Antimicrobials are substances that kill or inhibit the growth of microorganisms, including bacteria, viruses, fungi, and parasites. They are commonly used in medicine to treat infections and can be found in various forms, such as antibiotics, antivirals, antifungals, and antiparasitics. Each type targets specific pathogens, helping to manage diseases effectively. In addition to their medical uses, antimicrobials are also employed in agriculture and food preservation to prevent spoilage and contamination. However, the overuse of antimicrobials has led to the emergence of resistant strains of microorganisms, making it crucial to use these substances responsibly to maintain their effectiveness.
