What is a "pathogen"?
A pathogen is a type of microorganism, such as a bacterium, virus, fungus, or parasite, that can cause diseases. These harmful organisms have the ability to invade and multiply within the body, leading to infection and illness. Pathogens can be spread through various ways, including direct contact with infected individuals, contaminated food or water, or insect bites. Understanding and controlling pathogens are critical in preventing the spread of infectious diseases, often through measures such as vaccination and hygiene practices.
Example
The outermost layer of the skin acts as a barrier against pathogens.
Raw meat can taint other foods in the refrigerator with pathogens.
In the human body, immune cells migrate to sites of infection to combat pathogens and promote healing.
During an infection, the number of white corpuscles in the body can increase to fight off pathogens.
In response to an infection, the bone marrow produces more white blood cells to combat the invading pathogens.
