Glossary Pathogen

microorganism causing disease in its host

A pathogen is a microorganism, such as a virus, bacterium, fungus, or parasite, that can cause disease in its host. These harmful agents invade the body, multiply, and disrupt normal bodily functions, leading to illness. Understanding pathogens is crucial for both preventing and treating infections, as well as for developing vaccines and other medical interventions.
