👉 Infection refers to the process by which pathogens, such as bacteria, viruses, or fungi, invade and multiply within a host's body, leading to disease. When a pathogen enters the body, it can trigger an immune response, but if the infection is severe or the host's defenses are compromised, the pathogen can proliferate unchecked. This often results in symptoms like inflammation, tissue damage, and organ dysfunction. Antimicrobial treatments aim to either eliminate the pathogen or inhibit its growth, thereby preventing or treating the infection. Understanding the mechanisms of infection is crucial for developing effective therapies and preventive measures.
