Antibacterial refers to substances that kill or inhibit the growth of bacteria. These agents can be found in various forms, including medications, cleaning products, and personal care items. Common antibacterial agents include antibiotics, which are used to treat bacterial infections, and antiseptics, which are applied to the skin to prevent infection. Antibacterial products are widely used in healthcare settings, homes, and food preparation areas to reduce the risk of bacterial contamination. However, the overuse of antibacterial agents can lead to antibiotic resistance, making it harder to treat infections caused by certain bacteria.
