👉 Certainly. Infection, specifically pathogenic infection, occurs when microorganisms such as bacteria, viruses, fungi, or parasites enter and multiply within a host organism, disrupting normal cellular functions and causing disease. This process begins when these pathogens breach the body's defenses, often through breaches in physical barriers like the skin or mucous membranes. Once inside, they can adhere to and invade host cells, exploit cellular machinery for replication, and trigger immune responses that may lead to inflammation and tissue damage. The severity of infection depends on factors such as the type of pathogen, the host's immune status, and the site of entry, potentially resulting in symptoms ranging from mild discomfort to life-threatening conditions. Treatment typically involves antimicrobial therapies to eliminate the pathogens or supportive care to manage symptoms and bolster the body's defenses.
