How does the human body first fight off pathogens?

Once infected cells have sensed an invading pathogen, they secrete molecules called cytokines and chemokines.

Are there any ways to cure diseases caused by pathogens?

However, it is true. For centuries, scientists have figured out ways of using deadly, pathoegenic bacteria, viruses, and protozoa to cure deadly diseases caused by other pathogens. It may seem counterintuitive to cure one illness with another, but it has worked time and time again. And it’s not always that scary.

What are three types of pathogenic microorganisms?

Updated July 03, 2019. Pathogens are microscopic organisms that cause or have the potential to cause disease. Different types of pathogens include bacteria, viruses, protists (amoeba, plasmodium, etc.), fungi, parasitic worms (flatworms and roundworms), and prions.
