are used to kill or inhibit the growth of microorganisms such as bacteria, viruses, fungi, and parasites. These substances can be natural or synthetic and are commonly used in healthcare settings to treat infections and prevent the spread of harmful pathogens. Antimicrobials can be administered in various forms, including antibiotics, antiviral drugs, and antifungal medications. Research in this area focuses on developing new antimicrobial agents, improving existing drugs, and understanding mechanisms of action and resistance. This research is critical in the fight against drug-resistant infections and emerging infectious diseases.
