Any disease-producing agent esp. a virus or bacterium or other microorganism.
Disease-causing agent such as virus.
In medicine, any microorganism that causes disease. Most pathogens are parasites, and the diseases they cause are incidental to their search for food or shelter inside the host. Nonparasitic organisms, such as soil bacteria or those living in the human gut and feeding on waste foodstuffs, can also become pathogenic to a person whose immune system or liver is damaged. The larger parasites that can cause disease, such as nematode worms, are not usually described as pathogens. + prikaži više
