What is a pathogen?
any disease causing agent
A pathogen is a microorganism, such as a virus, bacterium, fungus, protozoan, or prion, that can cause disease in a host organism. Pathogens are infectious agents that invade and multiply within the cells of a host organism, resulting in damage to tissues and organs, and a disruption of normal body functions. Pathogens can spread from person to person through direct or indirect contact or through vectors such as insects. Understanding the biology and behavior of different pathogens is essential for developing effective treatments and preventive measures.
